220V DC Inverter Air Source Heat Pump Low Noise Heating and Cooling
Quick Details
The variable frequency air source heat pump not only can not reduce the heating effect at low temperature, but also is more energy efficient. The air source heat pump can absorb low-temperature heat energy in the outdoor air by consuming a small amount of electric energy, compressing it into high-temperature heat energy through a compressor, and then heating the room. In a low temperature environment, the air source heat pump is also the same as the air conditioner, and the heating efficiency is also attenuated. In order to solve this problem, the variable frequency air source heat pump adopts a technology that allows the air source heat pump to not degrade at low temperatures. The jet boosting technology can be compressed or cascaded by 2 or more stages. It can reduce the compression ratio of each stage of the compressor, thereby improving the internal volume ratio efficiency of each stage, reducing the exhaust gas temperature, and effectively improving the heating performance at low temperatures.
