Abstract：Taking a three-star hotel in Jinan City as the research object,the building model of the hotel is established,the dynamic load of the air conditioning system is calculated,the characteristics of the fresh air load of the building is analyzed,and the energy waste of the fresh air system under different occupancy rates is discussed.The results show that the proportion of fresh air load in total heat load is 69.37%and that of sensible heat load is 68.81%due to the influence of temperature difference between indoor and outdoor.The decrease of the occupancy rate leads to a significant increase in the waste rate of fresh air energy consumption,with the average waste rate reaching 31.99%.Under winter operating conditions,the maximum energy waste rate of the fresh air system can reach 56.46%.
