On the 16th of this month, 11 departments including the Beijing Municipal Development and Reform Commission jointly issued the Beijing Implementation Plan for Further Strengthening Energy Conservation (2023), which proposed to promote the use of primary energy-efficiency air-source heat pumps for heating to promote building electrification. So what is air source heat pump? What is the working principle of air source heat pump?

Literally, air-source heat pump is a kind of pump. The pump can convert the position energy that can not be directly used into the high level heat energy that can be used, so as to achieve the purpose of saving part of the high level energy.

The working principle of the Kcalin air source heat pump is that the unit drives the compressor by consuming a small amount of electric energy, absorbs the low temperature heat in the air, and then carries out heat exchange through the evaporator to apply the high level heat energy obtained. At present, the main application fields include air source heat pump heating, air source heat pump water heater, agricultural drying and other fields.

As a renewable natural resource, air energy is used by heat pumps and supplemented by clean energy - electric energy, which does not cause environmental pollution during operation. It is a green environmental protection equipment that vigorously promotes and develops renewable energy in China. At present, most of the "coal to electricity" projects in northern China use air source heat pump units for heating.

The STS series Kcalin air-source heat pump units, using the "STS" continuous heating technology independently developed by Kcalin, overcome the technical problem of high heat consumption of "reverse defrosting" of air-source heat pumps, and realize the industry dream of efficient and stable continuous heating of heat pump units. Compared with the traditional reverse defrosting technology, the heat consumption of defrosting can be saved by more than 25%.

Kcalin air source heat pump is not only safe and environmentally friendly, but also has outstanding energy-saving effect; An average of 1KW of electricity can convert 4KW of heat energy, which is four times as much as electric heating and twice as much as solar energy. The operating temperature range of the unit is - 25 ℃ - 43 ℃, and multiple protection mechanisms are set, which can be widely used in industrial and commercial refrigeration and heating projects in most areas of North China and the Yangtze River and Yellow River basin.
