Based on the steady state distributed parameters model of the condensers which was put forward in the previous related reference the heat transfer and flow characteristics of four different two-rows condensers which used the refrigerant replacement(R407C,R410A,R134A)of R22 were studied.
结果表明:采用R22的3种替代工质时,冷凝器性能的变化规律基本一样,4种流路布置中,在随着管内冷媒流量的变化和随着冷凝器迎风面风速的变化两种工况下,逆流换热效果最好,其次是错流,顺流最差;在与R22为工质的冷凝器性能比较中,采用3种替代工质的冷凝器换热量及进出口压降的变化趋势基本一样;在3种替代工质中,R410A性能较好,换热量最大、压降最低,但其冷凝压力比R22高出60%左右,R134A压降较大,这两种都不是理想替代物,而R407C与R22在换热量及压降方面最为接近,是其理想的替代工质。
