Low temp air water heat pump 1. --25D Low temp use, EVI 2. cooling and heating designe 3. R410A, COP to 4.5 4. CE approve

Goldsun uses the most advanced low Temp Enhanced Vapour Injection compressor technology and  have  successfully produced  the EVI low  temperature  heat  pump. 

Compare to the common series heat pump, you will see below advantages: 

1. 43°C ~-25°C wide range use.   EVI air to water heat pump is specially designed for house heating in cold area. The ambient temperature range is -25°C to 43°C. It can use safely in -20°C ambient.

2. Strong low-temperature heating capacity              

Normal heat pump is difficult to heat below zero 5 °C ,  EVI technology importantly increase refrigerant flow of the main loop and outside evaporation enthalpy difference, brings 7% to 34% additional heating.
