Problems With Air Source Heat Pump Applications
Apr 20, 2022
In the cold regions of my country, the temperature in winter is lower and the climate is dry. The calculated outdoor temperature for heating is basically -5 to -15 °C, and the average outdoor relative humidity in the coldest month is basically between 45% and 65%. In these areas, air source heat pumps are used, and the frosting phenomenon is not too serious. Therefore, the frost problem is not the biggest obstacle to the use of air source heat pumps in winter in these areas. However, there are the following problems that restrict the application of air source heat pumps in cold regions.
(1) When the required heat is relatively large, the heating capacity of the air source heat pump is insufficient.
(2) The reliability of air source heat pumps in cold regions is poor.
(3) In a low temperature environment, the energy efficiency ratio (EER) of the air source heat pump will drop rapidly.
