Document Type and Number:
WIPO Patent Application WO/2010/134770
Kind Code:
A2
Abstract:
The present invention provides a cold/hot water supply system for public facilities, wherein residual water in a pipeline circulates to a hot water boiler through a circulating water pipe instead of being drained through a faucet, the circulated water is heated, and the hot water is adjusted by a thermostat and a geared valve to the temperature set by a user such that mixed water with less variations in temperature can be stably supplied. The cold/hot water supply system of the present invention is provided with an improved control unit for preventing the immoderate operation of the thermostat and the geared valve, for supplying water having a temperature set by a user to each zone, for preventing a sudden variation in temperature during the reignition of the hot water boiler, and for providing information via a screen and/or a voice from a speaker of a control panel upon reaching the preset temperature, thereby improving convenience for the user.
