Study on Performance of Air Source Heat Pump Water Heater


Article Preview

This paper introduce the working principle and classification of air source heat pump water heater. Thermodynamic calculation of the air source heat pump water heater is carried out, such as air source heat pump water heating coefficient, energy saving effect, and the cooling effect of the surrounding environment, and primary energy utilization of heating conditions of several forms. The primary energy utilization rate of air source heat pump water heater is the highest, and showing a good energy-saving.
