【摘要】 以西安地区某办公楼为代表,通过对西安地区气象参数的统计,对中湿度地区蒸发冷却与机械制冷相结合的集中式空调系统、蒸发冷却与风机盘管相结合的半集中式空调系统,分别与传统的集中式和半集中式空调系统进行了对比分析。结果表明,采用蒸发冷却与传统空调方式的结合,可以大大减少冷水机组装机冷量和运行时间,从而节约了运行成本,提高了系统的能效比,为中湿度地区蒸发冷却工程应用提供了依据。 【Abstract】 Take an office building in xian for example.With the statistical result of the outdoor meteorological parameter,we compared the evaporative cooling assisting to mechanical refrigeration with traditional central air conditioning system and compared evaporative cooling plus fan coil with semi-central air conditioning system.Form the result,we can draw that it can reduce the cooling capacity of chillers and run-time significantly in the combined air conditioning modes of evaporative cooling.Therefor we saved the running costs and improved the energy efficiency of the system,as well as provided a basis for engineering applications of evaporative cooling in middle-humidity areas. 【关键词】 蒸发冷却; 机械制冷; 风机盘管; 气象参数; 运行时间 【Key words】 Evaporative cooling; Mechanical refrigeration; Fan coil; Meteorological parameter; Run-time
