Ground source heat pump air conditioning 

Ground source heat pump air conditioning Ground source heat pump air conditioning is a kind of air conditioning system using geothermal energy as a cold and heat source, combined with the principle of heat pump to achieve efficient heating and refrigeration. Its core idea is to use the constant temperature characteristics of underground soil, groundwater or surface water to provide buildings with a comfortable environment warm in winter and cool in summer.

Operating principle of ground source heat pump air conditioning:

Winter heating stage: the ground source heat pump unit extracts the heat from the underground constant temperature layer, through a medium (usually water) in the underground heat exchanger (such as vertical buried pipe or horizontal buried pipe system) circulation flow, the heat is extracted and raised to the appropriate temperature, used for indoor heating or supply of domestic hot water.

Summer refrigeration stage: the opposite process will occur, the ground source heat pump will release the excess heat into the underground soil through the same set of heat exchange system, because the underground temperature is relatively stable all year round, so it can effectively absorb the heat, and keep the room cool.

Main equipment of the system: the main terminal part, chiller; air conditioning circulating pump, cooling water circulating pump (submersible pump), air conditioning area (main equipment of air conditioning end), full air air conditioning treatment unit (including fresh air unit), fan coil. Frozen water in summer (7 / 12℃) and hot water in winter (45 / 40℃)
