摘　　要：以佛山市某酒店为例,计算其空调冷热负荷及生活热水负荷。基于负荷特点,选择传统多联机+燃气锅炉与三管制热回收多联机2种冷热源方案进行经济性对比。通过月累积负荷、月平均温度结合机组变工况能效比进行运行费用估算。结果表明,三管制热回收多联机在酒店建筑的应用中具有较好的节能性和经济性。Taking a hotel in Foshan city as an example,its air-conditioning cold and heat load and living hot water load are calculated.Based on its load characteristics,two cold and heat source schemes of traditional multi-connected air-conditioning(heat pump)unit+gas boiler and three-pipe heat recovery multi-connected air-conditioning(heat pump)unit are selected for economic comparison.The monthly cumulative load and monthly average temperature combined with the energy efficiency ratio of the unit under variable operating conditions are used to calculate the operating cost.The results show that the application of three-pipe heat recovery multi-connected air-conditioning(heat pump)unit in hotel building has good energy-saving and economy.
