Low temp EVI air soruce heat pump water heater
Product features::
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 obvious thermal decay problem.
