Abstract

While nominal COPs which are determined under a steady static condition cannot represent the actual system efficiency of heat pumps, seasonal energy efficiency ratings (SEER) are used for the more realistic performance assessment. SEERs are calculated by taking account of building energy partial load patterns which are determined by outdoor temperature bin and simplied heating/cooling load calculation. Although SEERs could be used for the assessment of the system performance, it is questionable that the nature of the simplified calculation provides accepvy accuracy of the results taking account of building configuration(e.g. thermal capacity, window ratio etc), regional climate conditions etc). The purpose of this study is to test the applicability of SEERs of heat pump systems integrated within a building. The KS C 9306 method for calculating SEERs was investigated and used for the comparison analysis with the detailed simulation tool Energyplus in terms of system efficiency rates according to the partial load profiles.
