Abstract
PURPOSE: To prevent malfunctions and to improve the operating efficiency of a condenser by controlling the first valve when the comprehensive cooling water quantity signal based on the difference between the setting value of the cooling water quantity and an actual cooling water quantity is below the highest limit of the quantity of the cooling water circulating in the condenser, and controlling the second valve by the excess when the comprehensive cooling water quantity signal is above that.
CONSTITUTION: A flow rate setting value Q1 is determined by a flow rate setting circuit 101, and the difference Q3 between the flow rate setting value Q1 and a comprehensive actual flow rate Q2 is obtained by an adder 102. Base on the difference signal Q3, a comprehensive flow rate command value Q4 is output from a flow rate command circuit 103. A flow rate command element 104 for the condenser inlet valve outputs a flow rate command signal Q5 proportional to the signal Q4 until being restricted by the inlet valve and the condenser cooling pipe and restricted so as to be a constant value after that. When the output of the condenser inlet valve reaches the maximum, a flow rate command element 105 for the condenser bypass valve outputs a bypass pipe flow rate command value Q6. Based on the command values Q5 and Q6, valve opening controllers 108 and 111 output valve opening values η1 and η4, based on which a condenser inlet valve 3A and a bypass valve 9A are controlled.
