Abstract
PURPOSE: To avoid the lowering of the efficiency of compressor as well as prevent the occurrence of drain by the system in which the cooling performance of intermediate cooler is regulated according to the suction condition of the working gas in compressor.
CONSTITUTION: The suction pressure, suction temperature, intake, and suction humidity in the portion 40 are measured by the measurers 16, 17, 18 and 30, and from the measured values, the amount of vapor A contained in the intake gas is claculated by the arithmetic unit 41. At the same time, the pressure and temperature of discharge gas from the intermediate cooler 13 is measured at 42 and from the measured value and intake amount measured, the amount of vapor B to be contained when the humidity is 100% in the discharge gas from the intermediate cooler 12 is calculated by the arithmetic unit 43. And, on these calculated values A and B, the controller 21 sends forth the operating signal 39, the water supply valve 15 is closed or opened, and the cooling performance of the intermediate cooler 12 is controlled. Thus, the occurrence of drain and the lowering of the efficiency of compressor can be prevented.
