When the ambient temperature drops to below zero degree in winter, the normal air source heat pump can not run stably caused by small gas absorption, small system gas flow, the system low evaporated temperature and unstable superheat degree, etc . So that the air source heat pump’s heating output is low , the system runs unstably , even worse to cause the compressor damaged. Normal air source heat pump can not meet the heating requirement in the cold area in winter.

HISEER mono-bloc injection air water heat pump can be used at -25℃ low temperature. The heat pump delivers higher capacity at low evaporating temperature thereby better responding to heating requirement thanks to EVI compressor and electronic expansion valve plus Carel electronic pressure transmitter.
