Different ambient temperatures will affect the service effect and the service life of the heat pump unit. Under the low ambient temperature in the north, it is necessary to use ultra-low temperature heat pump specially for low ambient temperature to ensure the normal start and operation of the heat pumps.. Solarshine ultra-low temperature air source heat pump adopts a special heat pump compressor, which can also operate stably, heat efficiently and prolong the service life of the unit under the condition of ultra-low temperature environment to -25℃.

Why can air source heat pump work stably at - 25 ℃?
Many people's misunderstanding of air source heat pump mainly focuses on whether it can operate stably at low ambient temperature，mainly because they still stay in their previous understanding of ordinary heat pumps and lack sufficient understanding of low-temperature heat pumps.
The core component that causes the performance difference between low-temperature heat pump and ordinary heat pump is compressor. The reason why the low-temperature heat pump can operate normally under lower ambient temperature is to solve several problems encountered by the conventional heat pump - insufficient heating capacity, low cop and unstable operation caused by low evaporation temperature, low suction flow, large compression ratio and high exhaust temperature.
The first is the internal structure design. The scroll profile of the low-temperature heat pump compressor is designed larger, which means that under the condition of lower evaporation temperature, the low-temperature heat pump can obtain higher working efficiency and lower evaporation temperature working range to adapt to the working environment with large temperature difference.
