Title:
HOT WATER STORAGE UNIT AND COGENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2015075244
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a hot water storage unit capable of being continuously operated without stopping a heat source device such as a fuel cell and to provide a cogeneration system which supplies hot water using waste heat of the heat source device.SOLUTION: A hot water storage unit: measures or estimates a temperature of water supplied from a hot water storage tank 21 to a heat source device using a temperature sensor; sucks in external air (fresh air) from an outside of a cover 21a using a cooling device 21c in accordance with a measurement result; upwardly flows the sucked air in a space 21d along an external surface of a tank body 21b (side face section); and exhausts the sucked air out of the cover 21a through an opening 21a0. Thus, the hot water storage unit efficiently cools water to be supplied to a heat source device and can be continuously operated without stopping the heat source device. In addition, the hot water storage unit does not require a radiator for cooling the water supplied to the heat source device and does not need discharge of high temperature hot water and a supply of cold water. Therefore, the hot water storage unit can be miniaturized, save electricity and reduce a production cost.
