Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Solar integration air-conditioner as shown in Figure 1, comprise indoor units 1 and outdoor unit 2, described outdoor unit 2 comprises compressor 21, solar thermal collection system 22, condenser 23 and the second water tank 24, be connected with condensed water discharge pipe 3 between indoor units 1 and outdoor unit 2, condensed water discharge pipe 3 is connected with the second water tank 24; Described solar thermal collection system 22 comprises the first water tank 222 and solar thermal collector 223, first water tank 222 is fixed with shell 26, electric heater unit 221 is provided with in first water tank 222, first water tank 222 is connected by pipeline with solar thermal collector 223, make the solar energy heating internal liquid that solar thermal collector 223 is drawn, fluid flow inside circulates, and heats the liquid in the first water tank 222, thus heating is from compressor 21 exhaust outlet cold-producing medium out.
Compressor 21 exhaust outlet of outdoor unit 2, the first water tank 222, condenser 23 are connected with three valve ports of cross valve 25 respectively, 4th valve port of described cross valve 25 is connected with triple valve 6, described triple valve 6 connects with the evaporimeter 11 of indoor units 2, and the compressor 21 of outdoor unit 2 is connected with the first water tank 222.
Be connected by the first pipeline 8 between described condenser 23 with the second water tank 24, specifically condenser 23 is connected with the import of the second water tank 24 by the first pipeline 8, the first pipeline 8 is provided with the first non-return valve 241.In second water tank 24, the head and the tail of heat exchanging pipe are connected to form a complete path respectively with the first pipeline 8, second pipeline 9.When controlling refrigeration, cold-producing medium enters the second water tank 24 heat exchange through the first non-return valve 241, and the cold-producing medium of heat carries out heat exchange.
Second water tank 24 is connected with refrigerating capillary 5 by the second pipeline 9, connected by the 3rd pipeline 10 between first pipeline 8 and the second pipeline 9, 3rd pipeline 10 is provided with the second non-return valve 242, namely on the triplate line (the second non-return valve 242 two ends and the 3rd pipeline are formed) before the second non-return valve 242 is arranged at the export pipeline of the second water tank 24, and communicate with the threeway on the pipeline of the first non-return valve 241 (being namely connected by threeway between the first pipeline 8 with the 3rd pipeline 10), when controlling refrigeration, cold-producing medium is not by the second non-return valve 242, and when heating, cold-producing medium does not form heat exchange stream by the second water tank 24.The i.e. cold water storage cistern of second water tank 24, arranges non-return valve bypass circulation for controlling: refrigerated medium cryogen, through cold water storage cistern heat exchange, heats cold-producing medium without cold water storage cistern heat exchange before cold water storage cistern.
