Domestic underfloor heating is a form of water heat pump. It uses water and underground energy (ground water, soil or surface water) to exchange heat and cold as the cold and heat source of the water heat pump. heat from underground energy is used to provide indoor heating. At this time, the ground can be used as a "heat source" in summer, internal heat is extracted and released into groundwater, soil or surface. the water. At this time, the ground can be used as a “cold spring”.
The domestic floor heating and cooling system is mainly divided into three parts: geothermal energy outdoor heat exchange system, water source heat pump unit and the terminal indoor heating and air conditioning system. There are two main types of water heat pumps: water-to-water type or water-to-air type. The transThe heat exchange between the three systems is based on the heat transfer fluid water or air. The heat transfer fluid between the water heat pump and the underground energy is water, and the heat transfer fluid with the building heating and air conditioning terminal can be water or. air
