All shallow cryogenic heat pumps are collectively called ground source heat pumps
Ground source heat pump is divided into open system and closed system.
By ground source heat pump, you mean ground source.
The difference between "ground source" and "water source" is mainly due to different media and different design and construction methods.
Ground source heat pump (GSHP) is also a kind of closed system, which mainly lays ground coupling pipe around the building and completes heat exchange between the flow medium in the closed pipe and the inside of the building.
Water source heat pump (WSHP) is a kind of open system. Groundwater or surface water extracts heat through heat exchanger.
Ground source heat pump collects heat from soil by buried pipe. The principle of ground water source heat pump collects heat from groundwater is similar. The actual design temperature, refrigerant and valve components are different, because the groundwater temperature is higher, it can be directly used as refrigerant. However, the temperature of the effluent from buried pipes is low, and it is often lower than zero. Therefore, ethylene glycol solution is often used as a refrigerant. The concentration of ethylene glycol depends on the lowest effluent temperature. The principle is the same, the way to get heat source is different.
Water source heat pump (WSHP) is to take groundwater directly for heat transfer or cooling during well drilling.
Ground source heat pump is to bury many pipelines underground, and then fill the pipeline with water or antifreeze for replacement.
Thermal medium, through the medium in the pipeline cycle to absorb underground heat or cold.
C. Other differences:
Ground source heat pump (GSHP) is an underground closed system, and water source is an open underground system. The water source is limited by the government, and the long-term stability of the groundwater source is also affected. Sources are relatively stable. The connection is that they all share the same refrigeration (heat) principle, but use different media.
Ground source heat pump includes ground source heat pump and water source heat pump water source heat pump including surface water and ground water source heat pump
Simply speaking, ground source heat pump is to extract the temperature of underground soil source, water source heat pump is to extract the temperature of groundwater, and then to achieve heating or refrigeration through the combination of machines, ground source heat pump is much more expensive than small source heat pump, so generally as long as a region is rich in groundwater, water source heat pump will be used.
