Ground source heat pump pipe heating pipe heating pipe Yanggu Yongsheng

Suitable fluid medium: Due to the high ground temperature in the southern region, the water inlet temperature of underground pipes in winter is above ℃, so water is often used as the working fluid. In the northern region, the ground temperature is low in winter, and the water inlet temperature of underground pipes is generally lower than ℃, so antifreeze is generally required. (① Salt solution - calcium chloride and sodium chloride aqueous solution ② Ethylene glycol aqueous solution ③ Alcohol aqueous solution, etc.). Related knowledge: Ground source heat pump is a high-efficiency and energy-saving air conditioning system that utilizes shallow underground geothermal resources (also called ground energy, including underground water, soil or surface water, etc.) to provide both heating and cooling. By inputting a small amount of high-grade energy (such as electricity), the ground source heat pump realizes the transfer of low-temperature heat energy to high-temperature locations, thereby providing heating and cooling for the indoor ends of the building. It can also provide domestic hot water, which is safe, comfortable, energy-saving, environmentally friendly, Economical, efficient and recyclable.
