Energy-saving and water-saving system and control method thereof

Abstract

The invention relates to an energy-saving and water-saving system and a control method thereof. The energy-saving and water-saving system comprises an induction type temperature control valve and a cold water recycler, wherein the induction type temperature control valve comprises a first control circuit, an inductive probe, a temperature sensor and an electromagnetic valve; the inductive probe is connected with the first control circuit and is used for detecting whether people exist; the temperature sensor is used for detecting the temperature of water in a hot water pipeline of a hot water supply source; the electromagnetic valve is used for controlling water in the hot water pipeline to flow back to the cold water recycler; the cold water recycler comprises a second control circuit, a vacuum cavity, at least one cold water recycling pipe as well as a water and air sucking pump and a detector which are connected with the second control circuit; the cold water recycling pipe is connected with the hot water pipeline through the electromagnetic valve; the water and air sucking pump is used for delivering water in the vacuum cavity to the hot water supply source through a cold water inlet pipe of the hot water supply source or extracting air in the vacuum cavity and discharging the air out of the vacuum cavity; the detector is used for detecting pressure of the vacuum cavity or detecting the water level in the vacuum cavity; the hot water pipeline is further connected to a water outlet. According to the energy-saving and water-saving system and the control method thereof, energy and water are saved, and further, automated control is realized.

Description

technical field [0001] The invention relates to an energy-saving and water-saving system and a control method thereof. Background technique [0002] Whether you are taking a bath, washing your hands or washing your face, when you turn on the hot water faucet at home, the cold water in the pipeline always flows out first, and the hot water will slowly flow out after all the cold water is drained. Unacceptable to urbanites. Especially in winter, every time I turn on the faucet before taking a bath, I jump out of the shower room and dare not go in until water vapor appears on the shower partition; for large apartments, duplex buildings, villas, hotels, etc., it takes several minutes to wait for hot water to come out each time , Waste of water resources is also a waste of precious time... According to incomplete statistics from professional organizations, a 120-square-meter family of three spends 730 minutes waiting for hot water every year, and about 40 tons of "front-end cold...
