  1. The research results show that the counter - flow condensers have a better performance than that of other arrangements in single - circuit condensers, and that branch flow should be adopted in multi - rows condensers to decrease the pressure drop and increase the heat transfer capacity, and that the influence of gravity force can not be ignored, and that there must be an optimum refrigerant mass flow which can make the condenser perform best when the air velocity is constant while there must be an optimum air flow which can make the condenser perform best when the refrigerant mass flow is constant

    研究結果表明，單迴路冷凝器中，逆流布置換熱效果最好，叉流其次，順流最差；多排管冷凝器應盡可能採用分流方式，以減小壓降，增強換熱；布置冷凝器流程時，重力的影響不可忽略；當風量不變時，必然存在一最佳製冷劑流量使冷凝器性能達到最佳；當製冷劑流量保持不變時，也相應存在一個最佳風量使冷凝器性能最佳。
  2.
