描述了在换向阀周围的四个站测量制冷剂焓的技术。热流平衡用于计算通过阀门结构材料传导的热流。提出了一种减小内漏对计算传热影响的分析方法。给出了两个主要制造商的6吨阀门和10吨阀门的数据。得出的结论是，制冷剂焓变是一种可接受的测量换向阀传热的方法，其内部泄漏率目前在行业中是典型的。 单位:双引文:研讨会，ASHRAE交易，1986年，第92卷，pt。2B，波特兰，或

Techniques for measuring refrigerant enthalpy at four stations around a reversing valve are described. A heat flow balance is used to calculate heat flow conducted through the valve materials of construction. An analytical method for minimizing the effects of internal leakage on the calculated heat transfer is developed. Data are presented for 6-ton valves and 10-ton valves from two major manufactures. It is concluded that refrigerant enthalpy change can be an acceptable measure of reversing valve heat transfer with internal leakage rates currently typical in the industry.Units: Dual
