1. Frosting and Defrosting of Air-Coils
Abstract : Experience indicates that air-source heat pumps have more operating problems than ground-source heat pumps. One major factor pertains to the effects of frosting and the subsequent need for defrosting. This thesis reviews previous research and practical experience and presents novel experimental facilities to investigate the process of frosting. READ MORE
