High Efficiency Commercial Industrial Use Air to Water Building Heating and Cooling Heat Pump

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 Air Source Heat Pump Features:1) EVI compressor special designed for high COP (Coefficient of Performance): 4.0 even in bad weather condition or area.  2) Base frame and external panels made of galvanized powder coated steel                         3) Water exchanger equipped with high efficiency tube in shell heat exchanger                         4) Reliable compressor with R407C/R410A refrigerant                     5) Stable water flow switch & backflow proof.                        6) Fully sealed control box with water proof level IPX4                      7) Intelligent microprocessor control systems                       8) Air exchanger (fin-coil) with hydrophilic coating                      9) Thermostatic heating element for evaporator, anti-frosting10)Every capillary tube of SANHUA/DANFOSS/EMERSON expansion valve full-covered by silicon/soft pipe refucing buffer friction, subtle vibration from compressor/fan, keeping strong as 15-20 years working life, even longer.                          11)No need of auxiliary electrical heating and works well even at -25 ºC~30 ºC.   12) Lowest noise that fan motor & Copeland high efficient compressor, thermostability PE material with bond for soundproof & heat preservation.   3.
