"Temparature-Adjustable Water Supply System" ABSTRACT OF THE DISCLOSURE A temperature-adjustable water supply system used for supplying an appropriate temperature water to a water-using object. The system comprises a mixing device coupled to a hot water supply passage and a cold water supply passage for respectively introducing hot water and cold water thereinto and coupled to a water mixture supply passage for supplying the mixture of the hot water and cold water toward said water-using object. The mixing device includes a flow rate adjusting valve assembly for adjusting the mixture ratio of the hot water and the cold water discharged into the water mixture supply; passage. A temperature sensor is provided so as to sense the temperature of the water mixture and a temperature setter for setting a target temperature. Also included in the system is a control unit which calculates a temperature deviation on the basis of the temperature of the mixture sensed by the temperature sensor and the target temperature set by the temperature setter. The control unit determines a control amount to the flow rate adjusting valve assembly on the basis of the calculated temperature deviation so as to provide an appropriate mixture ratio of the hot water and the cold water.
