An ASHP unit is chosen to compute EER and performance under frosting as the unit operates under different air temperature, air humidity and different hot water.
A two-stage compression variable frequency air source heat pump (TV-ASHP) has been developed combining variable frequency technology with two-stage compression cycle.
