摘　　要：本文通过对R407C制冷剂房间空调器换热器分别采用顺流和逆流两种布置方式的定性、定量分析和比较,指出,采用逆流布置方式能够强化换热器的换热性能,而且,换热器排数越多,采用逆流布置方式也就更容易接近真正的纯逆流,换热能力提高的幅度也就越大。By the analysis and comparison between the parallel flow mode and the counter - flow mode used in heat exchangers of the R407C room air conditioner, the paper points out that counter -flow mode has a better performance of the heat transfer than that ot the parallel flow mode. It is also shows that the more rows in heat exchangers has the better performance by using the counter - flow mode, as it is more similar to the real counter - flow.
