Goldsun air  to water Heat pump 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. Compressor and water system split design, can install inside the house in cold area to provide stable running and avoid any anfifreeze problem.

2. 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.

3. 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.
