Title:
HEAT PUMP SYSTEM AND METHOD FOR ACHIEVING EFFICIENT EVAPORATION USING GEOTHERMAL WELL
Document Type and Number:
WIPO Patent Application WO/2022/022750
Kind Code:
A1
Abstract:
Disclosed are a heat pump system and method for achieving efficient evaporation using a geothermal well, relating to the field of geothermal energy development. Said system comprises a stepped underground evaporator, a compressor, a condenser, a liquid storage tank, and a throttle valve. The underground evaporator comprises an inner pipe and an outer pipe, the inner pipe is designed as a multi-segment structure, each segment is comprised of a gas flow guide pipe, a baffle plate and a seepage hole, and under the effect of this structure, a liquid working medium flowing into the underground evaporator flows downward against an inner wall of the outer pipe, absorbs heat from underground rock mass and is gasified into a gaseous working medium to flow upward to the ground. Compared with the prior art, the underground evaporator designed according to the present invention does not produce gas-liquid entrainment and liquid accumulation effects, and can achieve efficient evaporation of the liquid working medium using a geothermal well, without the need of water pump circulation for heat supply, such that the required ground equipment of the heat pump system is simplified, and the operating efficiency of the heat pump system can be significantly increased, thereby increasing the overall economical efficiency of the ground source heat pump system.
