PURPOSE:To improve an efficiency of thermal recovery by a method wherein a part of hot water is cooled by a pressure reduction evaporator to make a cold heat source and at the same time evaporated water from the pressure reduction evaporator is guided to a humidifier filled with suction type non- organic chloride and sucked in it, heat exchanged with non-organic chloride of suction type of which temperature is increased to make a hot heating source. CONSTITUTION:An evaporator 14 is reduced in its pressure by a pressure reducing pump 22. A part of hot water 10 is fed to the evaporator 14 through a valve 12, evaporated under a reduced pressure and the hot water is cooled and taken out at 46 as a cold heat source. The evaporated water 44 is alternatively supplied to the two heaters 30 through changing-over of valves 28 and 42. In turn, remaining hot water 10 is supplied to one of the humidifiers 30 through a valve 28. The water suction type non-organic chloride in the heater 30 supplied with evaporated water 44 sucks water to increase its temperature, so that hot water 26 to be supplied is heated to make a hot heating source. In turn, the non-organic chloride saturated with sucked water in the humidifier 30 to which no evaporated water is supplied is regenerated during this process. With this arrangement, it is possible to improve an efficiency of recovery. |
