What is the Principle of Air Source Heat Pump Heating?

The working principle of the air source heat pump heating system is to provide heating and cooling by absorbing heat from the air through the air source heat pump. Specifically, the air source heat pump absorbs low-grade heat energy from the air through the outdoor unit, then increases the temperature of the heat energy through the compression process, and finally transfers the high-temperature heat energy to the indoor heating equipment to achieve heating.

First of all, we must know that air source heat pump heating does not directly convert electrical energy into thermal energy. Instead, it uses an electric drive compressor to absorb heat from the air. The fin heat exchanger of the air source heat pump is filled with refrigerant, and the boiling point of the refrigerant is minus 51 degrees. So even if our ambient temperature is minus 35 degrees, there is still a temperature difference, and heat can still be extracted from the air.

Many people also say that air source heat pumps are air conditioners used and installed in reverse, but they are not.

In terms of user experience, the air conditioner uses a fluorine cycle. Whether it is cooling or heating, the fluorine system will absorb a lot of moisture from the air, which can easily cause dry air, hoarse throat, dry mouth and poor comfort. In heating mode, the air conditioner may not be able to provide enough heat at extremely low temperatures, resulting in uncomfortable indoor temperatures.

The air source heat pump cooler and heater first transfers heat through the refrigerant, and then relies on water to complete the heat exchange. This heat exchange method prevents the air source heat pump from producing dry air during the heating process, and keeps the indoor humidity appropriate. The air source heat pump uses water for heat exchange, and the air outlet is soft, making the indoor temperature more uniform, without the phenomenon of hot and cold, and the body feels more comfortable. The air source heat pump uses floor heating or radiators as the heat dissipation terminal in winter, and the comfort is incomparable to air conditioning.
