air source heat pump (-25 degree)
When the a mbient temperature drops to below zero degree in winter, the normal air source heat pump can not run stably due to the system low evaporation temperature, small gas absorption, small system gas flow and unstable, even cause trouble like compressor liquid hammer etc.Normal air source heat pump can not meet the heating equirement in the cold area in winter.
Goldsun uses the most advanced low- temperature Enhanced Vapour Injection compressor technology. EVI heat pump delivers higher heating capacity at low evaporation temperature thereby better responding to heating equirement than normal air source heat pump, It also results in less supplementary heating to cover the full heating demand on the coldest days. It has been further optimized to enable heat pumps to efficiently produce water temperature up to 60 DC during cold winter time.
EVI compressor has an additional port to inject vapour in the compression process. This improves the performance of the system by increasing the heating capacity for a given
compressor displacement. Additional benefits are the eduction of the discharge temperature and the extension of the operating envelope for the production of high temperature water.
Advantages:
1. EVI air to water heat pump is specially designed for house heating in cold area. The ambient temperature range is -25DC to 43DC. It can use safely in -20DC ambient.
2. Normal heat pump is difficult to heat below -5 DC. EVI technology importantly increase refrigerant flow of the main loop and outside evaporation enthalpy difference, brings 7% to 34% additional heating.
3. A strong low-temperature heating capacity.
4. EVI heat pump significantly improves the problem of insufficient flow of refrigerant in low-temperature environment by the secondary compressor suction, making it will be useful even if the outdoor temperature is as low as -20DC and without abvious thermal decay problem.
