JPH03260537A - Optimum start control advancing time deciding system for air conditioner - Google Patents

Abstract

PURPOSE:To decide optimum start control time by considering the end of a holiday in which an air conditioner is not used by referring to an advancing pattern at the end of the holiday different from a weekday advancing pattern to calculate advancing time in the case of a service. CONSTITUTION:When an operator sets an indoor target temperature, a room using time, etc., on a setting board 4, a CPU 1 compares a calendar 1-3 with holiday end data written from a disk 2 in a memory 3 by a comparator 1-1, and judges whether it is the end of the holiday or not. In the case of the end of the holiday, the CPU 1 extracts an advancing pattern for the end of the holiday held in the disk 2, and decides the starting time of an air conditioner 5A by referring to a temperature difference between an indoor temperature measured by a sensor 6A and the indoor target temperature and the advancing pattern for the end of the holiday. The conditioner 5A is started according to the decision to obtain an optimum environment at room use starting time.

[Industrial application field]

The present invention relates to air conditioner control for building equipment, etc., and relates to a method for determining the advance time of an air conditioner in order to optimize the indoor temperature at the time of starting use of the room.

[Conventional technology]

BACKGROUND ART Air conditioners, which are a type of building equipment, need to have an optimal indoor temperature for each room or floor in a building at the time they start being used.

For this reason, conventionally, the start time and stop time of the air conditioner were set in advance according to the time of use of the room or floor, and automatic operation was performed using a computer. When setting this startup time, we set the startup time so that the room temperature is optimal when the room starts to be used.
Start up the air conditioner before the room starts to be used (startup)
It is necessary to

The operating time from the start time of the air conditioner until it reaches the target temperature is called the advance time of the air conditioner.

To determine the advance time for this air conditioner, each air conditioner has a different capacity and also varies depending on the area of the room covered by each air conditioner, so refer to the advance schedule described below for each air conditioner and use the Indoor target temperature (for example, 23℃ in summer,
In winter, the time required to bring the time forward was calculated once a day based on the temperature difference between the temperature in the room before the air conditioner was activated (for example, 26 degrees Celsius in winter) and the advance schedule.

The advance pattern is a graph showing the relationship between the temperature difference between the indoor temperature before the air conditioner operates and the indoor target temperature, and the advance time, as shown in pattern M2 in FIG. It is expressed as The operator determines the advance time Y1 corresponding to the temperature difference X1 between the indoor temperature and the indoor target temperature from the advance advance pattern as shown in FIG. 6, and starts the operation of the air conditioner by the time Y1 earlier than the room use start time.

The operator also monitors the indoor temperature and the time it takes to reach the indoor target temperature after starting the air conditioner, and reflects this in the advance schedule.

For example, in FIG. 6, if the temperature difference becomes X2 when the air conditioner is operated for a time of Y2, the advance time pattern M2 is corrected to a pattern MY', and the advance time for the next day is calculated according to this.

In this way, the graph of the advance pattern is rewritten based on the daily measurement results, and is reflected in the next day's advance pattern. In FIG. 6, point Mo represents the maximum temperature difference Xo and advance time Yo determined from the operator's experience.

There are usually about 15 such advance patterns for cooling and heating, and the operator determines the advance time using an appropriate pattern depending on the situation.

[Problem to be solved by the invention]

However, for example, in actual office building equipment, Saturdays, Sundays, holidays, etc. are holidays, and as a general rule, air conditioners are not used on holidays. Therefore, since there is no influence from the previous day's air conditioning, even if the rising temperature difference on the day after a holiday such as Monday is the same as the temperature difference on weekdays, it will take more time to reach the target temperature than on weekdays. .

In this way, after a holiday, the temperature rises slowly, so if you use the conventional advance pattern based on measurement results, it will take more than the expected advance time to reach the indoor target temperature, and even when the room starts to be used, the temperature will not be optimal. The problem is that the environment is not available.

Accordingly, an object of the present invention is to provide an optimal startup control time determination method that takes into account the end of holidays when the air conditioner is not used when determining the advance time of the air conditioner.

[Means for Solving the Problems] In order to achieve the above object, the present invention uses a system that refers to the advance schedule for holidays and dawn, which is different from the advance schedule for weekdays, when calculating the advance time when operating the air conditioner. This is what I did.

FIG. 1 is a diagram showing the inventive principle of the present invention, FIG. 1(a) is a block diagram of a control circuit for calculating advance time of the present invention, and FIG. show.

In Figure 1(a), 1 is a CPU, 2 is a disk, 3
4 is a memory, 4 is a setting panel, 5A is an air conditioner, and 6A is a sensor. The CPU has at least comparator 1-1 and timer 1.
-2, calendars 1-3 are built in, and disk 2 holds data for holidays and evenings, advance patterns for holidays and evenings, advance patterns for weekdays, air conditioner number, indoor target temperature, etc., and these are stored from CPU 1. The information is stored in the memory 3 in response to a request from the user.

[Effect]

When the operator sets the indoor target temperature, room usage time, etc. on the setting panel 4, the CPU compares the calendar 13 with the holiday and daytime data entered in the memory 3 from the disk 2 using the comparator 1-.
1 to determine whether it is the end of a holiday. If it is the end of a holiday, the CPUI will display the data in Figure 1 (b
) is extracted, and the air conditioner is adjusted to 1!5A by referring to the temperature difference between the indoor temperature measured by the sensor 6A and the indoor target temperature and the pattern that the holiday is brought forward.
Determine the startup time. According to this decision, air conditioning 115A
By activating the system, an optimal environment can be obtained at the time the room starts to be used.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 2 to 5.

FIG. 2 is a configuration block diagram showing one embodiment of the present invention;
This figure is an explanatory diagram of the operation of FIG. 2, FIG. 4 shows an example of data for the day after a holiday, and FIG. 5 shows an example of a front-loaded button for the day after a holiday.

In FIG. 2, the same symbols as in FIG. 1 indicate the same parts,
1 is a CPU, which has at least a comparator 1-1, a timer 1-2, a calendar 1-3, and a register section 1-4, and controls the air conditioner by referring to the information set in the register section 1-4. 2 is a disk that controls the start-up, etc., and holds various information such as data for calculating the advance time of the air conditioner, such as data for weekdays, advance schedule for weekdays, advance schedule for holidays, and indoor target temperature; Read/write control is performed by the disk control device 21.

Reference numeral 3 denotes a memory, in which, for example, holiday data read out from the disk 2, various advance patterns, etc. are stored. 4 is a setting panel, which allows the operator to calculate the advance time of the air conditioner and set the target temperature. Settings etc. are done manually.

5A, 5B-5X are air conditioners, each air conditioner 5A,
The air conditioners 513- are each controlled from the CPUI by an air conditioner interface 5-1.

6A, 6B, -6X are sensors, and each air conditioner 5A,
5B and -5X, each sensor 6A and sensor 6B- are connected to the sensor interface 6.
-1 is controlled from the CPUI. 7 is a printer for printing the operating status, temperature status, etc.

For example, the holiday data stored on disk 2 is as follows:
The information is entered in the format shown in FIG. That is, as shown in Figure 4(a), data is shown for each month of holidays from January to December, and as shown in Figure 4(b), data for each month is shown for days from the 1st to December. The day before the 31st is a holiday is designated by two words of bits, with the designated bit being 1 and the others being 0.

Figure 5 shows an example of a pattern in which holidays are brought in advance.
The holiday light shown in FIG. 5(a) is created based on the pattern data as shown in pattern M1 shown in FIG. 5(b). The pattern data for this holiday is, for example, determined by experiment or obtained empirically, and includes an advance time y1 (for example, y+ = 10 minutes) for a certain temperature difference X+ (for example, xl-5°C), The maximum temperature difference xo, which is the limit of the air conditioner's capacity (e.g. x, -10°C)
and an advance time y0 (for example, '1o=25 minutes).

In addition, in FIG. 5(b), the graph M2 indicated by the dotted line
“ indicates advance slam for weekdays under the same conditions,
For example, for χ = 5°C, the advance time is y = 7 minutes.

Next, an example in which the room use start time is set to 8:00 a.m. on September 4th when September 2nd and 3rd are holidays will be explained with reference to FIGS. 2 and 3.

(1) First, when the operator sets the indoor target temperature (for example, 24°C) from the setting panel 4 at 5 a.m. on September 4th, the CPU
I stores the stored holiday data from memory 3 into register REGo of register section 1-4 (3rd
(see Figure I).

(IT) The CPU compares and analyzes the date on the calendar 1-3 and the holiday data using the comparator 1-1, and when it determines that September 4th is the end of the holiday, it transfers the data to the disk 2 via the memory 3. For the day off, the pattern M1 is extracted in advance (see Figure 3).

(I[[) Next, the CPU 1 detects, for example, an empty J by the sensor 6A.
Measure the indoor temperature near Iil15A, for example 30°C,
A temperature difference of 6°C between this and the indoor target temperature, for example 24°C, is calculated. This temperature difference and the extracted holiday light are brought forward pattern M
1 (Figure 5 (b)), the advance time is calculated to be 13 minutes,
The starting time To=1:47 of the air conditioner 5A is calculated. The start time To and the empty m11 number 5A are stored in the memory 3.

In the same manner, the startup time and air conditioner number of other air conditioners to be managed by the CPU 1 are set in the memory 3 as shown in Figure 2 (see ■ in Figure 3). 1-4 register REG
Comparator 1 compares the startup time set in I with timer 1-2.
-1, and at a predetermined time, for example, To=7:47, the air conditioner 1!5A is read out from the register RE G 1 of the register section 1-4, and a command is given to start up the air conditioner 5A.

The air conditioner interface 5-1 decodes the command from the CPUI, controls the activation of the selected air conditioner 1!5A, and activates the air conditioner 115A.

The other air conditioners 115B and below operate in the same manner (3rd
(See figure ■).

In the above explanation, the case where data is referred to on holidays is explained, but of course the case is not limited to this only. For example, a holiday pattern is memorized, and data is calculated from this on holidays and evenings. Good too.

〔Effect of the invention〕

As in the present invention, when determining the activation time of the sky aia, in addition to weekday data, by applying the data for holidays and the early morning holiday pattern, it is possible to efficiently set the early start time even after holidays, and when the room starts to be used. This makes it possible to bring the indoor temperature closer to the indoor target temperature.
