In addition, when the amount of heat is insufficient for the load, at night the hot water temperature is lower than the hot water setting temperature, and the necessary minimum auxiliary heating operation is controlled, and during cooling, the cold storage operation, which is advantageous at night, is controlled at a predetermined low setting. carried out at a cold water temperature of

で全日の冷房負荷を賄うことと同じである。 Conventionally, solar heat pump type air conditioners heat the collector, which serves as an evaporator, to increase the evaporation effect when the outside air temperature is high in the daytime during heating, and increase the evaporation effect when the outside air temperature is low at night during cooling. The water is cooled by a heat collector that serves as a condenser to enhance the condensation effect, and the hot water and cold water obtained by the water cooler/heater are stored in a heat storage tank. The cold/hot water operation time for storing in the heat storage tank is programmed and switched from winter heating operation to daytime operation by a program timer, and programmed and switched to summer cooling operation and night operation. ,
Operation was switched between winter and summer using a program timer. However, with this switching method, since the operation is switched temporally between daytime and nighttime, covering the entire day's heating load with only daytime operation during heating requires a large heat storage tank itself, and solar heat The disadvantage is that the capacity of the heat pump type air conditioner used must also be increased. This is also the same as covering the whole day's cooling load only by operating at night during cooling.

のである。 To explain these in more detail, for example:
As shown in FIG. 3, the program timer 12 is
If you set the cold storage time from 7pm to 7pm during cooling, the auxiliary cooling operation time from 7pm to 7pm, and vice versa during heating, for example, when you set the operation switch 15 to the cooling position during summer cooling, contact a of the chilled water temperature regulator 24 , b, and on the other hand, the electromagnetic switch 14 is energized and energized from the cooling side of the operation switch and one end of the program timer 12, and the contact 21 for switching between cooling and heating is reversed to the cooling side, and the program timer 12 is activated. 7
When the time comes and it turns on, one end becomes the electromagnetic switch 13.
Then, the other end is energized and energized by power supply A, and contact 2
2 and 23 are reversed to the dotted line position. When the dotted line position is reached, the contact a of the auxiliary cooling operation thermostat of the chilled water temperature regulator 24 is energized, and the chilled water in the heat storage tank starts flowing.
Contact a opens when the temperature reaches 10°C, and closes when the temperature reaches 13°C, starting and stopping the compressor during operating hours between 7:00 and 19:00. At 7:00 p.m., the cold storage period continues until 7:00 a.m. When the program timer 12 is turned off and the excitation of the electromagnetic switch 13 is cut off, the contacts 22 and 23 switch to the solid line position.
The cold water temperature regulator 24 energizes contact b of the cold storage thermostat. By energizing contact b, cold storage begins during the heat storage period, and contact b opens at 5°C and closes at 8°C, increasing operating efficiency and storing cold when the outside air temperature is low at night during cooling. During daytime, when the outside temperature is high, auxiliary cooling operation is performed only when the amount of cool storage is insufficient. This is also reversed during heating; for example,
The heat storage time set by the program timer 12 during heating and the usage time period are the same as those during cooling. Therefore, when the heating operation switch 15 is set to the heating position, it is connected to the contacts c and d of the hot water temperature regulator 25, while the electromagnetic switch 14 is de-energized and the contact 21 for switching between cooling and heating is energized to the heating side. At the same time, the program timer 12 is turned on and one end is connected to the electromagnetic switch 1.
3, the other end is energized by power supply A, and when contacts 22 and 23 are set to the dotted line position, hot water temperature regulator 2
Contact d of the heat storage thermostat No. 5 is energized,
Heat storage operation is performed. In other words, the time period is from 7 a.m. to 7 p.m., and the contact point d is 55.
It opens at ℃ and closes at 52℃. Next, at 7pm, the program timer 12 is turned off, the electromagnetic switch 13 is de-energized, the contacts 22 and 23 are in the solid line position, and the contact c of the thermostat for auxiliary heating operation is turned off.
energized, contact c closes at 47°C and opens at 50°C, and auxiliary heating operation is performed during heating during the auxiliary heating operation period from 7:00 pm at night to 7:00 am.

ーとなるなどの効果を発揮するものである。 As described above, according to the present invention, a heat pump type air conditioner that uses solar heat is operated to obtain a high temperature during heating and during the day when the outside temperature is high, storing heat, and reducing the outside temperature at night. When the temperature is low, auxiliary heating operation is performed only when the amount of heat storage is insufficient, and the reverse operation is performed during cooling, so that the main operation is daytime operation, which is advantageous for heating, and nighttime operation, which is advantageous when cooling. Because it becomes like that,
The efficiency of the entire system can be increased and the size of the heat storage tank can also be reduced. In addition, since the program timer automatically switches between cold storage heat operation and auxiliary operation, running costs are low and energy savings are achieved.
