Summary

The defrosting of a heat-pump evaporator with warm air has been investigated experimentally under controlled conditions in an air-conditioned wind tunnel. The work was initiated to explore the possibility of defrosting an evaporator under conditions where a heat pump continues to perform heating duty. The rate of melting was determined as a function of air temperature, relative humidity and velocity. Evaporator weight is mesured to appreciate frosting state. The removal from the evaporator surfaces of water produced by defrosting depends on air velocity.
