Source EVI Heat Pumps For Cold Climates

EVI stands for Enhanced Vapor Injection, which is a technology utilized in our low-temperature heat pumps to deliver higher performance in cold climates. EVI allows a 20% increase in refrigerant flow into the evaporator at a lower entry temperature. It incorporates a 3rd smaller internal plate heat exchanger referred to as an "Economizer" in the refrigeration cycle. Some of the refrigerant vapor on the condenser combines with the cooler gas on the expansion side of the evaporator through a bypass valve. This combination leads to the transfer of heat energy, which increases the gas temperature further and is then injected into the head of the scroll compressor through a separate vapor injection port at mid-range pressure. With EVI heat pump technology, the maximum flow temperature limitation of other cold climate heat exchangers is overcome, and more heat is delivered, resulting in a better COP at much lower temperatures. The performance efficiency is increased by 20-30%.

guangteng are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

Monobloc EVI DC Inverter Heat Pump

These air source heat pumps use environmentally friendly refrigerant R32. Thanks to its full DC inverter technology, it can operate in temperatures as low as -7 degrees Celsius with noise levels as low as 52 decibels. In addition, each device is equipped with a Wi-Fi remote control function.
It is worth mentioning that the domestic air source heat pump produced by PowerWorld has precise temperature control and higher comfort. The household air source heat pump system has a more significant temperature working range. It can automatically change the flow rate according to the ambient temperature and water temperature data to ensure the stable operation of the unit.
PowerWorld household air source heat pumps are different from traditional solar heat pumps. They are not affected by wind, light, precipitation, snow, and other natural environmental factors. They can switch different functions in different seasons of the year, heating in winter, cooling in summer, and all year round. Provide domestic hot water.
