Title:
GROUND SOURCE HEAT PUMP SYSTEM, INDOOR HEATING METHOD, AND INDOOR COOLING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/011258
Kind Code:
A1
Abstract:
A ground source heat pump system, an indoor heating method, and an indoor cooling method, the system comprising a ground source side heat exchange apparatus (100), a compressor (200), a four way valve (300), an indoor heat exchanger (400), and a first throttle apparatus (500); the ground source side heat exchange apparatus (100) comprises one or at least two parallel heat exchange pipes (110) buried vertically in the soil, the bottom of the heat exchange pipes (110) being provided with a reversible expansion valve (111). By means of directly exchanging heat between the refrigerant in the ground source heat pump system and the soil, the present ground source heat pump system eliminates the power loss caused by the need for circulating a cooling medium, such that the ground source heat pump system is more efficient and more energy saving; arranging a reversible expansion valve (111) in the bottom of a ground source side heat exchange pipe (110) effectively solves the problem of some of the refrigerant not going up when circulating to the bottom end of the heat exchange tube as a result of the bottom of the heat exchange pipe (110) being far away from the compressor (200), also saving the amount of refrigerant, improving the heat exchange efficiency of the ground source heat pump system, and reducing the initial investment costs and operating costs of the ground source heat pump system.
