With the development of economy and the improvement of people's living standard, the heating and air conditioning of public buildings and residences has become a universal demand.
In the refrigeration state, the compressor in the ground source heat pump unit works on the refrigerant to carry out the steam liquid conversion cycle. The refrigerant / air heat exchanger in the evaporation of refrigerant to air circulation carried by the heat absorption to the refrigerant, and then through the condensation of refrigerant / water heat exchanger refrigerant in the refrigerant circulation at the same time, by water circulating the refrigerant carries the heat absorbed by water circulation transfer finally to groundwater or soil. In the process of constant heat transfer to the ground, the air - to - air heat exchanger is used to cool the room with cold air below 13 degrees.
In the heating state, the compressor in the ground source heat pump unit works on the refrigerant and changes the direction of the refrigerant flow through the four way valve. By water absorption cycle of underground soil or groundwater in the heat by refrigerant / water heat exchanger in the evaporation of refrigerant, the heat absorption in the water circulation to the refrigerant, and then through the condensation of refrigerant / air heat exchanger refrigerant in the refrigerant circulation at the same time, the air circulation of the refrigerant the heat brought by absorption. Ground source heat pump to the underground heat continuously transferred to the interior of the process, more than 35 degrees Celsius in the form of hot air heating.
The working principle of ground source heat pump in the circulation of the entire air conditioning system, system and air source heat pump, water pump is not much difference, the difference is different in the cold and heat source of heat pump, the heat generated by the condenser (cold) with different heat transfer mode of outdoor environment. Ground source heat pump is the use of water and energy (soil or groundwater, surface water) for cold and heat exchange as cold and heat source heat pump in winter, and the heat to be able to "take out", the supply of indoor heating, this time to "heat"; the summer indoor heat out, released into the soil or groundwater, surface water, the cold source for "".
