This is EVI  inverter design for 60^oC higher water temperature, especially for the extremely cold area, like -25^oC ambient temperature; Its core philosophy is to solve the house heating during the cold climate in Winter and Spring and make room cooling in hot Summer and Autumn. This kind of design can do not only heating and cooling but also can provide sanitary hot water all over the year because the second circle heating can use 60^oC hot water to heat the 10~15 ^oC tap water to 55 ~60 ^oC sanitary water. So it is realized to offer heating,cooling and sanitary hot water with only one heat pump.

And because the DC inverter technology,the frequency will change as the ambient temperature and water temperature, heat pump will work as actual heat/cool demand,more energy-saving.

The heat pump performance has been improved greatly as new designed EVI inverter  compressor from the United States Emerson Ltd and with MACON specially designed economizer and high efficiency heat transfer module.With six months of performance testing and validation in the different conditions of Multifunctions Lab.,the EVI inverter Series Heat Pump has reached the COP=4.2  for floor heating mode (EN14511-2007) and it is available for 60 ^oC hot water output and safely working in -25 ^oC ambient temperature.

1. Higher Water Temperature Output up to 60^oC
2. Safely Working Temperature Down to: -25^oC

3. High Efficiency COP up to 4.2 (EN14511-2007)

4. Three in One : Heating, Cooling and Sanitary Hot Water
