Next, the operation of the above configuration will be described with reference to the flowchart of FIG. During the cooling operation, the refrigerant discharged from the compressor 1 flows in the direction of the solid line arrow in FIG. 2, a cooling cycle is formed, and the outdoor heat exchanger 3 becomes the condenser and the indoor heat exchanger 5
Functions as an evaporator. The interior of the room is cooled by the heat exchange between the refrigerant and the room air in the room heat exchanger 5.

During operation, the room temperature T is measured by the room temperature sensor 31.
a is detected (step 101). Further, the outside air temperature sensor 42 on the outdoor side detects the outside air temperature, the wind direction / wind speed sensor 43 detects the wind direction and wind speed, and the atmospheric pressure sensor 44 detects the atmospheric pressure. By comparing these detection results with prestored weather reference data, The weather in the specific area where the air conditioner is installed is predicted (step 102).

Based on the predicted weather and the output data (weekdays, holidays, days of the week, hours) of the calendar / clock unit 32, the power demand in the power supply area of the power plant is predicted (step 103).

For example, when conditions such as fine weather, high outside temperature, no wind, strong sunlight, holidays, and high school baseball summer tournament overlap, air conditioners at home and at work are fully operated, and watching TV is possible. In addition, power demand may peak.

When the predicted power demand is equal to or higher than the predetermined value close to the peak, it is determined that the regulation of the power consumption P of the air conditioner is necessary (YES in step 104), the next control is executed. .

First, at the time of start-up when a predetermined time has not yet passed from the start of operation (step 105), a temperature lower than the indoor temperature Ta by a predetermined value, for example 3 ° C., is set as the target set temperature Ts (step 106).

As the target set temperature Ts, the remote controller 50
The input value from is stored in advance in the memory in the indoor control unit 30, but in this case, it is not used and a value lower than the indoor temperature Ta by 3 ° C. is forcibly set as described above.

As will be described later, the capacity of the compressor 1 is controlled according to the difference ΔT between the room temperature Ta and the target set temperature Ts, and the room temperature Ta and the target set temperature Ts are the same as when starting. In a situation where there is a large difference, the compressor 1 will operate at maximum capacity. This is contrary to the regulation of the power consumption P, and as shown in FIG. 4, the power consumption P reaches the maximum rating Pmax. In order to prevent such a situation, a value lower than the indoor temperature Ta by 3 ° C. is set as the target set temperature T.
s.

In this case, the fact that the power consumption P is regulated is displayed on the display device 33 (step 107). Then, the room temperature Ta and the target set temperature Ts which is 3 ° C. lower than that
The difference ΔT (= 3 ° C.) from the temperature difference is calculated (step 108), and the operating frequency (output frequency of the inverter circuit 46) F of the compressor 1 is controlled according to the temperature difference ΔT (step 10).
9).

Therefore, the capacity of the compressor 1 is limited to a value lower than that in the normal state, and the power consumption P is regulated to the predetermined value P ₃ . By this regulation, the power demand in the supply area of the electric power company can be relaxed.

On the other hand, when the regulation is required (step 104
YES), and if the engine is in the steady operation after startup, the time count t is started (step 110). Until the time count t reaches the predetermined time t ₁ (step 11
1 YES), a predetermined value (ΔTs
+ Α) is added to set a new target set temperature Ts (step 112).

When the time count t reaches the predetermined time t ₁ (NO in step 111), a predetermined value ΔTs is added to the original target set temperature Ts to set a new target set temperature Ts (step 113).

The fact that the power consumption P is regulated is displayed on the display device 33 (step 107). Then, the difference ΔT between the room temperature Ta and the corrected target set temperature Ts
(= Ta-Ts) is obtained (step 108), and the operating frequency (output frequency of the inverter circuit 46) F of the compressor 1 is controlled according to the temperature difference ΔT (step 10).
9).

Target set temperature Ts and power consumption P in this case
The relationship with is shown in FIG. Thus, the target set temperature Ts
Is shifted to a low load side by a predetermined value, the compressor 1
Power is reduced and power consumption P is lower than normal P _2.
Regulated to ₁ . By this regulation, the power demand in the supply area of the electric power company can be relaxed.

In this case, the predetermined value ΔTs is set to a different value according to the predicted power demand. That is, the greater the power demand, the larger the predetermined value ΔTs is set. In this way, the power consumption P is not regulated unconditionally, but only the required amount is regulated so that the reduction in comfort is minimized.

The predetermined value α may be fixed or variable. At the first predetermined time t ₁ , the transition width to the low load side is increased by this predetermined value α, but this is to increase the degree to which the resident feels uncomfortable at first and then to make the discomfort later. This is for fading.

Since the power consumption P is controlled by correcting the target set temperature Ts, the air conditioning can be regulated while the air conditioning is continued. Therefore, it is possible to reduce the power demand while ensuring a certain degree of comfort. . Moreover, power consumption P
Since the resident is informed of the regulation of No. 3 by the display of the display 33, the resident can easily know that the cause is the alleviation of the power demand even if the comfort is lowered, and the power company and the manufacturer can It is possible to avoid confusion such as flooding of queries.

In particular, since the air conditioner side is designed to automatically reduce the demand for electric power, troublesome arrangements with the electric power company and system construction are completely unnecessary, and communication with the electric power company is unnecessary. Therefore, the cost of equipment such as communication equipment will not soar.

Next, a second embodiment of the present invention will be described. Here, the power consumption P is regulated by lowering the operating frequency F. The operation is shown in FIG. Other configurations are the same as those in the first embodiment.

During operation, the room temperature sensor 31 detects the room temperature T.
a is detected (step 201). The difference ΔT (= T) between the room temperature Ta and the target temperature Ts set by the remote controller 50.
a-Ts) is calculated (step 202), and the temperature difference Δ
A target value Ft of the operating frequency F is obtained according to T (step 203).

The outdoor air temperature sensor 42 on the outdoor side
Wind direction / speed sensor 43 for wind direction / speed, pressure sensor 4
Atmospheric pressure is detected in step 4, and the weather in the specific area where the air conditioner is installed is predicted by comparing the detection results with the weather reference data stored in advance (step 204).

Based on the predicted weather and the output data (weekdays, holidays, days of the week, hours) of the calendar / clock unit 32, the power demand in the power supply area of the power plant is predicted (step 205).

When the predicted power demand is equal to or higher than the predetermined value close to the peak, it is determined that the regulation of the power consumption P of the air conditioner is necessary (YES in step 206), and the calculated target value Ft is obtained. Is reduced by a predetermined value ΔF (step 20)
7). Then, the actual operating frequency F is set to the corrected target value Ft (step 208).

Therefore, the capacity of the compressor 1 is limited to a level lower than that in normal times, and the power consumption P is regulated. By this regulation, the power demand in the supply area of the electric power company can be relaxed.

In this case, the fact that the power consumption P is regulated is displayed on the display device 33 (step 209). The predetermined value ΔF is set to a different value according to the predicted magnitude of power demand. That is, the larger the power demand is, the larger the predetermined value ΔF is set. In this way, the power consumption P is not regulated unconditionally, but only the required amount is regulated so that the reduction in comfort is minimized.

Since the power consumption P is controlled by the reduction of the operating frequency F, the regulation can be performed while the air conditioning is continued, so that it is possible to relax the power demand while ensuring a certain degree of comfort.

When the power consumption P is regulated by correcting the target set temperature Ts, the difference between the indoor temperature Ta and the target set temperature Ts is considerably large, and even if the target set temperature Ts is corrected, the capacity of the compressor 1 is large. Therefore, the regulation of the power consumption P may become insufficient. On the other hand, the operating frequency F
It is possible to reliably regulate the power consumption P regardless of the load condition by directly reducing

Next explained is the third embodiment of the invention. Here, the power consumption P is regulated by reducing the maximum allowable value Imax of the input current I to the air conditioner. The operation is shown in FIG. Other configurations are the same as those in the first embodiment.

The allowable maximum value Imax of the input current I for the air conditioner is stored in advance and is read (step 301). Indoor temperature sensor 31 during operation
The room temperature Ta is detected at (step 302). The difference ΔT (= Ta-Ts) between the indoor temperature Ta and the target set temperature Ts by the remote controller 50 is calculated (step 303),
A target value Ft of the operating frequency F is obtained according to the temperature difference ΔT (step 304).

The outdoor air temperature sensor 42 on the outdoor side
Wind direction / speed sensor 43 for wind direction / speed, pressure sensor 4
Atmospheric pressure is detected at 4 respectively, and the weather of the specific area where the air conditioner is installed is predicted by comparing the detection results with the weather reference data stored in advance (step 305).

Based on the predicted weather and the output data (weekdays, holidays, days of the week, hours) of the calendar / clock unit 32, the power demand in the power supply area of the power plant is predicted (step 306).

When the predicted power demand is equal to or higher than the predetermined value close to the peak, it is judged that the regulation of the power consumption P of the air conditioner is necessary (YES in step 307), and the read maximum allowable value is read. Imax is reduced by a predetermined value ΔI (step 308).

The actual input current I is detected by the current sensor 36, and it is compared with the corrected maximum allowable value Imax (step 309). Input current I is the maximum allowable value Imax
Is equal to or greater than (in step 309
YES), the obtained target value Ft is reduced by a predetermined value ΔF (step 310). Then, the corrected target value F
The actual operating frequency F is set to t (step 311).
).

Therefore, the capacity of the compressor 1 is limited to a value lower than that of the normal time, and the power consumption P is regulated. By this regulation, the power demand in the supply area of the electric power company can be relaxed.

In this case, the fact that the power consumption P is regulated is displayed on the display device 33 (step 312). The predetermined value ΔF is set to a different value according to the predicted magnitude of power demand. That is, the larger the power demand is, the larger the predetermined value ΔF is set. In this way, the power consumption P is not regulated unconditionally, but only the required amount is regulated so that the reduction in comfort is minimized.

Since the power consumption P is controlled by reducing the allowable maximum value Imax, the regulation can be performed while the air conditioning is continued, so that it is possible to relax the power demand while ensuring a certain degree of comfort. .

[0069]

As described above, according to the present invention, the air conditioner of the first invention judges weekdays, holidays, days of the week, and time, and from this and the outside temperature, the inside of the supply area of the power plant is judged. Since the power demand is predicted and the power consumption of the air conditioner is regulated when the power demand is equal to or higher than a predetermined value,
Electricity demand in the supply area of the electric power company can be mitigated without requiring complicated arrangements and system construction with the electric power company, without causing a rise in equipment costs, and without causing discomfort or confusion to residents. .

In the air conditioner according to the third aspect of the invention, the amount of regulation on power consumption is changed according to the predicted magnitude of power demand, so the comfort level is reduced due to the regulation of power consumption. It can be kept to a minimum.

In the air conditioner of the fourth aspect of the present invention, the power consumption is regulated by shifting the target set temperature to the low load side. Therefore, the regulation can be carried out while the air conditioning is continued, and therefore, to a certain extent. It will be possible to relax electricity demand while ensuring a comfortable feeling.

In the air conditioner of the fifth aspect of the present invention, when the target set temperature is shifted to the low load side, the transition width is temporarily increased for a predetermined time. Can be diluted as much as possible.

In the air conditioner of the sixth aspect of the present invention, when the target set temperature shifts to the low load side, the target set temperature is set to a value such that the compression functional force does not become maximum within a predetermined time from the start of operation. Since it is set, it is possible to surely reduce the power demand even at the start of operation.

Since the air conditioner of the seventh aspect of the present invention informs that the power consumption is regulated, even if the comfort is deteriorated, the resident is to say that the cause is to alleviate the power demand. It is easy to know and avoid confusion such as flooding inquiries to electric power companies and manufacturers.

Since the air conditioner of the eighth invention regulates the power consumption by lowering the operating frequency of the compressor, it is possible to reliably regulate the power consumption regardless of the load conditions.

Since the air conditioner of the ninth invention regulates the power consumption by lowering the allowable maximum value of the input current, it is possible to regulate while continuing air conditioning.
Therefore, it is possible to reduce the demand for electric power while ensuring a certain level of comfort.
