Road is equipped with circulator；It is characterized in that, when using hot water for the first time, the circulator runs a setting duration T, described
The setting method of setting duration T includes following several any one: 1) detecting the circulator using water flow sensor
Water flow q when operation, according to formulaSetting duration T is calculated；The pipeline section product of behalf circulation loop, L
Represent the farthest length of pipe with water spot to water heater；2) it is detected when the circulator is run most using temperature sensor
The remote temperature value for using water spot, when the temperature value to setting value when write down circulation duration, which is to set duration T.
As a further illustration of the above scheme, the water flow sensor is arranged in the circulator.
As a further illustration of the above scheme, the water flow sensor or the temperature sensor and a controller connect
It connects, setting duration is obtained using the controller and controls the water circulating pump of the circulator by long running when setting.
As a further illustration of the above scheme, the controller is integrated in the circulator, or, the controller
For the water heater master controller being arranged on water heater.
As a further illustration of the above scheme, when the circulator is arranged on the water inlet pipe.
As a further illustration of the above scheme, being equipped with thermostatic valve between the water inlet pipe and the outlet pipe.
As a further illustration of the above scheme, the circulator is arranged on the outlet pipe.
As a further illustration of the above scheme, the circulator is arranged close to described with water spot, the temperature sensing
Device is arranged in the circulator.
As a further illustration of the above scheme, the water heater is electric heater or solar water heater or heat-pump hot-water
Device or air energy water heater.
The beneficial effects of the present invention are:
One, when using hot water for the first time, circulator runs a setting duration, to make to stop when hot water arrival water spot
It only preheats, hot water is avoided to enter cold water pipe, avoid useless cold and hot mixing.
Two, water flow is detected using water flow sensor, and is combined corresponding formula to calculate and obtained setting duration, setting
Duration precise control, versatility are good.
Three, detect the farthest water temperature for using water spot using temperature sensor, and according to it is farthest with the water temperature of water spot change come
Determine setting duration, conveniently the automatic running when using water next time, intelligence degree are high.
