About EVI Cold Climate Heat Pumps
EVI air source low temperature heat pumps absorb low-grade heat energy from the air to provide domestic/commercial hot water and space heating. They can also function as cooling devices in summer. These cold climate heat pumps are developed using the Enhanced Vapor Injection (EVI) compressor technology and high-efficiency eco-friendly refrigerant, which ensures that the units can work normally at as low as -25℃ and supply heating in cold areas.
In some areas, the lowest temperature in winter can reach minus 25℃. Under such a low temp environment, it is difficult for ordinary air source heat pumps to maintain a good heating capacity. Low ambient temperature will lead to severe frosting of air to water heat pumps, resulting in inability to start or unstable heating. It is recommended to use EVI air to water heat pumps in cold weather. They apply special low temperature technology, special low temperature compressors and low temperature refrigerants to ensure normal start-up, stable operation and efficient heat supply under a cold environment. Now they are widely used in cold areas for heating and hot water supply.
As one of the cold climate heat pump manufacturers, SPRSUN provides the best split type EVI low temperature DC inverter air source heat pumps for sale, which consist of an indoor unit that blows air over evaporator coils and an outdoor unit that powers the system. These split models can better avoid freezing problems, with automatic anti-freezing protection by detecting system water temperature. Compared with regular EVI low temp heat pumps, these split system DC inverter heat pumps with max. COP 5.60 can work more efficiently in cold areas.
