Compared with traditional air conditioning, solar air conditioning has good seasonal matching and can realize building energy supply system integrated with buildings, so it has received widespread attention in the new energy industry.

[0003] Solar air conditioners include solar photovoltaic air conditioners and solar thermal air conditioners. Solar photovoltaic air conditioners are traditional air conditioners with solar photovoltaic panels added to them, which means that the traditional air conditioners are driven by the electricity generated by external solar photovoltaic panels. Solar thermal air conditioners convert solar energy into thermal energy through solar collectors, and then drive absorption air conditioners through the thermal energy.

[0004] At present, patent number CN101498513A discloses an integrated flat-plate solar heat pump water heating device, whose collector can act as an evaporator, but only has a hot water making function and no cooling function, which greatly reduces the practicality of the collector.

The working port A1 of the first electromagnetic reversing valve 4 is connected to the outlet of the solar thermal collector 19 through the second pipeline 18. The solar thermal collector 19 can heat cold water into hot water. The heated hot water is sent to the second heat exchange channel 7 through the first electromagnetic reversing valve 4. Then, the second heat exchange channel 7 exchanges heat with the first heat exchange channel 6, thereby providing a heat source for the first heat exchange channel 6. The working port A2 of the second electromagnetic reversing valve 5 is connected to the inlet of the water storage tank 20 through the second pipe 18, and the outlet of the water storage tank 20 is connected to the inlet of the solar collector 19 through the second pipe 18 via the second circulation pump 21.

The heater 22 is installed in the water storage tank 20 for auxiliary heating when the solar collector 19 is not heating enough.

[0036] The second water replenishment valve 23 is connected to the water storage tank 20 through the second pipe 18. By setting the second water replenishment valve 23, cooling water can be added to the water storage tank 20.

By switching the third electromagnetic reversing valve 29, the excess cooling water in the second heat exchange channel 7 can be discharged to the recovery drum 31 before providing a cold source.

[0039] The implementation principle of a high-efficiency integrated air conditioning system in the embodiment of the present application is:

[0040] When it is necessary to provide heat to the air conditioner body 1, the cooling circuit does not work, the valve core of the first electromagnetic reversing valve 4 is moved up, and the outlet P of the first electromagnetic reversing valve 4 is connected to the working port A1, the valve core of the second electromagnetic reversing valve 5 is moved up, and the inlet T2 of the second reversing valve is connected to the working port A2, and the valve core of the third electromagnetic reversing valve 29 is moved up, and the inlet T3 of the third reversing valve is connected to the working port A3. After that, the heating circuit works, and the cooling water heated in the solar collector 19 can be sent to the second heat exchange channel 7 and thermally interact with the first heat exchange channel 6, thereby providing a heat source. The first heat exchange channel 6 can heat and heat the water entering the air conditioner body 1.

[0041] When the heating effect of the solar thermal collector 19 is poor due to weather reasons, the cooling water in the water storage tank 20 can be heated by the heater 22 to ensure the effect of providing the heat source, and the heater 22 and the solar thermal collector 19 can work at the same time.

[0042] When cooling is required for the air conditioner body 1, the heating circuit does not work, the valve core of the first electromagnetic reversing valve 4 is moved down, and the outlet P of the first electromagnetic reversing valve 4 is connected to the working port B1, the valve core of the second electromagnetic reversing valve 5 is moved down, and the inlet T2 of the second reversing valve is connected to the working port B2, and the valve core of the third electromagnetic reversing valve 29 is moved down, and the inlet T3 of the third reversing valve is connected to the working port B3. The cooling water in the second heat exchange channel 7 is discharged into the recovery cylinder 31 through the third pipe 30. Then the valve core of the third electromagnetic reversing valve 29 is moved up, so that the inlet T3 of the third electromagnetic reversing valve 29 is connected to the working port A3. At this time, the cooling circuit works, and the cold carbon dioxide is pressurized and sent to the second heat exchange channel 7 through the first electromagnetic reversing valve 4 and heat exchanged with the first heat exchange channel 6, thereby providing a cold source. The first heat exchange channel 6 can cool the water entering the air conditioner body 1.

[0043] During the implementation of the high-efficiency integrated air-conditioning system, through the cooperation between the first electromagnetic reversing valve 4 and the second electromagnetic reversing valve 5, the plate heat exchanger 2 can provide a cold source or a heat source for the water circuit of the air-conditioning body 1, thereby realizing the functions of heating and cooling. In addition, it has a simple structure, low cost, and small space occupation, and can effectively save resources, thereby achieving the purpose of reducing costs and increasing efficiency.
