摘要
电厂的集控室与电子设备间空调设备选型时,多为按照指标估算机组制冷量,按照冬季热负荷确定制热量,再按照厂家样本进行选型。论文选择了3个气象参数典型的不同城市,按照逐时法计算夏季冷负荷及冬季热负荷,用焓湿图计算机组制冷量、送风量以及制热量,并对计算结果进行分析。
For the air conditioning system of central control room and electronic equipment room in the power plant, the unitrefiigerating capacityis determined on the basis ofcooling index and the heating capacity is determined on the basis of winter heating load, and then the air conditioning unit is selected according to the manufacturer sample book. In this paper, the summer cooling load and winter heating load arecalculated according to the hourly method and the unitrefrigerating capacity, air supply volume and heating capacity are calculated according to the psychrometric chart, then an analysis has been taken for the calculation results ofthreecitie s with typical mete orologic al data.
