What is the working principle of air source heat pump?
Air-source heat pump is an energy-saving device which uses high-level energy to make heat flow from low-level heat source air to high-level heat source. This is a kind of heat pump. As the name implies, a heat pump, like a pump, can convert low-level heat energy (such as heat contained in air, soil and water) that cannot be directly utilized into high-level heat energy that can be utilized, thus achieving the purpose of saving some high-level energy sources (such as coal, gas, oil and electric energy).

Working principle:

The heat pump uses the inverse Carnot principle to absorb a lot of low-temperature heat energy in the air with very little electric energy, which is converted into high-temperature heat energy through the compression of the compressor and sent to the water tank to heat hot water, so it has the advantages of low energy consumption, high efficiency, high speed, good safety, strong environmental protection and continuous supply of hot water.

The working principle diagram of air source heat pump is hot water system, which has incomparable advantages. The heat pump hot water unit follows the law of conservation of energy and the second law of thermodynamics. Using the principle of heat pump, only a small part of mechanical work (electric energy) is needed to transfer heat in low temperature environment (atmosphere or groundwater, etc.). ) add it to a water heater in a high temperature environment to make high temperature hot water.

Extended data:

Air source heat pump has the following characteristics? :

(1) The air source heat pump system integrates cold and heat sources, and there is no need to set up a special refrigeration room and boiler room. The unit can be placed on the roof or ground at will, without occupying the effective use area of the building, and the construction and installation are very simple.

(2) The air source heat pump system has no cooling water system, so it does not consume cooling water, and the cooling water system does not consume electricity. In addition, there are many reports of Legionella infection caused by cooling water pollution. From the point of view of safety and hygiene, air source heat pump also has obvious advantages.

(3) The air source heat pump system needs no boiler, corresponding boiler fuel supply system, dust removal system and flue gas exhaust system, which is safe and reliable, and has no pollution to the environment.

(4) The air source heat pump cold (hot) water unit adopts modular design, and there is no need to set up a standby unit. In the process of operation, the computer automatically controls and adjusts the running state of the unit to adapt the output power to the working environment.

(5) The performance of air source heat pump will change with the change of outdoor climate.

(6) In the area with low outdoor temperature in northern China, auxiliary heaters are needed because of insufficient heat pump heating in winter.
