Air source heat pump floor heating-Air source heat pump floor heating characteristics: 1. Environmental protection and energy saving: judging from the energy used, the power of heating is free air heat energy, and only a little electricity is needed to absorb air heat energy, and the thermal efficiency is as high as 380%-600%. Compared with traditional energy sources, it not only has high thermal efficiency, but also avoids the emission of pollutants caused by the use of chemical energy sources, achieving the dual effects of energy saving and environmental protection. 2。 Safe and reliable: adopting physical working mode, the whole heating process will not produce toxic gas, and there will be no leakage accident during the separation of water and electricity. 3。 Low temperature operation: not affected by the environment, available all year round. Whether it is rainy or cold winter, the intelligent defrosting function of the heat pump unit can ensure the synthesis of high-temperature heat sources all day. ?
