Abstract

Abstract:

A calculation method of an air-to-air thermosyphon heat exchanger was reported in this paper. The face velocity, number of rows and inclination angle of heat exchanger were tested and studied in an air enthalpy type psychrometric calorimeter including indoor and outdoor chambers. The error of the calculation method and experimental data was within 15%. Thus, the calculation method can be applied in engineering design of the air-to-air thermosyphon heat exchanger.

Key words: thermosyphon heat exchanger, heat recovery, effectiveness of heat exchanger, heat pipe, face velocity

摘要：

为探讨空气-空气整体式热虹吸管换热器的换热性能,利用换热器效能计算公式对其进行计算,并在焓差试验室对空气-空气整体式热虹吸管换热器的迎面风速和换热器管排数进行了测试和研究。结果表明,换热器的计算方法与试验数据最大误差在15%以内,且最大误差出现在温度效率较高时。因此,计算方法适用于工程设计计算。
