Title:
DOUBLE-STRUCTURE WATER SOURCE HEAT PUMP HEAT EXCHANGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/032359
Kind Code:
A1
Abstract:
The present invention relates to a heat exchange system, in particular to a double-structure water source heat pump heat exchange system, comprising a compressor, a water source heat exchanger, an expansion valve, and an air source heat exchanger which are sequentially connected and form a cycle. The water source heat exchanger comprises a refrigerant pipe allowing a refrigerant to pass through, and a water pipe sleeved and fixed on the outside of the refrigerant pipe and allowing water to pass through, and the refrigerant and the water implement counterflow heat exchange in the water source heat exchanger; pipe openings at two ends of the refrigerant pipe are respectively connected to the compressor and the expansion valve; the refrigerant pipe comprises a thick pipe and a thin pipe connected to each other; a pipe opening of the thick pipe is connected to the compressor, and a pipe opening of the thin pipe is connected to the expansion valve; the refrigerant implements sensible heat exchange in the thick pipe, and is subjected to a phase change in the thin pipe; two ends of the water pipe are respectively provided with a water source heat exchanger water inlet and a water source heat exchanger water outlet; and water enters the water pipe via the water source heat exchanger water inlet, and leaves, after heat exchange with the refrigerant, the water pipe via the water source heat exchanger water outlet. Compared with the prior art, the present invention can effectively improve the energy efficiency ratio of the heat exchange system.
