近年来，冰箱的能效越来越高。然而，关于冰箱除霜的研究却很少。冰箱通常仍然使用电阻加热元件进行除霜。在亚洲，尤其是在日本和台湾，许多冰箱冷凝器连接在冰箱侧板上，通过侧板散热。这种设计节省了冰箱空间，但不是很节能。使用典型的热泵式循环反转进行除霜会导致冷凝器面板变冷，水分可能会在侧板表面冷凝并流到地板上。设计了一种新型的反向循环系统，使冷凝器完全旁通，从而避免侧板上的湿气凝结。 定性实验室测试数据表明，反向循环除霜概念按预期工作，并且发现其比传统的直接电加热除霜方法更节能。单位:双引文:ASHRAE交易，第116卷，第。2010年奥兰多

Refrigerators have been becoming more energy efficient in recent years. However, there is little research work on refrigerator defrosting. Refrigerators generally still use electrical resistance heating elements for defrost. In Asia, particularly in Japan and Taiwan, a lot of refrigerator condensers are attached to the refrigerator side panels, with heat dissipation through the panels. This design saves refrigerator space, but is not very energy efficient. Applying a typical heat pump type cycle reversal for defrosting would cause the condenser panels to become cold, and moisture might condense on the surface of the side panels and run down to the floor. A novel reverse cycle system was designed to completely by-pass the condenser, thus avoiding moisture condensation on the side panels. Qualitative laboratory test data indicated that the reverse cycle defrosting concept worked as expected, and it was found to be more energy efficient than the conventional direct electric heating defrost method.Units: Dual
