Technical field:
The present invention relates to a kind of building heat dissipation metering distributor and metering method, be specifically related to a kind of multi-functional minute family heat and measure allocation manager device and metering method.
Background technology:
Mainly there is following problem in present hot measurement technology:
1. calorimeter method.Establish a summary table at the place, building entrance and do trade settlement, each household is provided with the family table and does heat distribution in the building, according to the reading and the rule of family table the data of statement of account is shared.Its advantage is few to the restriction of user's heat form and facility, and what data comprised contains much information, and can reflect more objectively that the user's uses the enthusiasm condition, the energy consumption of quovis modo changes the increase and decrease that all can be transformed into heat, makes things convenient for the user, helps behavior energy saving, rule is transparent, makes us trusting.Its shortcoming is a system complex, and equipment investment is big, flowmeter especially wherein, and the maintenance workload in later stage is big, and the installing space that takies also greatly to housing market, the especially medium and miniature flat of China, is sayed the use that can't support the family table from economy.
2. Heat distribution meter method.Establish a summary table in the building entrance and make the trade settlement table, a Heat distribution meter is installed on indoor every group of radiator; Reading according to Heat distribution meter is shared the data of summary table.Its advantage is that the required place of installation is less, less than the big flowmeter of maintenance, use simple, shortcoming is to measure the heat dissipation of radiator (radiator), can't measure (as water heater) heat dissipation of other modes with the heating system heating, the poor transparency of rule, its data collecting system is subjected to artificial interference easily indoor simultaneously; On the other hand, hypothesis user temperature is a certain value during its design, and radiator is certain model, may not meet user's actual state, so its error may be very big.Covered actual error because of its rule is opaque.
3. flow temperature method.At consumer heat inlet a summary table is set and makees the trade settlement table, inlet at each household adopts a self-operated flow regulator to replace flowmeter, carry out heat sharing by measuring supply and return water temperature with the flow that flow control valve is set, adopt a triple valve to regulate the room temperature, realized measuring and the adjusting one, because there is not flowmeter, maintenance workload is less.Shortcoming: be equal to hotlist on the hardware principle, but do not adopt the algorithm and the rule of hotlist, simultaneously intervening to the user with thermal process, rule complicated (because intervention) and opaque, simultaneously also because distributing to relate to uses thermal process, so the user is limited many, affinity is poor.

The purpose of this invention is to provide a kind of multi-functional minute family heat and measure allocation manager device and metering method, can realize the time measurement at branch family, flow measurement, heat metering by enough less flowmeters; Measurement simultaneously and adjusting, management, system debug combine together; can monitoring system self whether normal; can help the thermodynamic equilibrium of regulating system; or even the heating power enterprise problem of headache---system's dehydration the most; comprise artificial discharging water and the leakage of system, protect user's investment to greatest extent.
Above-mentioned purpose realizes by following technical scheme:
Multi-functional minute family heat metering allocation manager device, its composition comprises: the female pipe of female pipe and backwater supplies water, one group of user pipe in parallel between the female pipe of female pipe of described water supply and described backwater, each described user manages the connection radiator, described radiator connects smart valve, described smart valve connects indoor temperature setting measurement device, the female pipe of described backwater is gone up total hotlist is installed, connect device for pressure measurement between the female pipe of female pipe of described water supply and described backwater, described smart valve, total hotlist all are connected with master controller with described device for pressure measurement.
Described multi-functional minute family heat metering allocation manager device, described device for pressure measurement comprises flowmeter two and flowmeter three, described flowmeter two is connected in parallel between the head end of the head end of the female pipe of described water supply and the female pipe of described backwater, and described flowmeter three is connected in parallel between the end of the female pipe of terminal and described backwater of the female pipe of described water supply.
Described multi-functional minute family heat metering allocation manager device, described device for pressure measurement comprises the flowmeter four that is connected in parallel on described supply water female pipe or the female pipe of described backwater two ends.
Described multi-functional minute family heat metering allocation manager device, has main valve on the female pipe of described water supply, described main valve flowmeter one in parallel, described flowmeter one series connection valve one, described main valve is connected with described master controller respectively with described flowmeter one.
Described multi-functional minute family heat metering allocation manager device carries out the method for heat metering, and this method comprises the steps:
(1) calibration process: open-minded by master controller control main valve, progressively all open the smart valve on each user's pipe, the flow of total hotlist when measuring smart valve on each user's pipe respectively and opening, the flow of flowmeter two, flowmeter three is calculated the resistance of female pipe under different flow in view of the above; Close total valve then, valve one is opened, the smart valve on each user's pipe is open-minded separately successively, records the flow of flowmeter one, flowmeter two, flowmeter three respectively, calculates the resistance of each user's pipe in view of the above;
(2) measuring process: will be as the foundation of measuring period with the data that calibration process records; Because the user regulates by regulating switch time, user's hydraulic parameters is constant relatively, so can use the calculation of parameter user's who records in the demarcation flow; As the user of least significant end, be 1t/h at the flow of timing signal, flowmeter three corresponding flow are 0.5t/h; And measure is that the reading of flowmeter three is 0.6t/h, and the flow that then can infer user's pipe when its smart valve standard-sized sheet is 1 * 0.6/0.5=1.2t/h, or the like.
(3) checking procedure: open the smart valve that a part has user's pipeline of nominal data, and close the smart valve of other user's pipeline, data that record with native system and the contrast of the data of timing signal, whether see reasonable, if rationally illustrate that then data are credible, otherwise the explanation doubtful data should be demarcated again.For example, the flow of flowmeter two is 1t/h when timing signal user pipeline 1-3 all opens, and the flow of at this moment total hotlist is 5t/h; The flow of flowmeter two is 0.8t/h during verification, and the flow of total hotlist is 4t/h, then by verification; If surpass allowable error, illustrate that then certain link has problem, should demarcate again.Especially close the smart valve on whole user's pipes or close main valve and valve one can detection system have or not leakage: do not reveal if having, the flow of total hotlist should be zero.
Beneficial effect:
1. the present invention has only used several measuring instruments, just realized the flow measurement at complete group of hot user (tens families are to tens families), significantly reduced the quantity that needs the flowmeter of maintenance, space hold, once investment, later maintenance work all will significantly reduce, because the flow of each household has been arranged, the household metering that realize heat is just than being easier to.
2. the present invention only measures flow (temperature sensor and the integrator of user entry are not installed) system will greatly be simplified.This moment, system provided each user's flow and time data, can be used as the foundation of sharing, and is obviously than more approaching reality of simple time, simpler, also just more economical.In addition, one of hypothesis of make-and-break time area-method is that every square meter area flow at each family is identical, and difficult realization has had flow measurement and time measurement in the practical operation, can carry out Equivalent Conversion.For example, the flow of standard is 2.5Kg/m2, if actual flow is higher by 5% than standard, if share by the time area-method, its equivalent ON time suitably should be increased, and for example adds 5%, or the like.
3. the present invention can be provided with a different maximum conduction ratio to different valves, and is less according to the nearer valve of thermal source (hot user) conduction ratio; In like manner, a bigger conduction ratio is set, thereby has realized the thermal balance of system with the relatively poor user of heat condition (cold mountain etc.).Should be noted that especially the metering of existing building heat is transformed and needed many non-technical conditions, at this moment, can use the stand-alone mode of native system, investment stage by stage is benefited stage by stage, and this is the unexistent advantage of other system.
4. the present invention has realized functions such as the hot metering in branch family, system monitoring, system debug, system management with less resource, is the hot metering management system that is particularly suitable for China's actual conditions.Another advantage is the design's a scalability, and the user can adopt suitable system (time measurement is shared, flow measurement is shared, heat metering share) according to the actual conditions of oneself, and even investment stage by stage, has realized user's interests to greatest extent.
5. the present invention is the work of being convenient to check-verifying period with the benefit that the smart valve on each user's pipe is located at the backwater side.Main valve and flowmeter were located on confession, the female pipe of backwater, to reduce the requirement of installing space in one minute.And the smart valve on each user's pipe and system's main valve branch are located at water supply, the backwater mother manages in the time of can realizing fault and turn-offs.Serious dehydration takes place in supposing the system place building, all valves can be turn-offed, and it is promptly cut that be somebody's turn to do building this moment, makes no longer dehydration of system.

The course of work:
Family heat metering allocation manager device can adopt three kinds of mode of operations in multi-functional minute of the present invention: one, system model, and control centre directly controls each smart valve, user's room temperature is regulated not responding, and can adopt this pattern when not carrying out meterage; Two, user model, this is the usual mode of operation of system, the smart valve on each user's pipe is set its time of opening of decision according to system condition and user's greenhouse, measures service time, the flow (or heat) of each user's pipe simultaneously; Three, stand-alone mode: the intelligent valve on each user's pipe is not got in touch with the external world, only accepts the setting of setting value and user's adjusting, when not having the user to regulate, is equivalent to the control valve that a numeral is set.
Embodiment 5:
Utilize described multi-functional minute family of claim 1-4 heat metering allocation manager device to carry out the method for heat metering, this method comprises the steps:
(1) calibration process: at first need to utilize the function of system to confirm not have leakage, begin then to demarcate.Open-minded by master controller control main valve, open the smart valve on each user's pipe then successively, the flow of total hotlist when measuring smart valve on each user's pipe respectively and opening, the flow of flowmeter two, flowmeter three is calculated the resistance of female pipe under different flow in view of the above; Close total valve then, valve one is opened, the smart valve on each user's pipe is open-minded separately successively, records the flow of flowmeter one, flowmeter two, flowmeter three respectively, calculates the resistance of each user's pipe in view of the above;
Record the parameter of each user's pipe;
(2) measuring process: will be as the foundation of measuring period with the data that calibration process records; After demarcation was finished, because the user regulates by regulating switch time, user's hydraulic parameters was constant relatively, so can use the calculation of parameter user's who records in the demarcation flow.Under extreme case, three pressure falls and can ignore from flowmeter two to flowmeter, and this can accomplish by the diameter that increases this segment pipe simply.Though can increase some investment, original compared with the one-tenth of each household one table, almost can ignore.Therefore, the present invention has realized being metered into the flowmeter quantum leap from make-and-break time.For example the user 1, flow at timing signal flowmeter two (perhaps flowmeter three) is 1t/h, one of them user's flow is 1.5t/h, can assert 1.5 times of flows that value is exactly this user of flowmeter two (perhaps flowmeter three) under the situation of not considering pressure drop.In fact, because flowmeter three has been arranged, we can learn that the pressure of three these segment pipes from flowmeter two to flowmeter falls, and compensate within the specific limits, make it reach our permissible accuracy.Usually, the flow of any one user's pipe meets following formula:
Gu=Gu0×G2/G20×K
Gu-user manages flow in the formula; Gu0-timing signal user manages flow; The flow of flowmeter two during G2-measurement; The flow of G20-timing signal flowmeter two; K-according to pressure and user pipe position in female pipe the definite penalty coefficient of flowmeter two to flowmeter three.
K=1-G3/G2×L/A
K-penalty coefficient in the formula; The flow of flowmeter two, flowmeter three when G2, G3-measurement; The pipeline of A-from flowmeter two to flowmeter three is long; L-the manage duct length of position from flowmeter two to the user.If flowmeter two and flowmeter three change common differential pressure measuring installation into, then need to introduce square operation, because of flow direct ratio and pressure square.
(3) checking procedure: only open the smart valve that a part has user's pipeline of nominal data, one group of adjacent user's pipeline normally, user 1-3 for example, user 5-10 or the like, data that record with native system and the contrast of the data of timing signal, whether reasonable, if rationally illustrate that then data are credible if seeing, otherwise the explanation doubtful data should be demarcated again.
Check-verifying period can be used for detection system and leak.When user's smart valve Close All, the flow of system should be pressure monitoring device two and pressure monitoring device three flow sums; And total valve and valve one be when turn-offing simultaneously, and the flow of total hotlist should be zero.Open user's intelligent valve separately in turn, can find out is that leakage has taken place that user.
Three above-mentioned cycles are not simple circulations, but measuring period and check-verifying period need circulation to carry out, and part verification work also can be finished in measuring period.Once demarcating the effective time in cycle can set, can the setting-up time condition, conditions such as user data deviation condition, thermal technology's data variation condition trigger the demarcation cycle and begin once more.
The present invention has solved a plurality of users' flow measurement problem with the flowmeter of minority, if want to record each user's heat, it is just passable only need to increase supply and return water temperature measurement and integrator etc. as common calorimeter, different is that the flow that common flowmeter provides is continuous, and native system provides is interim: when smart valve was closed, flow was zero; Flow was provided by system when smart valve was opened.
The actual service time of valve is set by the user the deviation decision of room temperature and the actual room temperature that records.If room temperature does not reach setting value, intelligent valve increase time of opening then; Otherwise reduce and even close fully.The simplest situation is that user's indoor temperature measurement setting device is only exported a switching signal and represented whether reached the setting room temperature.Intelligent valve is a room temperature control actuator, is equivalent to flowmeter again.
Because the verification mutually of a plurality of instrument is arranged in the system, can in time pinpoint the problems, promoted the reliability of system greatly.
