摘要：PURPOSE:To perform effective utilization and proper processing of exhaust heat by providing an absorbing cold water machine of utilizing steam as a heat source and a heat radiating system for radiating surplus heat of the steam to the outside. CONSTITUTION:Vapor exhaust heat from a fuel cell D is converted into heat by an absorbing cold machine of a fuel cell exhaust heat utilizing system S and consumed in a room cooling load 67. Here is decreased the room cooling load, and when detected a cold water temperature decreased by a cold water temperature detector 90, a vapor bypass solenoid valve 71 is opened simultaneously with interrupting a vapor supply solenoid valve 70, to further open a shutoff electric motor valve 74 of a cooling water pipe 62 connected to a vapor radiating heat exchanger 50, and to transmit heat of vapor to a cooling water side radiated to the atmosphere by a cooling tower 69. When the cold water temperature rises by again increasing the room cooling load, the solenoid valve 71 is closed by a signal from the detector 90 and also opening the solenoid valve 70, to perform resetting to the before-mentioned cycle. In this way, exhaust heat vapor can be effectively utilized.
