Description

Detailed Description of the Invention

[0001]

The present invention relates to an air conditioner,
In particular, it relates to a comfortable air conditioner that provides a comfortable air-conditioned space for users.

[0002]

2. Description of the Related Art A conventional comfortable air conditioner is disclosed in Japanese Patent Laid-Open No. 4-1.
As described in Japanese Patent Publication No. 90050, it is provided with a control device having means for selecting a silent mode and an energy saving mode. This control device sets a relatively low speed, low noise operation mode and a relatively high speed, energy saving mode in the speed control means of the condenser cooling fan, and at the same time, sets the low noise operation mode. It has a switching means for selectively switching to a mode or an energy saving mode. As a result, it is possible to implement the operation that meets the respective requirements.

Further, the air conditioner disclosed in Japanese Patent Laid-Open No. 4-28949 is equipped with means for selecting a capacity mode and a silent mode, so that the user can prioritize the silent mode or the capability mode as needed. Can be selected arbitrarily.

[0004]

However, in the above-mentioned prior art, each of the cooling / warming capacity (air conditioning environment) or noise (noise), and the energy efficiency or noise (noise) which is the ratio of power consumption to the air conditioning environment. Although it has been disclosed that the air conditioner should be operated with priority given to one index, two or more of the three indexes of cooling / warming capacity, quietness (noise) and energy efficiency are simultaneously disclosed. In consideration of the operation of the air conditioner, there is a problem that the user's needs are not dealt with in detail and the user feels dissatisfied.

By the way, for the user, cold / warm ability (amount of hot, just right and cold), power consumption and energy efficiency (amount represented by cold / warm ability / consumed input power)
Noise and noise (noisy, disturbing and comfortable amount) are important evaluation indicators when using an air conditioner. Among them, for example, the evaluation index “cooling / warming ability” has a high priority when the air conditioner is started when the temperature difference between the actual room temperature and the desired temperature is large. Further, in this case, since the operation is performed for a short time, the silent operation is prioritized over the power consumption in the same degree as the air conditioning environment. On the other hand, "power consumption" and "energy efficiency" as evaluation indexes are directly linked to the electricity charges during operation of the air conditioner and are important from the viewpoint of global environment conservation. In addition, the power consumption of the commercial air conditioners for offices and factories is enormous, and for example, in the afternoon in the summer, there is a time zone in which the total power is maximum throughout the year. In this case, in order to meet the demand for a peak cut of electric power, "energy efficiency" as an evaluation index is given the highest priority, and next, the room temperature is kept at the set value rather than the noise (noise), that is, the evaluation index "cold "Warm capacity" is given priority. The evaluation index “quiet” is prioritized in the case of low ambient noise, for example, at night, in the office after leaving work, in a hospital, and during sleep driving. In this case, the cooling / warming capacity / time may be small. In addition, both the amount of human activity and the amount of heat that accompanies it are relatively small, the air conditioning capacity is not required so much, and energy saving is emphasized.

By the way, it is difficult to select these three indexes independently, and there is a trade-off relationship in reality. Therefore, it is impossible to perform control that gives the highest priority to all the indexes. However, as described above, the priority levels of the three indexes required by the user differ depending on the surrounding conditions in which the air conditioner is operated. In general, there is almost no demand for an operation in which all three indexes are given the highest priority at the same time, and it is required to operate the two indexes, which are preferable to the user, at the same time within the operation control range of the air conditioner.

The present invention has been made in order to solve the above-mentioned problems, and its purpose is to make the comfort of the user's sense by using the air-conditioning environment, operating cost and noise as evaluation indexes. It is to provide an air conditioner that can be operated.

The control amount of the air conditioner 7 is calculated based on the information from the air conditioner 6, and the air conditioner 7 is calculated based on the calculation result.
Control. Here, the energy efficiency of the air conditioner is a value obtained by dividing the indoor cooling / warming capacity, that is, the cooling capacity or the heating capacity (kW) by the power consumption (kW), and the indoor temperature time change rate is a unit. It is represented by the rate of increase or decrease in room temperature per hour.

By the way, for the user of the air conditioner,

It is used to control the air conditioner 7.
In addition, since the mainstream of the current air conditioner is a heat pump type, during the cooling operation, the indoor heat exchanger is an evaporator,
The outdoor heat exchanger acts as a condenser. On the other hand, during the heating operation, the indoor and outdoor heat exchangers act as a condenser and an evaporator, respectively, which are opposite to those during the cooling operation. The details of the operation information detecting means 9 of the heat pump type air conditioner are shown in FIG.

The operation information detecting means 9 is a suction temperature detecting means 901 for detecting a suction air temperature 931 at an air outlet provided inside or near the indoor unit body of the air conditioner, and inside the indoor unit body of the air conditioner. Or a blowout temperature detecting means 9 for detecting a blown air temperature 932 at an air outlet provided near the main body.

Among these detecting means, the heat exchangers 23, 2
5, the temperature of the refrigerant in the piping of the decompression mechanism 24 and the compressor 21 is detected by using a thermocouple, a thermistor or the like attached to the surface of the piping. Here, not all the information shown in FIG. 9 is necessarily required to calculate the cooling capacity, the heating capacity, and the power consumption. Some of these sensors may be selectively used in consideration of cost and required accuracy. There are various ammeters as current detecting means, such as an encoder, a pulse tachometer, and a tachometer for detecting the number of revolutions, and a Bourdon tube type pressure gauge, a strain gauge type pressure gauge, etc. for detecting pressure.
It should be noted that these detection values are desired to be signals that can be easily digitized because they are processed by a digital computer.

The three indexes of the cooling / warming capacity, efficiency, and comfort priority of noise input by the user specifically correspond to the following. ◆ The index of cooling / heating capacity corresponds to the cooling capacity and heating capacity of the indoor unit and the rising and falling rates of the indoor air temperature.
Here, the cooling capacity of the indoor unit during the cooling operation and the heating capacity during the heating operation are represented by the following equations.

Q = ρ · V · Δh (1) Q: Cooling capacity or heating capacity ρ: Density of intake air V: Volume flow rate of air flowing through the indoor fan Δh: Indoor intake air and blowout Enthalpy difference from air Also, the cooling capacity during cooling operation is given by the following equation. In general, air is moist air and dehumidifies during cooling operation, so it is necessary to consider the amount of sensible heat and the amount of latent heat of air.

Q = ρ · V · Cp · ΔT + hw · ρ · V · Δx (2) Q: Cooling capacity ρ: Density of intake air V: Volume flow rate of air flowing through the indoor fan Cp: Air Specific heat ΔT: temperature difference between indoor intake air and outlet air hw: enthalpy of water Δx: absolute humidity difference between indoor intake air and outlet air Since the heating capacity during heating operation only needs to consider the amount of sensible heat, Only the first term of equation (2) becomes.

Q = ρVCpΔT (3) Q: Heating capacity ρ: Density of sucked air V: Volumetric flow rate of air flowing through the indoor fan Cp: Specific heat of air ΔT: Room suction Temperature difference between air and blown air Here, the specific heat of air, the density of air, the enthalpy of water, and the moist air diagram are stored in advance in the storage device 17.
The temperatures of indoor and outdoor air (eg, dry-bulb temperature and wet-bulb temperature) are detected by an indoor-intake-air temperature detection sensor 901 and an indoor-outlet air temperature detection sensor 902, respectively. In addition, the humidity (for example, relative humidity) of the indoor intake air and the exhaust air is respectively the indoor intake air humidity sensor 32,
The indoor blown air humidity sensor 109 detects it. The density of the air and the absolute humidity of the air are one of the dry bulb temperature and the wet bulb temperature, the dry bulb temperature and the relative humidity, the wet bulb temperature and the relative humidity on the wet air diagram stored in the storage device 17. Determined from the combination. Further, the volume flow rate of the air flowing through the indoor fan is determined by the indoor fan rotation number detection sensor 913 based on the relationship between the fan rotation number and the fan air volume (volume flow rate) stored in advance in the storage device 17. Calculated from information. Also, the radiometer 1 installed in the room
Information from 11 may be considered. Note that the cooling rate, the heating ability, and the rate of increase or decrease of the room temperature are calculated by the control amount calculation means 8, and the information is stored in the storage device 17.

The index of efficiency corresponds to the amount of power consumption and the coefficient of performance. In the present embodiment, the amount of power consumption is detected by the environmental information detecting means 14 (3) from the ammeter 915 provided between the power supply 28 and the air conditioner operation control device 16, and the information is stored in the storage device 17 ( Store in 4). Here, the coefficient of performance is the ratio between the cooling capacity and the input and the heating capacity and the input during the cooling operation and the heating operation, respectively. The input is the above-mentioned power consumption, and the cooling capacity and the heating capacity are the quantities expressed by the above equations (1) to (3).

[0039] Incidentally, when the proportion in the power consumption of the control unit of the air conditioner is relatively small, the power consumption W _t of the air conditioner, the compressor power consumption W _c and the indoor cooling fan It is represented by the sum of the power consumption W _i and the power consumption W _o of the outdoor cooling fan. The power consumption (W _c ) 945 of the compressor is
Since the power characteristic of the compressor including the compressor is known, it can be calculated from the input current value detected by the input current detecting means 915 of the compressor motor. Power consumption of indoor cooling fan (W _i ) 94
6 and outdoor cooling fan power consumption (W _o ) 947,
It is calculated from the input current value detected by the current detection means 916 provided in the indoor cooling fan and the current detection means 917 provided in the outdoor cooling fan. Of course, when the manufacturing cost can be tolerated, the power consumption of each motor may be directly measured by a power meter or the current consumption may be indirectly detected by using an ammeter. The energy efficiency, which is a measure of energy saving, is a value obtained by dividing the cooling or heating capacity q of the air conditioner by the power consumption W _t , and thus can be obtained by calculating the cooling / heating capacity using the above equation. . The power consumption amount and the coefficient of performance are calculated by the control amount calculation means 8, and the information is stored in the storage device 17 (4).

The noise index corresponds to the operating sound of the indoor unit. In this embodiment, the noise of the indoor unit is dominated by the blowing noise of the indoor fan, and since the blowing noise of the fan is proportional to the sixth power of the fan rotation speed, it is stored in the storage device 17 (4) in advance. The operation noise is calculated from the relationship between the fan rotation speed and the blowing noise. Further, a sound level meter or a noise detection microphone may be installed in the indoor unit.

The noise index corresponds to two types of noise, indoor and outdoor. The indoor noise is composed of the noise of the cooling fan provided in the indoor heat exchanger, the electromagnetic noise of the motor driving the fan, and the flowing noise of the refrigerant flowing in the pipe. On the other hand, the outdoor noise is further composed of compressor noise. Among them, the motor electromagnetic noise, the refrigerant flow noise flowing in the pipe, and the compressor noise are radiated through the walls substantially sealed by the motor or the refrigerant pipe or the pressure vessel, respectively, and the surfaces of those walls are radiated. Since it is almost proportional to the magnitude of vibration, there are many cases in which the problem can be solved by attaching a damping material capable of eliminating energy to the surface.

On the other hand, the cause of the noise generated in the indoor and outdoor fans, which is the main noise source of the air conditioner, is vortices on the surface of the fan and in the vicinity of the periphery. However, in order to prevent the generation of this vortex, it is impossible for the air conditioner to adopt a closed or semi-closed structure that hinders the flow of cooling air.
Therefore, an effective measure for reducing noise is to increase the size of the fan, but this method cannot be adopted for an air conditioner that requires compactness. Since the fan noise is proportional to the sixth power of the rotation speed of the fan, the operation sound is calculated from the relationship between the fan rotation speed and the blowing sound that is stored in the storage device 17 (4) in advance. Further, a noise meter or a microphone 112 for detecting noise may be installed in the indoor unit to detect noise. The driving sound of the indoor unit is calculated by the driving information calculation control device 14, and the result is stored in the storage device 17.

FIG. 5 shows the details of the environmental information detecting means 3. The environmental information detection unit 3 includes an indoor temperature detection unit 301 that detects an indoor temperature, an indoor temperature detection unit 302 that detects an indoor humidity, and an outdoor temperature detection unit 30 that detects an outdoor temperature.
3, an outdoor temperature detecting means 304 for detecting the outdoor humidity, and a solar radiation amount detecting means 305 for detecting the solar radiation amount. Among these pieces of information, the indoor temperature changes due to heat absorption or exhaust heat due to the operation of the air conditioner, and the indoor humidity changes due to humidification or dehumidification. It should be noted that not all of this information is necessarily required, and it is sufficient to use it as needed.

FIG. 6 shows details of the control amount calculation means 8.
The control amount calculation means 8 is a control target determination means 81 for determining a control target from three types of information, that is, environmental information such as indoor temperature, user environment setting information such as target indoor temperature, and comfort priority information. The control amount determining unit 82 determines the control amount of the air conditioner 7 based on the control target determined by the control target determining unit 81. By the way, the control amount computing means 8 may use the operation information shown in FIG. 3 in addition to the above three types of information (see FIG. 7). In this case, a more comfortable operation of the air conditioner becomes possible.

FIG. 8 shows details of the control target determining means 81 shown in FIG. The deviation calculation means 811 calculates the temperature difference between the target room temperature, which is one of the user-set environment information, and the room temperature as the environment information. Then, the relationship between the temperature difference and the rotation speed of the compressor or the cooling fan, which is the cycle control amount, in the reference state, and the like are stored in the cycle control estimated amount storage unit 812. The standard cycle control amount calculation unit 813 calculates the reference cycle control amount based on the output information from the deviation calculation unit 811 and the cycle control estimated amount storage unit 812.

The cooling / warming capacity factor estimated amount storage means 814 stores the reference efficiency, the air conditioning capacity or the cooling / heating capacity of the standard room temperature time change rate, the noise index, or the correlation with the three indexes. A high quantity, that is, the relationship between the performance factor and the cycle control quantity is stored. The standard cooling / heating capacity factor calculating means 815 is the standard cycle control amount calculating means 813.
Cooling / warming capacity factor estimation amount storage means 8 based on the output information of
14, the reference performance factor is calculated.

The target performance factor increase / decrease rate of three indexes of cooling / heating capacity and noise is calculated.

In the embodiment shown in FIG. 8, the database
Although the information stored in the form of a table is used, the evaluation that the temperature is high / low and the sound is high / low is determined by the user's feeling, and the ambiguity remains. Therefore, if a fuzzy operation is used using a certain predetermined control rule, the increase / decrease rate of the target performance factors of the three indices of efficiency, cooling / warming capacity, and noise can be calculated when calculating the cycle control estimation amount. Is effective when doing.

Next, FIG. 9 shows a modification of FIG. 8 in which the increase / decrease rate of the target capacity factor is calculated by using the driving information as well. in this case,
The control amount determining means 82 has a physical property value storage means 818 instead of the cooling / warming capacity factor estimated amount storage means 814 shown in FIG.
And an air conditioner specification storage means 819. The physical property value storage unit 818 stores the physical property values of the refrigerant and the air, and the air conditioner specification storage unit 819 stores the relationship between the compressor discharge amount and the fan discharge air amount and the rotation speed. There is. The standard capacity factor calculating means 815 calculates a standard capacity factor using the output information of the standard cycle control amount calculating means 813 and the deviation calculating means 8101 and the operation information of the air conditioner. In the embodiment shown in FIG. 8, when calculating the standard capacity factor, the relationship between the temperature difference and the rotation speed of the compressor or the cooling fan, which is the cycle control amount, is used. The standard capacity factor can be obtained by using the physical property values and the specifications of the air conditioner, which simplifies the control system.

FIG. 10 shows a detailed structure of the control amount determining means 82. The relationship between the cooling / warming capacity factor increase / decrease rate and the cycle control amount is stored in the cycle device control estimated amount storage unit 821 included in the control target determining unit 81. The control amount calculation means 822 uses the output of the target capacity factor increase / decrease rate calculation means 817 to obtain the control amount of the cycle equipment by referring to the cycle equipment control estimated amount storage means 821 to cool the compressor and the indoor heat exchanger. It controls a cycle device of the air conditioner 7, such as a fan or an outdoor heat exchanger cooling fan.

Next, the operation of the control device of the air conditioner after the comfort priority is input will be described. ◆ When the user inputs a priority level for each index of the comfort priority level from the comfort priority level input means 5 in a five-level evaluation, the information is set in the comfort priority level setting device 29 and recorded in the storage device 17. It
The air conditioner operation control device 16 takes out the environmental condition input by the user from the storage device 17, and selects the standard operating condition as a reference corresponding to the information from the operating condition information stored in advance in the storage device 17. . The information on the operating conditions includes, for example, the rotation speed of the compressor and the rotation speeds of the indoor and outdoor fans. At this time, the air conditioner operation control device 1
In 6, the indexes such as the cooling / warming capacity, the efficiency and the driving noise during the standard operation are calculated. Next, the comfort priority setting device 29 converts the value input by the user from the comfort priority input means 5 into a weighting coefficient for each item and stores it in the storage device 17. Air conditioner operation control device 16
Retrieves this information from the storage device 17, weights each of the previously calculated indices of cooling / warming capacity, efficiency, and operating sound during standard operation, and stores the operating conditions corresponding to that information in the storage device 17 in advance. The selected operating condition information is used as the actual operating condition information. The information on the actual operating conditions includes, for example, the rotation speed of the compressor and the rotation speeds of the indoor and outdoor fans, as described above. The air conditioner operation control device 16 determines the compressor 21 and the outdoor fan 26 based on the set values of the rotational speed of the compressor and the rotational speeds of the indoor and outdoor fans.
Also, the indoor fan 27 is controlled.

During operation of the air conditioner, the operation information calculation control device 14 and the environment information calculation control device 15 operate to sequentially sense and calculate various information, and store new information in the storage device 17. . The air conditioner operation control device 16 also retrieves new information from the sequential storage device 17 and constantly compares the actual operation condition information obtained by recalculation with the standard operation information so as to comply with the settings input by the user. Perform feedback control.

11 to 14 show details of the comfort priority input means 5 used for the above-mentioned control. The comfort priority input means 5 uses three indicators, namely, the cooling / warming capacity or the cooling rate of the air conditioner represented by the time rate of change of the indoor temperature.
The heating capacity 501, the efficiency 502 represented by the power consumption or energy efficiency of the air conditioner, and at least two of the three indexes of the noise 503 can be arbitrarily set by the user. The comfort priority input means 5 is
The cooling / warming capacity selection range display unit 511 and the power consumption selection range display unit 52 are associated with the three indexes of the heating capacity, efficiency, and noise.
1. A noise selection range display section 531 is provided. A plurality of selection range buttons, six in the case of FIG. 11, are installed on each display unit. Each selection range button 51
Priorities among these three indices are assigned in the order in which 2, 522 and 532 are pressed, and a signal according to the priority of each selected range is output from the comfort priority input means 5.

In this embodiment, when one button in the range selection button group is pressed for a certain index at the beginning, the selectable range of the other selected index is clearly indicated to the user by lighting or blinking the button, and the selected index is used. The person will select from the range that is lit or blinking. Figure 1 shows this situation.
It is shown in FIG. Each selection index has a selection range of 6 levels. As the highest priority, the button 515 in the selection range button group 514 of the cooling / warming capacity selection index display portion 513 is pressed. Then, the button 525 in the selection button group 524 of the power consumption index display unit 523, which indicates the range of the third to fifth stages, lights up (filled display). Similarly, the button 535 in the selection button group 534 of the noise index display portion 533, which indicates the range of the first to third stages, lights up. Therefore, as the next priority, for example, if the fourth stage button in the power consumption selection range button group is pressed, only the first stage button in the noise selection range button group is lit. As a result, a signal according to the priority of each selection range is output from the comfort priority input means 5.

By the way, in the case of steady operation, the cooling / warming ability is determined based on the set temperature and does not need to be selected. Therefore, the selectable range of power consumption and noise is utilized by lighting or blinking the button. Clearly indicate to the person who can make a choice within that range. In this case, whichever of the power consumption and the noise selection button is pressed first has priority.

FIG. 13 shows another embodiment of the comfort priority input means 5. The display portion of the comfort priority input means 5 has priority ratios of 518, 528, 538 for the selection indexes of the cooling / heating capacity 516, the power consumption 526, and the noise 536.
Is shown on the pie chart as The selection rate for each index is a value between 0 and 100%, and the total of all selection rates is 100%. Each selection button 51
Depending on the time or number of pressing 7, 527, 537, the priority ratio of each index is displayed in a pie chart, the priority is set in descending order of priority ratio of the selection range, and the signal corresponding to the ratio of the priority order is the comfort priority. It is output from the input means 5.

FIG. 14 shows another modification of the comfort priority input means 5. The comfort priority input means 5 has a cooling / warming capacity index display unit 543, a power consumption index 553, and a noise selection index display unit 563, and each display unit has:
Selection range button groups 545, 555, 565 are provided. In the case of steady operation, the operating range of cooling / warming capacity, power consumption, and noise is indicated to the user by lighting the button, and from this display, if the user seems to use a lot of electricity, Using the power consumption selection range button, the air conditioner is instructed to reduce the power consumption. Also,
If the noise is annoying, the air conditioner is instructed to reduce the noise by using the noise selection range button.
Further, when it is too hot or too cold, the cooling / warming capacity selection button is used to change the cooling / heating capacity and give a command. In addition, lock buttons 544 and 55 are provided for each index.
4, 564 are provided, and the selected value of the selected index can be held by pressing this lock button.

In this embodiment, the comfort priority input means 5 and the user environment setting means 1 are separated, but they may be integrated. Further, the comfort priority setting device 29, the driving information calculation control device 14, the environmental condition setting device 13, the environmental information calculation control device 15, the air conditioner driving control device 16 and the storage device 17 are separate but integrated. May be.

Further, there may be provided a display means for displaying the control results for at least two indexes (two quantities) among the indexes of the cooling / heating capacity and efficiency, the noise, or the quantities highly correlated with these indexes. Good. The display location is not limited, and if the control result is displayed in a member in which the comfort priority input means 5 and the user environment setting means 3 are integrated, cost reduction and space efficiency can be improved. A factory becomes possible.

FIG. 15 shows another embodiment of the present invention for controlling the air conditioner using the intelligent control amount calculation means 11. The intelligent control amount calculation means 11 is known using a neural network having a fuzzy calculation or learning function based on environment information, user environment setting information, comfort priority information, and driving information. Calculate the controlled variable. An example of the calculation of the intelligent control amount will be shown below with reference to FIGS.

FIG. 16 shows an example of an inference rule for estimating the rotation speed of the cooling fan attached to the indoor unit heat exchanger. In this example, the power consumption as an efficiency index and the cold / warm capacity as a cold / warm capacity index are taken out of the three indexes. With respect to these two indexes, the rotation speed of the cooling fan attached to the heat exchanger of the indoor unit is estimated as an example of the cycle control amount. Specifically, when it is desired to reduce the power consumption and increase the cooling / warming capacity, the rotation speed of the compressor is reduced and the rotation speed of the cooling fan is increased. If you want to maintain cooling / warming capacity and reduce power consumption, increase the cooling fan rotation speed to increase cooling / warming capacity and lower the compressor rotation speed to reduce the electrical input to the compressor. Let At this time, noise is not controlled.

FIG. 17 shows an example of an inference rule for estimating the rotation speed of the compressor. In this case, the rotation speed of the compressor, which is one of the cycle control amounts, is estimated by using the cooling / heating capacity and the noise among the three indexes. Then, when it is desired to increase the cooling / warming ability and reduce the noise, the rotation speed of the cooling fan is decreased and the rotation speed of the compressor is increased. Further, since noise may be loud, it is necessary to increase both the rotation speed of the cooling fan and the rotation speed of the compressor when it is desired to cool the room rapidly. At this time,
Power consumption is not controlled. In this way, it is possible to create a rule in which at least two indexes or two control quantities are combined from the control quantity of each cycle and three indexes or three control quantities having high correlation with these three indexes.

18 to 20 show an example of the membership function when the fuzzy control is used. In this,
18 shows the amount of change in efficiency, FIG. 19 shows the amount of change in noise, and FIG.
Shows the membership functions of the amount of change in cooling / heating capacity, respectively. The grade representing the degree of conformity to the membership function is obtained, and the rotation speeds of the cooling fan and the compressor are controlled by using the control rules shown in FIGS.

In the above embodiment, the indoor noise radiated from the air conditioner into the room as noise was mainly described, but when it is necessary to maintain the outdoor environment, the same reasoning is applied to the outdoor noise. You can build a rule and deal with it. Further, in the above embodiment, the separate type air conditioner in which the indoor unit and the outdoor unit are separated has been described, but for example, the window type air conditioner, the refrigerator, the showcase.
Even if all the refrigeration cycles are in the same space, such as a cooling system, the same method as described above can be used.

As described above, according to the present embodiment, in the air conditioner, the cooling / warming capacity, power consumption and energy efficiency (= cooling / warming capacity / consumed input power), and noise are compared with three indexes. Since the user can select a plurality of priorities, the user can obtain a comfortable air-conditioned space.
