Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present invention and operation principle are described in detail:
Please refer to Fig. 1, Fig. 1 has the structural representation of coolant circulating system of heat recovery function according to an embodiment of the invention.
The coolant circulating system 10 with heat recovery function disclosed by the present invention can apply to the air-conditioning system of general office block, the refrigeration system of general freezer or other has the circulatory system of refrigerant phase transformation, but not as limit.Described refrigerant refers to, in air-conditioning system or refrigeration system internal circulation flow, to carry out absorbing heat and the flowing material of heat release, such as Refrigerantl2, is called for short R-12 or F-12, or HFC-134, referred to as R134A.
The coolant circulating system 10 with heat recovery function comprises a refrigerant circulation module and a heat recovery module 100.Refrigerant circulation module comprises compressor 200, evaporimeter 300 and the expansion gear 500 be connected, and specifically, refrigerant circulation module refers to the compressor, evaporimeter and the expansion gear that are usually arranged within air-conditioning system, refrigeration system etc.Heat recovery module 100 is connected between compressor 200 and expansion gear 500.Further, liquid refrigerants flows to evaporimeter 300 by expansion gear 500, and in time flowing through evaporimeter 300, absorbs a large amount of heat energy and become gaseous coolant.The gaseous coolant absorbing a large amount of heat energy then sequentially flows through compressor 200 and heat recovery module 100, and in time flowing through heat recovery module 100, discharges a large amount of heat energy and become liquid refrigerants, and heat recovery module 100 absorbs these heat energy and is used.Then, liquid refrigerants flow to expansion gear 500 by heat recovery module 100 again, to complete refrigerant circulation once, for this reason, the coolant circulating system 10 with heat recovery function that the present invention discloses, by arranging a heat recovery module in the circulatory system of air-conditioning system, refrigeration system etc., thus produced heat energy (used heat) is absorbed.
