In this study, an annual heating performance of a seawater-source heat pump, assumed installed in Gangneung city near the East Sea in Korea, was simulated. An annual heating load for a typical Korean-style apartment house, which has an effective area of about 85 ㎡, was modeled by using TRNSYS program. The seawater temperature was calculated from the regression equation based on the measurement. A heat pump performance at full-load was calculated from the regression equation, which involves refrigerant’s evaporating and condensing temperatures, based on a commercial compressor performance map. A part-load performance was also considered. Simulation results show that an annual heating coefficient of performance (COP<SUB>H</SUB>) of a seawater-source heat pump is approximately 3.3 and that it is necessary to improve part-load performance to increase an annual performance of the heat pump.
