Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention enables an air conditioner and an air blower such as a fan provided separately from the air conditioner to operate in parallel in the same room. The present invention relates to an air conditioner, a blower, and an operation control device for these.

2. Description of the Related Art Generally, a system is widely known in which an air conditioner is installed in a room and the room is cooled or heated to obtain an air conditioning effect.

Further, as disclosed in JP-A-61-52530 and JP-A-61-52531, during air conditioning, conditions such as humidity or dirt of the air are detected, and a humidifier or a ventilation fan is driven,
It is also known to control for further improvement of comfort.

However, in the former general air conditioning system, the temperature of the entire room is controlled, so that the load on the air conditioner is large and the power consumption is large. This power consumption is large as the set temperature in the room has a large difference from the current temperature.

In addition, the latter control can improve comfort of air conditioning, but cannot reduce power consumption.

In view of the above conventional problems, the present invention is to provide an operation control device that can achieve the following objects.

An object of the present invention is to obtain a cooling effect by an air flow in addition to an air conditioning (particularly lowering of room temperature) action by an air conditioner.

Another object of the present invention is to simplify the operation operation of the air conditioning effect and the cooling effect by the air flow.

Still another object of the present invention is to reduce power consumption by adding a cooling action by an air flow.

That is, a compressor and a heat exchanger. An air conditioner including a blower, a blower unit installed indoors and operated independently of the blower of the air conditioner, a first signal receiving unit provided in the air conditioner, and the blower And a remote control device for outputting an operation control signal such as an infrared ray to each of the first and second signal receiving parts, the remote control device comprising: First operation mode storage means for operating only the air conditioner, second operation mode storage means for parallel operation of the air conditioner and blower means, and either one of the first and second operations The selecting means for selecting a mode signal and the first or second operation mode signal selected by the selecting means are set to the first,
A second output means for outputting to each signal receiving section,
Further, the first signal receiving portion is provided with a first operating means for controlling the operation of the air conditioner in response to a signal from the remote control device, and the second signal receiving portion is provided with the remote control device. Second operation means for controlling the operation of the blower means by the second operation mode signal of the above, and further, any one of the first operation means, the remote control device, or the blower means has a load such as an indoor temperature. Indoor load detecting means for detecting the indoor load, indoor load setting means for setting a target value of the indoor load, set load storing means for storing the target value set by the indoor load setting means, and detection by the indoor load detecting means.

Control means for controlling the operation of a load such as a blower;
The setting load correction means for increasing the target value stored in the setting load storage means is provided at the time of the operation mode signal.

By such means, the operation control device can optionally add the feeling of cool air due to the air flow to the air conditioning operation by the air conditioner, which makes it possible to reduce the power consumption and make the ambient temperature of the human body uniform. It is possible to prevent the insensation phenomenon of the cooling feeling, that is, the swelling phenomenon.

Further, by correcting the set value of the room temperature or the like with the operation of the blower, it is possible to further reduce the power consumption and prevent discomfort due to excessive cooling.

Next, an example of a specific configuration of the circuit shown in FIG. 2 will be described with reference to FIG.

Here, the air conditioner is mainly one in which each device is controlled by a microcomputer, and the load in the room is temperature. Further, the circuit configurations of the remote control device 3 and the fan 2 may be well-known configurations.
The description is omitted. The same parts as those in FIGS. 1 and 2 are designated by the same reference numerals and the description thereof will be omitted.

In the figure, reference numeral 10 is a microcomputer, which is provided with the operation signal judging means 1e and the control means 1j shown in FIG. Reference numeral 11 denotes a thermistor for detecting room temperature, which corresponds to the indoor load detecting means 1f in FIG. Reference numeral 12 denotes a room temperature setting resistor for setting the room temperature, which corresponds to the set load storage means 1g in FIG. Reference numeral 13 is a comparator, which corresponds to the comparing means 1h in FIG. Reference numerals 14a and 14b are correction resistors and relays for correcting the inversion reference value of the comparator 13, and correspond to the set load correction means 1k in FIG. Reference numerals 15/16 and 17 denote a compressor, an outdoor fan motor, and an indoor fan motor, respectively. The indoor fan motor 17 is a high-speed (H) / medium-speed (M) / low-speed (L) shift tap. And has switching operation by relays 18, 19, 20. The operation of the compressor 15 is controlled by the relay 21. Each of the relays 14b, 18, 19, 20, 2
Energization of 1 is controlled by transistors 22, 23, 24, 25, and 26 connected to the respective ports of the microcomputer 10. 27 is a power source and 28 is a power switch.

Needless to say, the room temperature setting and determination function or the set load correction function is not limited to the configuration of FIG. 3 and can be realized by the program processing of the microcomputer.

Next, the operation of the above system configuration including FIG. 4 will be described. Here, for convenience of description, a description will be given of the first operation mode and the case where the first operation mode is changed to the second operation mode.

First, the first operation mode will be described.

The operation switch is turned on and the air conditioner (indoor unit)
When 1 is operated, the thermistor 11 detects the room temperature t, and the comparator 13 operates as shown in step 1 of FIG.
The indoor temperature t and the temperature t ₁ set by the room temperature setting resistor 12 are taken in, and the comparison is continued. This operation corresponds to step 2 and step 4 in FIG. Simultaneously with this operation, the microcomputer 10 (operation signal determination means 1e) causes the electric fan 2 to operate in parallel in step 3 of FIG.
However, since it is the first operation mode, the temperature in the room is maintained at the set value t ₁ by the operations shown in steps 4 to 6.

The above operation is the basic control content of a normal air conditioner alone, but various functional operations may be added during steps 1 to 6 as necessary.

Next, in the above operation, the remote control device 3
When the signal of the operation mode is output, the microcomputer 10 outputs to the first signal receiving section 1c of the air conditioner 1 that the fan 2 can be operated by the output means 2f in step 3 of FIG. 4 (step 7). Then, as shown in step 8 of FIG. 4, when the operation signal judging means 1e of the microcomputer 10 confirms the output, the microcomputer 10 operates the transistor 22 to set the temperature.
The t ₁ is changed to the set value t ₂ to which the correction value α is added (step 9).

Then, the process proceeds to step 10, the fan 2 is operated, and the cooling operation is controlled until the condition of step 11 is satisfied.

The control of the cooling operation is performed by operating the relay 21 by the operation of the transistor 26 by the microcomputer 10 and continuously operating the compressor 15.

By the above operation, the cooling effect by the air flow is added to the human body, the cold air effect can be obtained, and the room temperature is the set value t ₂
Maintained at.

Here, when the power of the fan 2 is not turned on in the second operation mode, or when the power of the fan 2 is turned off during the second operation mode, the fan 2 is turned off.
If is stopped, the above-mentioned step 7 is not executed, so the set temperature t ₁ is not changed. As a result, it is possible to prevent the first operation mode in the room from continuing and to prevent room temperature from rising and causing discomfort.

Next, another embodiment of the present invention will be described with reference to FIG.

The embodiment shown in FIG. 5 relates to the fan 2.
Further effects can be expected when used for the control of the above embodiment.

That is, the fan 2 of this embodiment is the fan 2 of FIG.
In addition to the above configuration, an indoor temperature detecting means 2g for detecting the indoor temperature at the beginning of operation and a target value obtained by subtracting a correction value of a predetermined value (for example, 2 ° C.) from the detected value of the indoor temperature detecting means 2g are set. When the values detected by the temperature setting means 2h and the room temperature detecting means 2g reach the target value of the temperature setting means 2h, the output means 2j for outputting a deceleration signal to the speed changing means 2i for decelerating the rotation speed of the fan 2. Is provided.

In FIG. 5, the driving means 2k is the motor unit 2b of FIG.
And the blowing means 2l corresponds to the fan unit 2c in FIG.

The control of the fan 2 having such a configuration is applied when the room is cooled to some extent by the air conditioner.

Therefore, this fan 2 is preferably used when the cooling is suddenly started from the second operation mode.

Incidentally, in the above-mentioned embodiment, although the case of using a fan as the air blower or the air blower is described, the air blower, the air blower, for example, a circulator or a recently developed local air conditioner, is not limited to these. A ventilation means that brings a cool air effect to the human body by the air flow,
Any blower may be used.

In addition, the detection of the indoor load of the air conditioner is not limited to room temperature, but it may be converted into room temperature by detecting the refrigerant pressure, temperature, etc. during the refrigeration cycle and taking into consideration the operating time and the like.

Further, the air conditioner is not limited to the separate type, but may be an integrated air conditioner whose capacity is relatively difficult to increase.

Further, if necessary, the air blowing means and the air blowing device may be provided with air blowing direction changing means, continuous air blowing means, or the like to further prevent the air-conditioning feeling from being evenly distributed.

EFFECTS OF THE INVENTION As is apparent from the above-mentioned embodiments, the present invention has the cooling effect not only in temperature but also in air flow, so compared to the air conditioning effect obtained by simply lowering the temperature by the air conditioner, The feeling is not uneven and the comfort is improved, and the airflow produces a cool air effect, so the room temperature setting temperature of the air conditioner can be set higher, and power consumption can be reduced accordingly. . In addition, the cool air effect of this air flow is small in heat shock when it leaves the room in which the air conditioning is being performed, and a sensationally excellent air conditioning effect is obtained.

In addition, with the operation control device, operation of only the air conditioner,
Since the air conditioner and the air blower (air blower) can be selectively operated in parallel, control with excellent operability can be obtained.

Furthermore, when the air conditioner and the air blower (air blower) are operating in parallel, the room temperature set value of the air conditioner automatically slides, so that discomfort due to excessive cooling and unnecessary power consumption can be prevented.
