COOLED WATER IN HOT WATER PIPE REUSE SYSTEM UTILIZING WATER SAVING FAUCET HAVING DRAIN FUNCTION

摘要

Cold water recycling system in a hot water pipe using a water-saving faucet having a drain function associated with the present invention is connected to the first cold water pipe, a hot water pipe supplied from the boiler and a drain pipe for discharging the cooled hot water in the hot water pipe A faucet control unit configured to open or close the mixed or mixed water of cold water and hot water or to discharge the cooled hot water in the hot water pipe; A drain valve disposed on the drain pipe and configured to open and close water in the drain pipe; A pressure sensing unit disposed on the drain pipe between the power receiving control unit and the drain valve and configured to sense a water pressure in the drain pipe; And a controller configured to open or shut off the drain valve according to the pressure in the drain pipe sensed by the pressure sensing unit.
