Description
Technical field
This utility model relates to device or the systems technology field of measuring heat, particularly relates to a kind of water conservancy balance heat measuring system.
Background technology
Heat supply realizes the inexorable trend that quantifying is heating industry development, is also that market-oriented inevitable outcome move towards in heat supply, is " hot commodity " important symbol of changing.This is also paid much attention to by the Chinese government, and this work has been listed in " energy-saving and emission-reduction " important component part.Since 2007, country formulates the laws and regulations of " energy-saving and emission-reduction " just three, State Council, national each ministries and commissions promulgate the file 32 of " energy-saving and emission-reduction " in succession, 14 are just had as far as heat metering file, this suffices to show that country's attention to " energy-saving and emission-reduction " and development heat metering, in particular for the popularization of heat death theory, imperative.And government picks up from building source architectural design, it is desirable to newly build civilian residences and must possess heat death theory function.
15 province's heat supply in winter of northern China, energy consumption remains high, and collects heating cost according to area for many years always.For practicable country about building energy conservation, advance the reform associated documents spirit of heating charging system, advancing China's heating heat death theory work, the Ministry of Construction requires to want modernization overlay to become household-based heat metering at " 12 " period existing building, and new building must install heat measuring system.Various places have carried out a lot of pilot about charging per heat, but so far still without successful experience.
According to " heat metering technical regulation " (JCJ173-2009), heat metering mode is divided into two big classes: the direct metering method of heat and heat sharing metering and the indirect metering method of heat.The direct metering method of heat is the method adopting family hotlist directly to settle accounts, and each independent accounting user is measured heat.Hotlist metering total amount of heat is installed in consumer heat inlet place, heat sharing metering method Shi building (or thermal substation), the surveying record device indoor again through being arranged on house, determine the ratio accounting for total amount of heat with heat of each independent accounting user, and then calculate user share heat, it is achieved household-based heat metering.It mainly has radiator heat distribution method, flow temperature method, three kinds of modes of make-and-break time area-method.
1, family calorimeter method
The ultimate principle of family calorimeter method is: by measuring the register one's residence flow of pipeline, supply and return water temperature, directly calculates the method using heat of user.Various places had carried out a lot of pilot about charging per heat in recent years, it is mounted with the family calorimeter of various ways, it is contemplated that carrying out heat charge according to the heat of metering, it is maximum that family calorimeter method is promoted in heat supply area, fill several ten million blocks, but so far still without obtaining well-content experience.Reason is mainly: 1, owing to heat supply and water, electricity metering are different, is not simply with how much being how many.Heat is to have conductive, and a user is heat supplies up and down, even if this family turns off pipeline valve, the neighbour residence of this user indoor temperature differs less than five degree, and calorimeter reading is zero, and it is impracticable for depending merely on calorimeter meterage.2. resident family is due to the difference of position, even if area is identical, top layer keeps to the side user and middle house type, and when its temperature is identical, its heat consumption differs 2-3 times, if depending merely on table meterage, common people are unacceptable.3, because calorimeter quality problems and quality problem, according to statistics: after dress calorimeter, after 1 year can also only 30%, after 3 years can only 10%.4, heat meter belongs to measurement instrument, annual requires inspection once, and its maintenance workload is huge, costly, and annual maintenance is also impossible to.5, doing heat death theory operating mode water conservancy balance is premise, could measure under the premise of thermal balance, it does not have under the premise of water conservancy balance, do not reach the distribution according to need of user.

(1) premise adopting the method is that hot distribution meter needs to carry out coupling experiment in enforcement room with radiator, carries out the effect standard of proportionality coefficient, show that the corresponding data of radiator just can be applied, and China's radiator model is of a great variety, and it is huge that experiment detects workload.This is in China, and for the diversiform radiator in huge numbers of families, it is unthinkable for completing this task.Therefore allotter method, the difficulty promoted in China is very big, almost without popularization.
(2) resident privately more heat exchange radiator, install radiator fin additional, block the behaviors such as radiator and can affect metering effect.
(3) distribution count number is relatively big, and transcription jobs amount is big, disturbs residents.
(4) radiant floor heating system is not suitable for.
3, make-and-break time area-method
Make-and-break time area-method ultimate principle is: install heat summary table, the heat quantity consuming of metering all the building at every constructure heating entrance.With the heating system water flowing time of each household for foundation, record simultaneously and add up the turn-on time of each family on-off valve, share whole the total amount of heat built according to the accumulative turn-on time at each family in conjunction with area of heat-supply service.
In Practical Project uses, the heat metering device of make-and-break time area-method there is also many being difficult to and solves and the problem that overcomes, it is impossible to really fair and reasonable share hot expense.These problems include: carrying out break-make with electrical ball valve in 1, general make-and-break time area heat metering system, flow can not set, and the flow of general bottom is than the big 30-50% of top layer.If 2, all taking same flow with flow-control break-make device one Dong Lou equal area resident family, and resident family is due to position difference, top layer keeps to the side user and middle house type, its flow-control break-make device opening time Cha 2-3 times when its temperature is identical, if depending merely on make-and-break time charge, common people can not accept, 3, as being outwards gradually increased flow with the middle every square meter flow of house type for radix, proportionality coefficient is bad to be determined, even if determining well, common people also do not approve.4, as a periphery resident family of resident family does not move in, due to the conductivity of heat, this family is lengthened by flow-control break-make device opening time, causes overcharge.5 users can pass through overstriking indoor caliber, increase radiator area, add the means such as circulating pump, reduce service time and reduce metering heat while increase heat, impact metering justice.
