摘　　要：以现行标准规范为依据,阐述了由于各型号风机盘管本身水压降差异大以及电动两通阀选用不当而导致实际工程中同程系统并联管路水力严重失调问题。并通过实例计算,具体说明如何通过合理的电动两通阀选型、计算实现水力平衡,并对可能出现的问题及注意点进行了探讨。Based on the current criteria,issues about hydraulic imbalance caused by the pressure drop of fan coil units and improper selection of two-way electric valve in reverse return system were brought up.A proper balance design was emonstrated by a detailed calculation of two-way electric valves.And potential problems and notes were discussed according to the actual situation.
