HOT AND COLD WATER AUTOMATIC CONTROL SYSTEM

摘要

PURPOSE: An automatic hot and cold water control system is provided to reduce water waste by circulating cold water to a heat exchanger. CONSTITUTION: An automatic hot and cold water control system comprises a cold-water supply pipe(10), a central column switch(20), a hot water supply pipe(30), a mixed solution temperature control valve(40), a mixed solution pipe(50), a mixed solution temperature sensor, a water ring, a water circulating control valve(80), water circulating temperature sensor and a controller(90). The cold-water supply pipe supplies a cold water flowing through a main cold-water supply pipe(12). The central column switch uses the thermal medium flowing from an external facility. The mixed solution temperature sensor is installed on the mixed solution pipe. The water ring is communicated in the mixed solution pipe.
