省エネルギーを可能にすることを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a heating and cooling system that combines an absorption cycle that operates using solar heat, waste heat, etc. as a heat source and a compression heat pump cycle, which includes a heat storage tank containing a heat exchanger for hot water supply. The purpose is to enable energy conservation throughout the year.

を介して暖房を行なうものがあつた。 Traditionally, air conditioning equipment that uses solar heat is
A heat medium such as water is circulated through a solar heat collector to extract heat as sensible heat. During the cooling period, this heat is supplied to the gas generator of the absorption chiller, which evaporates the refrigerant. On the other hand, during the heating season, there were some that used heat collected by solar collectors to heat the room via a heat medium.

必要である。 However, in this type of air-conditioning system, the generator of the absorption chiller is heated via hot water for cooling, which requires heated water that is at least 10°C higher than the temperature required by the generator, which also increases heat loss. Not only that, but additional auxiliary power such as a hot water circulation pump is required.

て凝縮器９に入り、ここで放熱し液化する。 First, the operation during cooling will be explained. When there is a sufficient heat source such as solar radiation, the concentrated solution containing a large amount of refrigerant sent by the solution pump 3 passes through the solution heat exchanger 2 and enters the heat collector generator 1 that uses solar heat or waste heat to heat it. to generate refrigerant gas,
The liquid becomes a dilute solution. The generated refrigerant gas is transferred to the passage 7.
However, since valve 6 is closed during cooling, it enters condenser 9 via valve 8, where it radiates heat and liquefies.

す。 The refrigerant liquefied in the condenser 9 is depressurized by the expansion valve 10 and becomes easily evaporated, and is then transferred to the first indoor heat exchanger 11.
It absorbs heat and evaporates. At this time, the indoor space etc. is cooled. The evaporated refrigerant enters the absorber 13 through the valve 12, exchanges heat with the concentrated solution from the generator 1 in the solution heat exchanger 2, and is absorbed by the dilute solution that returns to the absorber 13 through the throttle valve 4. The concentrated solution is sent again to the generator 1 by the solution pump 3, and the cycle is repeated.

には、圧縮式冷凍サイクルでのみ冷房を行なう。 Furthermore, when sufficient cooling output cannot be obtained due to an insufficient heat source such as solar radiation, the compressor 24 is operated and the second indoor heat exchanger 23 assists the cooling output. In this case, the refrigerant discharged from the compressor 24 is
8, the heat is radiated and condensed in the water-cooled heat exchanger 20 or the outdoor heat exchanger 26, the pressure is reduced in the expansion valve 22, and the air enters the indoor heat exchanger 23. The refrigerant that has entered the heat exchanger 23 absorbs heat and evaporates, cooling the indoor space. The refrigerant leaving the heat exchanger 23 passes through the four-way valve 28, enters the compressor 24, and repeats the cycle again. Note that when a sufficient heat source such as solar radiation is not available, cooling is performed only with a compression refrigeration cycle.

凝縮して暖房を行なう。 Next, the operation during heating will be explained. When a sufficient heat source such as solar radiation is available, the concentrated solution is sent to the heat collector generator 1 via the solution heat exchanger 2 by the pump 3, where a refrigerant gas is generated and becomes a dilute solution, which is then sent to the heat exchanger 2. It flows into the absorber 13 through the. On the other hand, the refrigerant gas generated by the generator 1 is transferred to the valve 8 and the valve 12.
When the valve 6 is closed and the valve 6 is opened, the water enters the absorber 13 through the passage 7, the valve 6, and the bypass passage 5. Absorber 13
At this time, the refrigerant gas and the dilute solution are mixed and dissolved to form a concentrated solution, and at this time, an amount of heat approximately equal to the amount of heat required to generate the refrigerant gas in the heat collecting generator 1 is released.
At this time, when cooling water flows in from the heat medium pipe 14, this water is heated in the absorber 13, and the water is heated at the outlet 1.
From 5, it flows out as warm water. Here, the water-cooled heat exchanger 20 of the compression heat pump cycle
Then, when the hot water obtained from the outlet 15 flows in with the pump 16 and the compressor 24 is operated, the heat released from the absorption type 13 is pumped up to the refrigerant vapor of the heat pump cycle via the hot water. heat exchanger 20
The refrigerant absorbed by the compressor 2 passes through the four-way valve 28.
4, where it is pressurized and heated and then transferred to the indoor heat exchanger 2.
3. The high temperature refrigerant radiates heat and condenses in the heat exchanger 23 to perform heating.

み上げ、前記と同様にして暖房を行なう。 In addition, when a heat source such as solar radiation or waste heat cannot be obtained, the absorption type cycle side is stopped, and if there is hot water in the heat storage tank, heat is pumped up from the heat exchanger 20, and when there is no hot water or the outside temperature is high. When it is more advantageous to use hot water, the outdoor heat exchanger 26 pumps up heat from the outside air and performs heating in the same manner as described above.

The hot water obtained in step 1 is stored in a heat storage tank 35 by passing through passages 32 and 33. When necessary, the hot water stored in the heat storage tank 35 is sent to the heat exchanger 20 by the pump 16 and used for heating, and the city water sent from the pipe 27 and the hot water heat exchanger 3
4 to heat the city water, and if necessary, the heated city water is heated by an auxiliary heat source 37 and used for hot water supply from a hot water supply circuit 36.
