STUDY ON EXPANSION OF APPLICABLE AREA FOR AIR CONDITIONERS (AC) FOR HOUSES THAT MEET ZEH EXTERIOR SKIN PERFORMANCE AND SOLAR RADIATION SHIELDING STANDARDS

ZEHs, which take into account the insulation performance of the external skin and the reduction of solar heat gain during the cooling season, are becoming increasingly popular. In this paper, the relationship between the rated capacity of AC and the applicable floor area in ZEH was investigated based on the heating and cooling load of the LDK of ZEH and the heating and cooling capacity of AC. The average power consumption of ACs in LDKs of ZEHs in actual dwellings was also obtained from HEMS data to estimate the operating conditions.
