Document Type and Number:

WIPO Patent Application WO/2020/211413

Kind Code:

A1

Abstract:

The present application relates to the technical field of water quality monitoring of water supply systems, and provides a water quality monitoring method for a water supply system, the water supply system, and a refrigeration device. The water quality monitoring method for the water supply system comprises: controlling to convey water to a water outlet pipe of the water supply system; obtaining a water quality parameter in the water outlet pipe; determining whether the water quality parameter reaches a standard; if yes, ending the monitoring; if not, entering the next operation; controlling to drain the water from the water supply system; and repeating the obtaining operation, the determining operation, the draining operation, until the water quality parameter reaches the standard. The method can monitor the water quality parameter in the water outlet pipe in real time, and control to drain the water from the water supply system when the water quality parameter exceeds the standard, thereby avoiding the growth and precipitation of organic matters. Moreover, the method can avoid the drainage and flushing of the water supply system after being not used for a long time, reduce the difficulty of operation, and improve the use convenience of a user.
