Analysis of Air Source Heat-Pump System Assisted by Solar Energy

Article Preview

Abstract:

The steady state distributed parameter model of heat exchangers in a heat-pump system was established in this paper. The calculating results of refrigerant quantities in the heat-exchangers show that refrigerant charge quantity in heating operating condition is less than that in refrigeration operating condition. Based on the differences of refrigerant mass flux between refrigeration and heating conditions, the exhaust bypass method to improve the operation efficiency of the heat-pump system was presented. And in order to prevent frosting on the surface of outdoor heat exchanger of the air source heat-pump, the solar energy assisted strategy was also applied in the heat-pump system.
