Airsour ultra-low temperature air source heat pump hot water series unit adopts the international leading level of air injection enthalpy technology, which ensures the stable and reliable operation of the unit even in low and extremely cold ambient temperature. The unit adopts intelligent defrosting technology, which shortens the defrosting time greatly and the energy-saving effect does not decay. All components of the unit are made of international first-class brands, which are safe and reliable and have a service life of more than 15 years.
The household hot water air source heat pumps have the advantages of high efficiency, low noise, reasonable structure, easy operation, safe operation, easy installation and maintenance, etc. They are widely used in hotels, hotels, schools, swimming pools, factories, and other public places, and can meet the hot water needs of different industries. The heat pump works by extracting heat from the outside air and transferring it to water, which can then be used for space heating, domestic hot water and other applications. The system uses electricity to drive the heat pump compressor, but it is more energy efficient than traditional heating systems because it does not rely exclusively on fossil fuels. Hot water air source heat pumps are a renewable energy technology that can help reduce carbon emissions and lower energy bills.

Technology Principle
4Q (energy obtained) = 1Q (electrical energy) + 3Q (environmental heat)
According to the principle of inverse Carnot cycle, the unit takes a small amount of electric energy as the driving force and refrigerant as the carrier to continuously absorb the low-grade heat energy in the air that is difficult to use and convert it into usable high-grade heat energy to realize the transfer of low-temperature heat energy to high-temperature heat energy: then transfer the high-grade heat energy to water to make domestic hot water (55℃~60℃) and deliver it to the water end through the hot water supply pipeline to meet domestic hot water and heating The demand for domestic hot water and heating is met through the hot water supply pipeline to the water end.
