本文重点介绍了板式空气-空气换热器的结构、传热和阻力特性、根据试验台实测数据回归成计算公式与图表、为设计与制造板式空气-空气换热器提供了理论计算方法(适用范围是U_m=1.5～8m/s)、以期对开发空调节能装置的单位以及工厂企业的技术人员有参考作用。 This paper focuses on the structure, heat transfer and resistance characteristics of the plate air-air heat exchanger, the regression of measured data from the test bed into calculation formulas and charts, and the theoretical calculation methods for the design and manufacture of plate air-air heat exchangers. The scope is U_m = 1.5 ~ 8m/s), with a view to the development of air-conditioning energy-saving devices and the factory’s technical personnel have a reference.
