Goldsun Air source heat pump (EVI series, -20 degree)

Air source heat pump for cooling and heating 1. -25DC low temp use 2. R410a, high COP to 4.8 3. EVI design 4. CE approved

Goldsun EVI split air source heat pump  (house heating heater ) for house heating and cooling.

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

EVI split design, the compressor and water part system is split design for cold area to install inside the house. Thus, the system can provide stable running in even -20 DC environment, avoid any antifreeze problem

 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 degree, EVI technology importantly increase refrigerant flow of the main loop and outside evaporation enthalpy 

difference, brings 7% to 34% additional heating.
