摘要
以北京某医院工程为例,介绍了温度湿度独立控制系统在医院空调中的适用性和优势,得出完全由新风来承担室内的湿负荷,室内盘管干工况运行可以有效地解决医院空调空气污染,尤其是集中空调自身带来的室内空气污染问题,大大改善室内空气质量。采用高温冷水机组COP提高约30%,利用高温冷水对新风进行一级表冷,低温冷水进行二级表冷的双盘管热回收新排风机组可以减少能耗约13%,两级热回收对新风进行预冷和再热可进一步降低新风的处理能耗。
Taking a hospital building in Beijing as an example,presents the applicability and technical advantage of temperature and humidity independent control air conditioning system.Obtains that the air contamination problem of hospital air conditioning,especially caused by central air conditioning system itself could be effectively solved if moisture load is completely undertook by fresh air and fan coil unit is in the mode of dry operation,and indoor air quality greatly improves.Meanwhile,with high temperature water chiller,COP increases by approximately 30%.Double cooling coil heat recovery fresh air handling unit using high temperature chilled water for fresh air primary surface cooling and cold temperature chilled water for secondary surface cooling can reduce energy consumption by approximately 13%.Pre-cooling and reheating fresh air using two-stage heat recovery coil can further reduce the fresh air handling energy consumption.
