<P>PROBLEM TO BE SOLVED: To allow heat recovery from cooled fluid with simple structure while preventing breakage of a membrane, in a water supply system using a membrane type deaeration apparatus. <P>SOLUTION: A first water supply path 14 is opened from the membrane type deaeration system 8 to a water supply tank 3. The first water supply passage 14 is not provided with a valve for cutting off a flow in a forward direction from a deaeration apparatus 8 to the water supply tank 3. A second water supply path 15 is branched from the first water supply passage 14 to supply water to the water supply tank 3 through a heat exchanger 18 with the cooled fluid. A water level sensor 13 monitors a water level of the water supply tank 3. When the water is supplied from the deaeration apparatus 8 to the water supply tank 3 based on a detection signal of the water level sensor 13, the water can be supplied through a second water supply path 15. <P>COPYRIGHT: (C)2013,JPO&INPIT |
