Wherein, the indoor temperature regulation device comprises temperature collect module, display module, communication module, computing module; Temperature collect module, display module, communication module are connected with computing module respectively.Wherein computing module is calculated, is analyzed, is judged the temperature gathered, process, finally provide rational indoor temperature as the heat sharing basis, avoid " temperature fluctuation ", " mid-winter ", " abnormal cooling " impact on heat sharing, control motor-driven valve by control module and regulate continuously.
Motor regulated valve can be done to regulate continuously to flow in controlled pipeline, and it is controlled by the indoor temperature regulation device.
The course of work is as follows:
Be arranged on the indoor indoor temperature regulation device 1 of hot user, automatically control and be arranged on the motor-driven valve 2 on heating pipeline, room temperature during lower than design temperature motor-driven valve open greatly, the room temperature rising; In the time of will reaching design temperature, motor-driven valve turns down, and room temperature descends gradually, makes and so forth indoor temperature remain in the scope of setting.

2 explanations:
(1) adopting the outside air temperature 6 in-site measurement outdoor temperatures of popping one's head in is emphasis of the present embodiment.Calorimeter 5 is measured a building heat, and 6 of outside air temperature probes are measured this building peripheral temperature and got final product.Calorimeter 5 is measured whole community heat, and when control range is larger, temp probe can be established several more, is averaged the temperature value in integrating instrument.Should be noted that, only have with the outside air temperature on-the-spot thermometric of popping one's head in, just can guarantee that parameter is true, calculate accurately, heat sharing is fair and reasonable, and any data that obtain by indirect mode (as by empirical data and indirect datas such as meteorological data, design parameter, inverse derivations) are all inaccurate and worthless.
(2) indoor temperature regulation device 1 and hand-held remote controller 3 have " key is controlled " function.Can show date, temperature controlling mode: standard, sleep, period, indoor and outdoor temperature, the information such as heat consumption, valve and temperature control state.One of the indoor temperature regulation device each household of minute family temperature control, one, every room of measure by door.Motor regulated valve arranges according to indoor temperature regulation device quantity.
Adopt the present embodiment " temperature differential method " and conventional heat measuring method to Beijing, Harbin, Qingdao, etc. urban heating season heat consumption done detailed calculating and analysis, and compare and verify with regular thermal technology's result of calculation, its result " temperature differential method " is coincide with the data that regular thermal technology calculates, and has proved correctness, science, advance, the reasonability of " temperature differential method " methodology.
Below to carry out the calculated examples of heat sharing with the present embodiment:
" temperature differential method " heat sharing computing formula is as follows:
(1) computing formula of indoor/outdoor temperature-difference:
ΔT＝Tn-Tw (1)
In formula (1), Δ T is indoor/outdoor temperature-difference; Tn is indoor temperature; Tw is outdoor temperature;
(2) Lou Donghuo community total heat consumption is shared the computing formula to each user:
K＝Qz/A1(T1-Tw)+A2(T2-Tw)+…+An(Tn-Tw)
Qi＝K*Ai(Ti-Tw) (3)
It is exactly the total heat consumption Qiz in this user heating season that i user shared to heat adds up at every turn:
In formula (2), (3), (4):
K-heat sharing coefficient: every m
2the heat consumption of every ℃ of indoor/outdoor temperature-difference, unit is W or J;
This period building heat consumption that the Qz-calorimeter records, unit is KWh or GJ;
A1, A2, Ai, An-the 1st, the 2nd, i, nth user's area, unit is m
2;
T1, T2, Ti, Tn-the 1st, the 2nd, i, nth user's indoor temperature, unit is ℃;
The outdoor temperature of Tw-actual measurement, unit is ℃;
The heat that i user of Qi-shares for the i time, unit is KWh or KJ;
Qi1, Qi2, i user of Qin-, the 1st, the 2nd, n period heat consumption, unit is KWh or KJ;
I of Qiz-user heating season total heat consumption, unit is KWh or GJ.
The 24 family periods of Dong Liangge unit, table 1 Shi Mou building are shared heat, are the results of calculating by sharing formula (2) and (3).
Table 1:
K＝110751.55/76.32*(20.3+3)+76.32*(18.2+3)+......+...
＝110751.55/53160.74＝2.083
The 1st user shares heat Q1=76.32* (20.3+3) * 2.08=3704.70W
The 2nd user shares heat Q2=76.32* (18.2+3) * 2.08=3370.8W
By that analogy ... 24 users of .. to the,
It is on all four that the heat that in table 1,24 users share adds up to the heat consumption 110751.55W of a 110751.55W ，Yu building summary table.
Table 2 Shi Gai building the different outdoor temperature of Heating Season, the different room temperatures of user, the apportioned heat of different area and a Heating Season total amount of heat.
Table 2:
In table 2, it is consistent with a building total heat consumption that the user shares the total amount of heat total, and the heat that each user's room temperature difference is shared is different, heat is taken also difference of difference, energy-saving effect.Not according to heat metering heat dissipation energy-saving effect 1.33%-31.33%, do not wait average energy-conservation 16.44%.
By above calculating, proved " indoor/outdoor temperature-difference " science, accuracy and fair and reasonable property as the methodology (temperature differential method) of basis.
For more effective and reasonable, heat is regulated to control, the present embodiment mainly adopts following three kinds of adjustment control methods:
1, motor regulated valve adopts " regulating continuously ", improves operation stability.
In conventional heat measuring method, be all to control temperature by the break-make of electrically operated valve: Open valve when temperature is inadequate, valve-off while reaching design temperature.Valve only has " standard-sized sheet " and " complete shut-down " two states (0,1).The shortcoming of conventional electrically operated valve is:
1) there are the sound, fluid to circulate suddenly during the valve break-make and noise is arranged during cut;
2) heating agent sometimes hot and sometimes cold, expand with heat and contract with cold and easily cause the damage of heating pipe fitting and seal.
3) valve closes the impact of thermal characteristics such as " inertia delay " after " the inertia overtemperature " and valve opening of the radiator of having no progeny, and inevitably produces temperature " overshoot ", inaccurate to room temperature control.
4) flow due to each pipeline is to distribute by a certain percentage according to the resistance coefficient of each branch road, and the change of any one branch road flow all can change the flow of other branch road, and contiguous impact is larger.The size of flow affects the exothermic coefficient of radiator, and the height of exothermic coefficient directly affects the caloric value of radiator, and this is a series of chain reaction.The temperature of heat metering is all automatically to control, and all valves all are in break-make at any time, and the hydraulic regime of system is extremely unstable, all in variation, is difficult to reach design balance at any time, and the heating power operating mode also can be subject to corresponding impact naturally.Widely different even failed fatal reason why that this is " metering indirectly ".
5) valve " standard-sized sheet ", " complete shut-down ", make fluid moment stop flowing with moment, and heating system, facility, pipeline, pipe fitting are impacted and shake, totally unfavorable to system.
6) frequent " standard-sized sheet ", " complete shut-down " of valve, easily cause part " gas is stifled " to cause radiator not hot;
7) the significantly stirring of fluid very easily causes the obstruction of pipeline, valve.
8) motor-driven valve moment of torsion maximum when closing valve and driving valve, the actuator operating current is large, volume large, take electricity.And act frequently, affect service life.
Valve " standard-sized sheet ", " complete shut-down " this irrational controlling and the method for operation, cause system condition to worsen and potential safety hazard exists constantly.
It is to adopt " regulating continuously " to solve the problems referred to above that the present embodiment makes motor regulated valve, and concrete control method is as follows:
Due in the design discharge scope, the radiator caloric value becomes corresponding proportional relation with flow.Change the radiator flow and can regulate and control indoor temperature.
Control motor regulated valve (2) by indoor temperature regulation device (1) and do " regulating continuously ", when room temperature is low, valve raises, and flow system flow strengthens, and heating facility thermal discharge improves, and room temperature rises; When room temperature will reach design temperature, valve pulls back to certain aperture, and room temperature descends gradually, when room temperature will drop to, sets while rolling off the production line, and valve raises again, and so repetitive control is regulated, and room temperature is remained in setting range always.During due to regulating and controlling temperature, valve is opened all the time, and just aperture is different with the control uninterrupted, and moment of torsion is little, electric current is little, volume is little, and operating frequency reduces, and increases the service life.Greatly improved the stability of system operation, improved temperature " overshoot ", the harm of avoiding " on-off type " valve " standard-sized sheet, complete shut-down " to bring to system, guarantee system run all right.Can there is multiple control modes to realize this function, as PLC controls, PID controls, the intelligent means such as fuzzy control, fuzzy.
2, measure indoor temperature by " remove peak valley, be averaging ", eliminate the impact of temperature larger fluctuation.
Height occurs and changes in indoor temperature moment that in use may make for a certain reason to detect, and this " temperature fluctuation " causes collecting temperature inaccurate, makes the clearing of heat expense unreasonable.
Adopt now the method for " remove peak valley, be averaging ", avoided the instantaneous temperature fluctuation to cause the inaccurate of thermometric, can reflect objective, truly indoor temperature.The room temperature signal timing that the indoor temperature regulation device records is to router or integrating instrument transmission, several temperature values that this period will be recorded before transmission deal with, several numerical value by peak and minimum, according to a certain percentage (as the height respectively remove 20%) remove, remaining a certain proportion of temperature value carries out arithmetic average again, and average room temperature is transferred to router or integrating instrument as the foundation of calculating heat.
Table 3
Take table 3 as example, and section has gathered 20 room temperature data at a time, wherein has two for 13.2 ℃ and 14 ℃ of unusual fluctuations temperature values, as, after removing 4 maximum temperatures and 4 minimum temperatures, remaining 60% data are carried out arithmetic average again.Mean temperature before untreated is 17.2 ℃, process is 17.8 ℃ according to " mean temperature " after the exploitation of " removing peak valley; be averaging ", be transferred to integrating instrument as the foundation of sharing heat using 17.8 ℃, improve the accuracy that room temperature gathers, avoided the impact of temperature fluctuation on heat sharing.Occur in the room temperature gatherer process while heating up moment, processing method is also the same.
3, room temperature is carried out to fuzzy control and intelligent decision, the impact of avoiding abnormal cooling and heating up.
Abnormal cooling: if in use deliberately window or make otherwise to cause indoor collecting temperature to descend, will hand over less hot expense, this part heat due to many consumptions of windowing and the heat expense that this user hands over less will be amortized the hot user to other, and this is extremely inequitable.
Mid-winter: if kith and kin's party in family raises because human-body radiating can make room temperature, if reeky soup dish or even chafing dish are arranged again, it is higher that indoor temperature can rise.This owing to not being the heat release of heating facility, but other reason makes indoor heat gain and heats up, if be obviously extremely irrational according to the temperature charge." the party blocked shot, also will hand over hot the expense more? ", no one can accept!
Due to building " thermal inertia " factor, indoor temperature raises or reduces under normal circumstances a process slowly, and in the short time, heave amplitude can be very not large, and rapid drawdown more can not rise sharply.According to these characteristics, can adopt " fuzzy control " intelligent means to be detected, analyze, judge, process indoor collecting temperature, eliminate " abnormal cooling ", " mid-winter " impact on heat sharing.
Principal character when " abnormal cooling ", " mid-winter " occur:
1) intensification or cooling rate are fast, and very short time can reach higher or lower value.
2) intensification or cooling extent are large, far beyond normal temperature control scope.
3) perdurabgility long, far beyond the motor-driven valve regulation and control cycle.
4) have uncontrollability, even if temperature has exceeded the normal regulation scope, temperature controller and motor-driven valve can't be controlled it.
According to above feature, can be judged it and be processed by methods such as fuzzy controls.
Raise and make room temperature rising, downward make room temperature decline that some cycles be arranged by motor-driven valve.Can be judged to be invalid value when following 3 kinds of situations occur temperature value, still calculate by the mean temperature before occurring:
(1) within very short time, the gradient of temperature amplitude is very large, far exceeds the temperature adjusting scope, and the duration regulates and controls the cycle much larger than normal temperature;
(2) after the motor-driven valve rise, room temperature is in the normal rising stage, and room temperature is impossible descend under normal circumstances, if now room temperature descends, as temperature in 1～2 minute just descends more than 2 ℃, can be judged to be abnormal cooling;
(3) after the motor-driven valve downward, room temperature is in normal decrement phase, and room temperature is impossible rise under normal circumstances, if now room temperature rises, as temperature in 1～2 minute just rises more than 2 ℃, can be judged to be mid-winter.
If the special circumstances such as heat supply accident occur, flow system flow, temperature can great changes will take place, and the heat of Lou Dong also can great changes will take place, on each user's impact, is the same, and above determination methods does not affect the Cost Allocation of heat.

Other structures of the present embodiment are identical with embodiment 1.
