| Abstract |
The purpose of this study is to present the applicability of the in-situ measurement method of an air source heat pump as part of the energy
diagnosis of existing buildings. For this purpose, the air enthalpy difference method for outdoor equipment in an air-source heat pump system
was focused on. Two pilot projects were attempted to confirm the accuracy of the air enthalpy difference method in the cooling performance
diagnosis of the air source heat pump operated in the field. The field test results confirmed that the compressor set energy conservation
(CSEC) method required more expertise in the cooling performance measurement of an air source heat pump and was suitable for short-term
investigation within a day. The cooling performance of the air-source heat pump by the air enthalpy difference method in the outdoor unit
had a mean error of 10% compared to the CSEC method. Nevertheless, it showed that this method was more suitable for the simplified
in-situ measurement method because it had the advantages of ease of measurement and the simple analysis processing method required for
in-situ energy performance diagnosis. |
