制冷系统中存在水份,将引起不良后果,例如锈蚀、形成油泥与冻结节流装置。过去用于大型制冷设备的制冷剂干燥器都存在成本过高的缺点,而小能量制冷设备的制冷剂干燥器。一股都采用化学干燥剂,典型的硅胶与活性铝。这种干燥剂在吸收水份达到饱和时,必须进行更换,这样就增加设备的复杂性、成本与维护工作,也使制冷剂受到损失。 The presence of moisture in the refrigeration system will cause undesirable consequences such as corrosion and formation of sludge and freezing throttling devices. In the past, refrigerant dryers for large refrigeration equipment all had the disadvantage of being overly costly, whereas refrigerant dryers for small energy refrigeration equipment. A common use of chemical desiccant, a typical silica gel and activated aluminum. This desiccant must be replaced when water absorption is saturated, increasing the complexity, cost, and maintenance of the equipment and also causing refrigerant losses.
