Abstract

An air source heat pump system (ASHPS) was setup, which provided space heating and cooling, as well as hot water for an office building in Tianjin. Its operating performance in winter was evaluated based on test data including water inlet and outlet temperatures, ambient and room temperatures, relative humidity and energy combustion under different operation modes. Then a comparative discussion is given on the effect of climate conditions and heating load ratio on the operation behavior, and an analysis of heating capacity variation caused by evaporator frosting is carried out as well. Finally, the defrosting parameters and the technical feasibility are studied for a constant heating demand.
