Air to Water Heat Pump for Space and DHW Heating and Space Cooling - EVI Technology for Canadian Climate - Model MAFP

The Air to Water Pump is a revolution in heat pump technology that remains unsurpassed in terms of cost and performance. 

Designed with a mission to make it the most efficient cold climate heat pump on the market at a price point of ½ of a traditional geothermal heat pump.

This was done without any sacrifices to quality. Industry leading parts were mandated in the design of this unit.

Remarks:

1. ①Cooling: DB 35℃/24℃, inlet water temp. 12℃, outlet water temp. 7℃.
2. ②Heating: DB 7℃/WB 6℃, outlet water temp.: 55℃.
3. ③Heating: DB 7℃/WB 6℃, outlet water temp.: 45℃.
4. Working ambient temp. range: -25℃～43℃.

EVI stands for “Enhanced Vapor Injection” and is a technology used on our cold climate heat pumps to achieve higher performance at lower temperatures. An EVI heat pump uses a 3rd smaller internal plate heat exchanger called an “Economizer” within the refrigeration cycle. By utilizing a bypass valve some of the hot refrigerant vapor on the condenser is bypassed to a HX which combines with the colder gas on the Evaporator expansion side.

The heat energy is transferred raising the gas temperature even further which is then injected at mid-range pressure into the head of the scroll compressor through a separate vapor injection port. Using EVI heat pump technology, we are able to overcome the limitation of maximum flow temperature that other cold climate heat exchangers encounter.

EVI Heat Pump technology allows more heat to be delivered resulting in a better COP at much lower temperatures. The EVI technology increase performance efficiency by 27-30%.
