Abstract

PURPOSE:To make a high-reliability monitor inspection possible even at a high temperature, by controlling the quantity of cooling medium, which is sent to a vehicle with a plant monitor device mounted thereon, by the signal from a temperature detecting element installed in the vehicle with the plant monitor device mounted thereon. CONSTITUTION:A cooling medium 16 boosted by a compressor 24 in a cooling vehicle 13 is sent to a TV vehicle 1 and a control vehicle 21. A gas 17 of an elevated temperature was used for cooling the device is recovered to the cooling vhicle through a valve 25. In this case, signals 50 indicating temperatures detected by means of thermostats 18 incorporated in the TV vehicle 1 and the control vehicle 21 are sent. A valve control circuit 27 receives these signals 50 to operate, and a valve opening signal 43 is sent to control the opening of the valve 25. As the result, circulating flow rates of the cooling medium 16 and the gas 17 are controlled efficiently.
