<p>PURPOSE:To obtain a device for exhaust heat utilization which improves the heat exchange efficiency and enables stepping up compactness as regards a second heat exchanger for the heat exchange for equipment utilizing exhaust heat. CONSTITUTION:There are provided a load sensor 14 which detects variation of the load of an electric apparatus 2, first and second temperature sensors 4, 5 which detect the temperature of cooling water on the side of the cooling water inlet and on the side of the cooling water outlet respectively of a first heat exchanger 3, a three way valve 20 by which the flow of cooling water from the outlet side of the first heat exchanger 3 is directed in a fork to a second heat exchanger 6 and to a cooling tower 8, an inverter 22 which effects variable speed operation of a pump 11, and a controller 23 which from output signals from the load sensor 14 and the two temperature sensors 4, 5 performs the operation and estimates changes in the temperature of the electric apparatus 2 and outputs control signals respectively to the three way valve 20 and the inverter 22.</p> |
