EVI Air Source Heat Pump Water Heater:

• Advantages:

1. EVI technology overpasses other enthalpy VRF systems, because it can also provide better heating performance even in low ambient temperature, without the auxiliary heating system such as boiler or combustion heater.
2. The raise of the outside evaporation enthalpy difference improves the heating capacity of the unit.
3. Normal heat pump is difficult to heating below -5^oC. EVI technology importantly increases refrigerant flow of the main loop and the outside evaporation enthalpy difference, brings 7%~34% additional heating.
4. Conducive to terminals: a.More efficient: The COP of EVI technology is very remarkable even at low ambient temperature.b.Low operating cost.c.No auxiliary heating systems: EVI technology can provide a long-term solution to families and buildings to reduce operating cost.
5. Low equipment cost: Normal heat pump has been accepted by the market, and its price is competitive. 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. Easy installation: EVI heat pump is suitable for both heating and cooling, and eliminates the need for the boiler. It do not need large installation space as it can be installed outdoor, on the roof and balcony. And its inside safety device ensures a good reliability.
7. A strong low-temperature heating capacity: 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 -15^oC and without obvious thermal decay problem.

• Scope of application: villa, hotel, sauna center, dormitory, restaurant, etc. Especifically designed for low-temperature conditions: Suitable temperature range is -15^oC ~43^oC
