摘　　要：实测不同型号传统风机盘管在标准工况下的单位输入功率供冷量,以及某型号传统风机盘管(FP-102)在高温工况下运行的供冷量和水阻压降。对风机盘管在高温工况下的供冷量、水阻压降的计算公式进行拟合,得到修正公式。提出在不同进水温度下的最优运行参数,分析传统风机盘管与高温冷水机组的配合使用。传统风机盘管在高温工况下运行时,即使在最优运行参数下运行,单位输入功率供冷量很低,需要根据高温工况特点,设计新型的结构形式。The cooling capacity per unit input power of different types of fan coil units under the standard condition as well as the cooling capacity and water resistance pressure drop of a fan coil unit （ FP- 102） under high temperature conditions are tested. The calculation formula of cooling capacity and water resistance pressure drop of fan coil units under high temperature conditions are fit, and the correction formula is obtained. The optimal operation parameters under different inlet water temperatures are put forward. The combined application of a traditional fan coil unit and a high temperature water chiller is analyzed. Under high temperature conditions, even if using the opti- mal operation parameters, the cooling capacity per unit input power of traditional fan coil units is very low, and a new structure form needs to be designed according to the characteristics of high temperature.
