Low Ambient Temp EVI Air Source Heat Pump
Features and Advantages of the Low Ambient Temp EVI Air Source Heat Pump
1. Our EVI air source heat pump is specially designed for house heating in cold area. The ambient temperature range is -25℃ to 43℃. It can be used safely in -20℃ ambient.
2. In comparison with normal heat pump which presents difficulty in heating below -5℃, our EVI technology importantly increases refrigerant flow of the main loop and outside evaporation enthalpy difference brings 7% to 34% additional heating.
3. It features a strong low-temperature heating capacity.
4. EVI air source heat pump significantly improves the problem of insufficient flow of refrigerant in low-temperature environment by the secondary compressor suction, making it useful even if the outdoor temperature is as low as -20℃ and without obvious thermal decay problem.
5. Although EVI heat pump costs more than normal heat pump, but it brings you more benefits on the base of total cost as it eliminates the initial investment for central heating device and the operating cost is extremely low.
6. The heating capacity is 11.16-36.3.1kW, for hot water outlet is 30-65℃, making it suitable for central heating and sanitary hot water.
7. The Emerson Expansion Valve keeps the system's pressure in balance with America Copeland Compressor.
8. Our heat pump features compact design, easier installation and takes up less space.
9. It adopts thermal insulation for all pipes with low heat loss.
10. Our air source heat pump has high efficiency reverse circuit design with auto defrosting function.
11. Its drainage hole can discharge out condensed water fluently.
12. The fans operate in quiet mode offering low noise.
13. The wire controller of our air source heat pump is installed indoor, making it convenient for users.
14. R22/ R417A /R407C Refrigerants for heat pump are all available.
15. Fashionable design with fan discharging in horizontal and vertical style is also offered,
16. Powder coated or 304# Stainless steel cabinet are applied, it is anti corrosion and durable to use for more than 10 years.
17. The whole units are warranted for a period of one year.

When the ambient 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 and small system gas flow unstably, even causing trouble like compressor liquid hammered. Thus, our low ambient temp EVI air source heat pump in contrast to the normal air source heat pump can be the perfect solution to meet the heating equipment in the cold area in winter. Adopting the most advanced low- temperature enhances vapors Injection Compressor Technology. This heat pump delivers higher heating capacity at low evaporation temperature thereby better responding to heating requirements 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 65℃ during cold winter time.
We are a manufacturer and supplier specialized in low ambient temp EVI air source heat pump in China. We also offer commercial air source heat pump, household heat pump water heater, solar water heater, and many others.
