Abstract
The air-conditioning industry consumes about 20 per cent of the total electricity consumed by residential buildings in the country;one of the ways in which the air-conditioning industry has addressed the growing demand for heating in the winter is to add electrically assisted heaters to indoor units.However,the efficiency of converting electrical energy into heat is much lower than the energy efficiency of air conditioners in heating mode.Prolonged use of electrically assisted heating can have an impact on air conditioning energy consumption and energy efficiency.In order to study the specific impact of energy consumption and energy efficiency of air conditioners using electric auxiliary heating in typical residential buildings,a certain model of 2HP air conditioner model was selected for multi-operating condition measurement,and the predicted curve of air conditioner performance for the whole year was obtained through data analysis,and a model was established for a certain residential house type,and the predicted power consumption of the living room in the whole year of the use of electric auxiliary heating in the 2HP air conditioner and the unused electric auxiliary heating was calculated through the simulation of the outdoor meteorological conditions in Nanjing,as well as the impact on the energy efficiency of the air conditioners.The results show that a typical residential building in Nanjing consumes an additional 44 kW·h of electricity in the living room with 2HP air-conditioning with electric auxiliary heat,which reduces the seasonal energy efficiency(HSPF)by 12.87％during the heating season,and reduces the annual energy efficiency(APF)by 5.61％.关键词
