Description
Technical field
The present invention relates to heating system technical field, more particularly, to a kind of heating energy control method based on human body sensing
And device.
Background technology
Domestic at present main heating system is still central heating, but the area carrying out central heating does not often all consider to use
Family demand, blindness extensive style heat supply, not timesharing is uneven regardless of regional heat supply, the heat demand of carrying out, and user side can not simultaneously
Based Intelligent Control room temperature, heating installation whole day is supplied, and temperature is often very high, ventilation windowing, and heat waste is serious.Common interior on market
Control arrangement for heating system has central heating valve, temperature-sensing valve.Central heating valve needs user's Non-follow control, is only placed in open and close shape in most cases
State, operation inconvenience is difficult to energy-saving effect again.And temperature-sensing valve then can automatically adjust heating flow automatic, well room temperature is controlled
In certain limit, but it fails to solve indoor unmanned heating installation to supply the significant wastage causing in the same old way, does not meet today's society energy-conservation
The development trend reducing discharging.
A kind of novel office room energy-saving heater (patent No.: cn 202485102 u) is according to office interior whether someone
And the working time section of people is controlling radiator import three-way magnetic valve, heating in advance or extend heating, but can not meet not
Situation about changing with demand and the personal work and rest rule of user.And the present invention has not only counted interior whether someone,
Also count the indoor occupant mechanicses of 1 ~ 2 week, heating installation use habit, optimal heating temperature, room heating installation has been controlled with this
The YE of entrance and flow control valve, adjust flow and the flow velocity of hot water；The rule of personnel's work and rest simultaneously changes
During change, system also can be adjusted accordingly, and meets the heating demands of people all the time.
