Abstract
Lower and upper limit float switches 15a and 15b for detecting the liquid level in high-temperature separator 14, orifice portion 18 and float-associated valve V1 parallel to the orifice portion are provided, with the orifice portion being provided on circulation pipe K2 extending from the gas-liquid separator in a position either upstream or downstream of high-temperature heat exchanger 17. The float-associated valve is closed when the liquid level drops to the lower limit thereof and it is opened when the liquid level rises to the upper limit thereof. During normal operation of the cooling apparatus, the flowing of steam from the gas-liquid separator into the heat exchanging unit can be prevented to ensure smooth passage of the solution. In a diluting operation, the head of the gas-liquid separator suffices to ensure an adequate flow of the solution in spite of the small pressure difference, thereby assuring the diluting operation to proceed smoothly.
