EVI Technology 


Air-source heat pumps have been used for many years in nearly all parts of the world, but until recently they have not been used in areas that experienced extended periods of subfreezing temperatures. However, in recent years, EVI air-source heat pump technology has advanced so that it now offers a legitimate space heating alternative in colder regions.

Advantages of Deakon Commercial Air to Water Heat Pump 


Normal operation at -20~40 ℃

Designed for all season heating operation in the north countries, it operates normally under 0℃ environment.

Heat increased by 30%

The application of  EVI (enhanced vapor injection) technology can improve the heating capacity at low temperature by about 30% compared with conventional heat pump.

Higher energy efficiency ratio

The energy efficiency ratio at low temperature is higher, and the energy efficiency ratio of the unit at - 20 ℃ is as high as 2.0

Hydrophilic corrugated fin evaporator

The evaporator adopts hydrophilic corrugated fins, which has larger heat absorption area, higher efficiency, and faster and more thorough defrosting.


CORE COMPONENTS 



EVI Compressor 


The Copeland ZW series scroll EVI compressor is specialized for heat pump applications, It adopt  flexible vortex technology which can better adapt to long-term stable operation in harsh environment, and multiple safety protection are set to effectively ensure the service life of the product.



Fan


High efficiency metal fan is adopted to greatly provide large air circulation and improve heating efficiency. The metal fan blade has a longer service life.



Four Way Valve and Electrical Expansion Valve 

Switch the heating/cooling mode and adjust refrigerant flow.  Deakon C1 series heat pump uses high quality valve to ensure the reliability.


High and Low Pressure Protection Valve


High and Low Pressure Protection Valve

If these two small parts are not added, the system still can be operated, but over a long period of operation, it will cause uneven pressure on all parts and local dry burning. Where the pressure is too high, the high-pressure pipeline will burst.  The whole system is in a state of uncontrolled and unmanaged , which eventually leads to excessive pressure and excessive aging of components, which affects the performance of the whole machine and enters the scrap period in advance.
