Air source heat pump is a new type of heating equipment, its biggest feature is energy saving, so how does it heat? Now we will introduce the heating principle for you.
In fact, the principle of air source heat pump heating is easy to understand. It is one of the heat pumps. The so-called air source is to absorb low-grade heat energy in the air, and then work through electric energy to get the heat source we need.
The four components of air source heat pump are compressor, condenser, throttling device and evaporator. After the low-pressure gaseous working medium enters the compressor, it is compressed into high-temperature and high-pressure gas. At this time, the boiling point of the working medium rises with the increase of pressure. The working medium with high boiling point enters the condenser and begins to liquefy. The working medium releases heat, and the working medium that loses heat becomes liquid. Then it enters the evaporator after passing through the throttling device. The throttling device reduces the pressure of the working medium The mass begins to evaporate again in the evaporator. At this time, the working medium absorbs heat and becomes low-pressure gas. Then it enters the compressor, and the refrigerant circulates all the time. This is the principle of heat pump cycle and the principle of air heating. The heat pump cycle has the following four steps:
1: Compressor compresses to make low temperature low pressure compression high temperature high pressure gas
2: Condensation isobaric process: high temperature and high pressure gas - heat release - medium temperature and high pressure liquid.
3: Throttling isoenthalpy process: medium temperature and high pressure liquid throttling low temperature and low pressure gas liquid mixture
4: Evaporation isobaric process: low temperature and low pressure gas liquid mixture endothermic low temperature and low pressure gas
The above is our first detailed introduction about the principle of air source heat pump heating, through understanding, do you have a new understanding of heat pump heating? Of course, in addition to heating, air source heat pump can also provide us with free domestic hot water, which can also be used as air conditioning in summer.
