Document Type and Number:
Japanese Patent JP2019027644
Kind Code:
A
Abstract:
To provide a waste heat utilization system capable of effectively utilizing heat of hot water forcibly drained from a hot water storage tank.SOLUTION: A waste heat utilization system 2 includes: a hot water storage tank 10; a heat recovery device 12 for recovering waste heat of a fuel battery 3 and heating the water in the hot water storage tank 10; a radiator 52 provided at an air supply port from which 24-hour ventilation system takes in the outside air; circulation circuits 31, 32, 43, 44, 45 in which hot water and water circulate via the radiator 52; a circulation pump 33; a pouring part 39 for pouring hot water and water in the circulation circuits; a discharge part 42 for discharging the hot water and water in the circulation circuits to a bathtub; and a control part 48 which controls the execution of forcible drainage processing in which, in the case where there is a request to forcibly drain the hot water in the hot water storage tank 10, the hot water discharged from the hot water storage tank 10 is poured into the circulation circuits, and then, it is circulated in the circulation circuits, the temperature of the hot water is lowered by heat radiation by the radiator 52 and the hot water is discharged into the bathtub 5.SELECTED DRAWING: Figure 1
