Abstract

PURPOSE: To control the number of water cooler-heaters according to the measured water quantity by providing the cool and hot water return pipes from each charge with water meters.
CONSTITUTION: When the whole system is in operation, all water coolers and heaters 2, 4, all pumps 8, 12, 14 work, load 16, 18 perform the room temperature regulation. Here, for example, if load 18 stops the room cooling requirement, the pump 14 stops and an electromagnetic valve 22 is shut. At the same time an electromagnetic valve 24 is opened to bypass the surplus cooling water in a cold water reservoir 10. At this time the water meter 26 detects that the cooling water quantity of the return pipe is dropped down to 50% and the water cooler 2 of the first order is made to stop its operation by a step signal generator 28 and to perform the cooling operation with the water cooler 4 only.
