Abstract：Taking the passive ultra-low energy consumption building of a certain university as the research object,the Hongye annual load calculation and energy consumption analysis software HY-EP5.0 is adopted to calculate the annual hourly cooling and heating load of the building and the comprehensive energy consumption of the air conditioning system with three different cooling and heating sources,as well as conduct economic analysis.The results show that in passive ultra-low energy consumption buildings,in terms of air conditioning operation energy consumption,the ground source heat pump system can achieve energy-saving rates of 32.4%and 37.3%respectively compared with the chiller+municipal heat source system and the air source heat pump system,and the cost savings rates can reach 5.3%and 12.1%respectively.
