Introduction of R290 Air Source Heat Pump

R290 air source heat pump is efficient for house heating, cooling and domestic hot water.

R290 air source heat pump, with R290 refrigerant can achieve a high water temperature up to 75℃，heat pump installation is convenient and the original gas boiler system like radiators and water pipes can be kept, achieving integrated multi-heat source and energy saving.

The result shows that the theoretical cycle performance of R290 is equivalent to that of R22.The COP of nominal cooling could be up to the third level of energy efficiency stated in GB19577-2015.The COP of nominal heating could be up to 3.27.The working pressure and discharge temperature of the compressor for R290 system are lower than those of R22 system.The protection value of high pressure can be reduced to 2.6 MPa,and the protection value of high discharge temperature can be reduced to 95-105 ℃. Using the heat exchange tube with smaller diameter can greatly reduce the charge of R290.

With less CO2 emission, let’s take care of our green planet together.
