H'Stars standard ultra-low temperature air source heat pump unit operates stably in the environment of -25℃ ~ 43℃, using air as a heat source, no pollutants are discharged, and 55 °C hot water is prepared to meet the demand of hot water between 35-55 °C. Heating function, suitable for direct air supply or floor radiation heating.

Hot water chiller(cold recovery) is using the air as low heat source to produce the heat water. Energy saving, high efficiency and environmental protection, the waste cold discharged in the heating process is recovered through the cold recovery device, to improve the comprehensive energy efficiency and realize zero cost refrigeration

The air source heat pump has five functions: refrigeration, heating and domestic hot water classification. It can realize summer cooling and winter heating. It provides domestic hot water for the whole year, so that one machine can be used, saving floor space and reducing Initial investment, saving more than 40% of the cost of use.
