Document Type and Number:
Japanese Patent JP7100423
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cold water circulation system capable of saving power.SOLUTION: A control device 20 (a) determines whether an alarm signal is transmitted or not, that is, whether a management condition is satisfied with respect to management items or not (S27), and (b) determines whether a cold water temperature in a bypass pipe 13 is less than an upper limit value in a predetermined temperature range or not, that is, whether a detection temperature of a first cold water temperature sensor S3 satisfies a capability condition or not. Then the control device 20 executes a remaining heat operation processing to operate an air conditioning device 10 in a pipe remaining heat operation mode, when at least the management condition and the capability condition are satisfied. Thus a cold water circulation system capable of further saving power, can be provided.SELECTED DRAWING: Figure 4
