Latest company news about What is air source heat pump?

    Air energy refers to the low-grade thermal energy contained in the air.As you all know, according to the second law of thermodynamics, it is impossible to transfer heat from a cold body to a hot body without causing other changes.Therefore, air cannot be used without consuming external energy.As a new category of water heater, air energy water heater uses a small amount of electric drive unit to work, absorb heat from the air and carry it to the water tank, so as to achieve the purpose of making hot water, to achieve the full use of low-grade heat energy in the air.

    So, the air can water heater specific operation process is how?To know the working principle of air water heater, first of all to understand the structure of air water heater.Air energy water heater is generally composed of four components: compressor, evaporator, condenser, expansion valve, its operation system is basically around these several large components to cycle work.To give you a better understanding of how the air energy water heater works, we have broken down the four components and their working process in detail.

    1. Evaporator as one of the four major heating components, the evaporator is mainly responsible for heat exchange, it absorbs heat energy from the air, and vaporizes and vaporizes the refrigerant (refrigerant) into the evaporator to achieve the purpose of absorbing energy in the air.After completing the heat exchange, the refrigerant comes to the compressor for the next cycle.

    2. Compressor as the "heart" of the heating system, the compressor can improve the low pressure gas to high pressure gas.The low temperature and low pressure refrigerant gas enters the compressor and is compressed into high temperature and high pressure refrigerant gas to provide power for the heating cycle, so as to realize the heating cycle.

    3. Condenser As the name suggests, condensers are capable of condensing gases into liquids.The high temperature and high pressure refrigerant gas enters the condenser, condenses into liquid, and at the same time releases heat, which is transferred to the water in the tank, thus realizing hot water production.But the refrigerant's mission does not end there. It is about to arrive at the next battlefield

    4.Expansion valve The expansion valve controls the refrigerant flow in the heating system by changing the throttling section or throttling length.The expansion valve throttles the liquid refrigerant of medium temperature and high pressure through it, and turns it into wet steam of low temperature and low pressure. Then the refrigerant will enter the evaporator again, so as to enter the next thermal cycle, so as to ensure the supply of hot water.
