摘　　要：对长沙某互动战船馆的空调系统进行了逐时负荷计算,负荷结果显示室内需全年供冷除湿,过渡季和冬季非常适合利用室外“免费”的新风冷源。根据典型年室外气象数据,经过热湿平衡计算分析得出过渡季通风除湿的切换时间范围,在不保证率α为3%的条件下,通风运行时间为888 h,占总运行时间的20%。由冬季空气处理焓湿计算分析发现,冬季通过加大新风比运行,利用室外的干冷空气可以达到除湿效果,且其空气处理的焓差仅为带热回收冷冻除湿的65%。根据制冷/热量、主机COP或SCOP值、锅炉效率、输配设备电量估算值和运行时间,计算得出空调通风耦合除湿与带热回收冷冻除湿的全年能耗的理论估算值,对比发现前者较后者节能27%。Hourly load calculation of an interactive battleship hall in Changsha was carried out. The load results show that indoor cooling and dehumidification are necessary throughout the year. Transition season and winter are very suitable for the use of outdoor “free” fresh air cooling sources. According to the outdoor meteorological data of typical years, the switching time range of ventilation and dehumidification in the transition season was obtained through the calculation and analysis of heat and moisture balance. Under the condition of unguaranteed rate α of 3%, the ventilation operation time was 888 h, accounting for 20% of the total operation time. According to the calculation and analysis of enthalpy and humidity of air treatment in winter, it was found that the desiccant effect could be achieved by increasing the fresh air ratio in winter, and the enthalpy difference of air treatment was only 65% of the heat recovery refrigeration dehumidification. According to the estimated values of refrigeration/heat, COP or SCOP value of main engine, boiler efficiency, power consumption of transmission and distribution equipment and operation time, the theoretical estimated values of annual energy consumption of air conditioning and ventilation coupled dehumidification and heat recovery refrigeration dehumidification were calculated. The comparison showed that the former was 27% more energy-saving than the latter.
