Abstract
The calculations of power consumption and energy efficiency for household air conditioners with inverter technology using bin method in the Vietnamese climatic conditions were shown in the paper. The data of 53 of the air-cooled air conditioners in the Vietnamese market with rated cooling capacity in the range of 9000 BTU/h to 24000 BTU/h were used in this study. Based on the National Standard on the air-cooled air conditioners and heat pumps (i.e., TCVN 10273-1:2013) and National Regulation on climate data for construction (i.e. QCVN 02:2009), the cooling seasonal power consumption and energy efficiency have been calculated for 10 cities/provinces, representatively of different climatic zones in Vietnam. The results show that there are quite large deviations between energy efficiency (CSPF) and annual power consumption (CCSE) from the national standard TCVN 10273-1:2013, national regulation QCVN 02:2009 and published data of manufactures. The impact of the Vietnamese climatic zones on the power consumption was investigated in the study, also. The paper suggests the necessary of upgrading the national standard and regulation for inverter air conditioners to evaluate exactly their energy efficiency in the Vietnamese climatic conditions.
