The operation principle of the air conditioning system of the present embodiment will now be explained.
The refrigeration process of the primary refrigerating unit 1 is as follows: the low-pressure gaseous refrigerant is compressed into the high-pressure gaseous refrigerant under the compression action of the primary compressor 11, then the refrigerant is conveyed into the primary condenser 12 to exchange heat with water in the water pipe to enable the temperature of the water in the water pipe to rise, the temperature of the refrigerant in the primary condenser 12 is reduced and the refrigerant is condensed into high-pressure liquid, the high-pressure liquid refrigerant is converted into the low-pressure liquid refrigerant under the action of the expansion valve, then the refrigerant is conveyed into the primary evaporator 15 to exchange heat with the water in the water pipe, the temperature in the water pipe is reduced after heat exchange, meanwhile, the refrigerant absorbs heat and evaporates into low-pressure gaseous refrigerant, and then the refrigerant enters the primary compressor 11 again to complete one-time circulation.
The refrigerating process of the secondary refrigerating unit 5 is as follows: the low-pressure gaseous refrigerant is compressed into a high-pressure gaseous refrigerant under the compression action of the secondary compressor 51, then the refrigerant is conveyed into the secondary condenser 52 to exchange heat with water in the water pipe to increase the temperature of the water in the water pipe, the temperature of the refrigerant in the secondary condenser 52 is reduced and condensed into a high-pressure liquid state, the high-pressure liquid refrigerant is converted into a low-pressure liquid refrigerant under the action of an expansion valve, then the refrigerant is conveyed into the secondary evaporator 55 to fully exchange heat with air under the action of an air conditioning fan 56, the temperature of the air after heat exchange is reduced, meanwhile, the refrigerant absorbs heat and evaporates into a low-pressure gaseous state, and then the refrigerant enters the secondary compressor 51 again to complete one cycle.
The cooling tower 6 cools the high-temperature water generated by the first-stage condenser 12, the high-temperature water of the first-stage condenser 12 flows into the cooling tower 6 from the water inlet main pipe 63, and is assisted to dissipate heat through the cooling tower fan 62 and the filler 64, so that the temperature of the water is reduced and then flows back to the first-stage condenser 12 through the water outlet pipe 67. Since water loss such as evaporation occurs in the circulation circuit of the cooling tower 6-the primary condenser 12, the water in the circulation circuit can be supplemented by connecting the water supplementing tank 7 through the water supplementing pipe 65.
The water cooled by the first-stage evaporator 15 enters the cold storage tank 2 through a water pipe for transfer and temporary storage, is input into the second-stage condenser 52 through the water separator 3 to exchange heat with the refrigerant, and finally flows back into the first-stage evaporator 15 through the water collector 4 to be cooled again to complete one cycle. Since the water may leak in the circulation loop of the primary evaporator 15, the cold accumulation tank 2, the water separator 3, the secondary condenser 52, the water collector 4 and the primary evaporator 15, the water in the circulation loop can be supplemented by connecting the water supplementing tank 7 through the water supplementing pipe 65.
