多效蒸发淡水装置的工作原理概述
The afterheat , which is collected by recovery devices , in winter can be used as the low level thermal source of heat pump , and in summer can preheat feed water , thus equivalent an economizer . because energy flows in the system so reasonably that energy is used to the most , therefore , its energy conservation effect is significant , and the operating expenditure declines consequently . the sewage can be reused after due treatment , thua it has a certain social and ecological benefit , too
本研究中选用分离式热管装置提供洗浴用水，利用水源热泵装置，一机两用，进行空间供热和制冷，并通过余热回收器对系统内的余热进行回收，冬季可作为水源热泵的低位热源，夏季可对锅炉给水进行预热，起到“省煤器”的作用。这样实现系统内的能量合理流动，从而达到节能的目的，同时洗浴污水经适当的处理后可以回用，因而还具有一定的社会和生态效益。
