1.Application of Air Source Heat PumpEVI low temperature air source
heat pumps absorb low-grade heat energy from the air to provide
domestic/commercial heating or hot water. 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 - 25ºC and supply
heating in cold areas. In some areas, the lowest temperature
in winter can reach minus 25ºC. Under such a low temperature
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 source heat pumps, resulting in inability
to start or unstable heating. It is recommended to use EVI air
source 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 low temperature
environment. Now they are widely used in cold climate for heating
and hot water supply.Eurostars EVI Air source heat pumps can supply
domestic/commercial room heating and cooling. Wide Range of
Applications: air to water heat pumps could meet the space
heating and cooling requirements of different places, such
as villas, families, schools, factories, hotels, hospitals,
sauna centers, greenhouses, flower gardens, farms, etc.2.Eurostars
