Description
Technical field
The present invention relates to the regional heating field, relate in particular to a kind of district heating household metering control station and regulate and control method thereof.
Background technology
Regional heating and household-based heat metering are the important development directions of energy-saving and emission-reduction.Existing electric flow control valve and temperature controller on the market, add the system that heat meter is combined, but in present system, people are electric flow control valve and temperature controller combination, come the flow of adjust flux control valve by the difference of measuring indoor temperature and design temperature, thereby the indoor temperature in control house, and heat meter is just because the heat that metering user uses.This traditional temperature control mode, actual indoor temperature fluctuates in above and below one of design temperature larger temperature range.When the indoor temperature of reality when being higher than design temperature, be that overshoot is overheated, cause the waste of heat, when the indoor temperature of reality when being lower than design temperature, be that less stress is excessively cold, reduced comfortableness.Although the existing desired temperature at times of present temperature controller, it only is the function of time, can not have nobody to carry out intelligence according to family and regulate.For example system is at the design temperature of nobody time period, because just in time someone is in this time period of some day, then existing system can not change to people's desired temperature to desired temperature from unmanned desired temperature automatically.
Summary of the invention
The object of the invention is to overcome the shortcoming of existing regional heating household metering regulator control system and provide a kind of simple in structure, reliably and with long-term, can effectively improve a kind of district heating household metering control station and the regulate and control method thereof of the efficient of whole regional heating.
Purpose of the present invention and solve its technical problem underlying and realize by the following technical solutions: in the district heating household metering control station inlet channel 1 is arranged, inlet channel temperature sensor 5 has been installed on the inlet channel 1, on the water return pipeline 2 in the district heating household metering control station electric flow control valve 3 has been installed, heat metering parts 4 and water return pipeline temperature sensor 6, heat metering parts 4 link to each other with water return pipeline temperature sensor 6 with inlet channel temperature sensor 5, control assembly 7 and indoor temperature transmitter 8, outdoor temperature sensor 9, indoor occupant detector 10, electric flow control valve 3, heat metering parts 4, inlet channel temperature sensor 5 links to each other with water return pipeline temperature sensor 6.
When indoor occupant detector 10 detected the indoor people of having, no matter temprature control unit was in what period, its desired temperature all automatically adopt the indoor people's of having time period corresponding people's desired temperature arranged.
Keeping indoor temperature is to calculate that to remain on the required heat of this temperature be Q in the control method of design temperature
Consume=A-bTout, wherein A is a coefficient relevant with their mean heat transfer coefficient with each room design temperature, b is a coefficient relevant with the mean heat transfer coefficient in house, and Tout is outdoor temperature, then supplies with the heat Q in house by calorimetry part measured zone heat supply pipeline
Supply, pass through Q
Consume=Q
Supply+ Q
Other≈ Q
SupplyFormula is opened to corresponding flow position to electric flow valve, thereby the heat that the heat that realization consumes equals to obtain has kept the stable of indoor temperature.
As indoor design temperature Tset with indoorly record temperature T measure not simultaneously, calculate the heat that reaches the required increase of design temperature Tset or add minimizing:
Q
diff＝C(T
set-T
measure)
Then, measure Q according to heat metering parts 4
SupplyIncrease or reduce the flow of regulating electric flow control valve, wherein C is a coefficient, can be by after being installed to district heating household metering control station in the house, a plurality of different T that is recording
MeasureThe calorie value of value and the corresponding increase that is measured by heat metering parts 4 is done the curve match and is got
The present invention as can be known from the above technical solutions, is according to house how many heats of needs to control with regard to the method for supplying with how many heats compared with prior art, and it is overheated can not occur, so its energy-saving effect is better, can not occur coldly, so its comfortableness is higher.It is simple in structure, reliably and with long-term, can be widely used in direct-type regional heating system, has good market prospects.
Below further specify beneficial effect of the present invention by the specific embodiment.
