热泵式热水机组工作原理利用设备内的吸热介质（冷媒）从空气或自然环境中采集热能，并通过热交换器使冷水迅速提温，同时排放出冷气。避免了传统太阳能产品在阴雨天气、夜晚不能工作的缺陷，只要外界温度在1-15度以上就能正常工作，故能更加高效、节能，同时可不占露天空间，安装简捷、使用灵活。机组构成运行模式及原理热泵式热水机组是由一个制冷循环组成，包括主机和冷凝器两部分。其中主机部分包括蒸发器、风扇、压缩机及膨胀阀；冷凝器为内放冷凝盘管的保温箱。制冷剂在蒸发器内吸收外部空气的热量，通过热泵循环在冷凝盘管内释放热量，加热水箱内的水。水箱的保温层采用闭孔橡胶海绵或聚氨脂发泡，且具有良好的保温性能。热泵机组设备内专置一种吸收热媒质―――冷媒，它在液化的状态下常温低于零下20度，故此，它与外界温度存在着温差，冷媒吸收了外界的温度，在蒸发器内部产生压力并蒸发汽化，通过热交换器（热泵）的工作，使冷媒从汽化状态转化为液化状态时，客观存在的热量便释放给水罐中的储用水。电只用在使热能释放出来，而不是用在直接加热，故用电量很少，在夏季气温高时，生产一吨热水约损耗5-6度电，冬季寒冷的天气约损耗20-25度电，全年平均不超过15度电。产品的特点热能来源广泛，包括阳光、雨水和空气。无论白天、黑夜；不管晴天阴天、刮风下雨、下雪都能照常工作，不受气候影响，一年四季全天候照常工作。可放在你指定的任何地方，不影响建筑物外观，只需很少空间，无需直接光照，安装非常容易。可露天摆放，也可放置在不显眼的角落或地库里，并可实现无人操作，全自动控制温度供水。适用范围非常广泛：可用于酒店、餐馆、工厂、学校、医院、桑拿浴室、美容院、游泳池、温室、养殖场、洗衣店、家庭等，可单独使用，亦可集式使用，不同的供热要求，可选择不同的产品系列和安装设计，同时还可免费获取冷气，从任何角度满足你的要求；出色的无CFC绝缘，只有2%热损失，可以更长的时间保持水温，热效率超出其它常规太阳能产品的确倍。冷媒不含氟利昂，无任何废气、废水排放，绝对环保，水罐中无燃气或电气推动，绝对安全。节能效果明显，与使用燃油、燃气、电、媒等相比，至少可节省75%以上的运行费用，让您轻松收回成本。产品特性高效节能：该热水机组以空气不低温热源制取热水，耗电量仅为电热水器的1/3-1/4；同燃煤、油、气热水机组相比，可省75%的运行费用。
