Description

Measure method and the heat metering distribution system thereof of the hot user's heating load of vertical sigle-pipe concurrent-flow

Technical field

The present invention relates to a kind of warm metering distribution system, be specifically related to a kind of method and heat metering distribution system thereof that measures the hot user's heating load of vertical sigle-pipe concurrent-flow.

Background technology

China is building big country, reaches 164.88 hundred million m to urban housing, 2005 end of the years whole nations floor area of building ², cities and towns covil construction area 147.44 hundred million m wherein ²Residential floor area 107.69 hundred million m ², public building area 39.75 hundred million m ²For keeping indoor temperature, the annual a large amount of energy consumption of consumption that needs.Be to reduce building energy consumption, China since last century the eighties issue and implement the energy Saving Design of Residential Buildings standard.The building energy conservation of China is at first from the design of the new building in northern central heating area.Severe cold and cold district were implemented the design standards of heating and energy saving rate 50% in 1996 in the design standards of tentative newly-built residential architecture heating and energy saving rate 30% in 1986, and implemented the design standards of heating and energy saving rate 65% in 2010.Central China Xia Redong cryogenic region energy Saving Design of Residential Buildings standard was implemented from calendar year 2001, and fractional energy savings is 50%; South Residential Buildings In Hot Summer And Warm Winter energy-saving design standard was implemented from 2003, and fractional energy savings is 50%.

China executes design standard for energy efficiency of buildings at new building at present, but still also has a large amount of existing buildings not according to the energy-saving design index formation.There is data to show, at 107.69 hundred million existing m ²Only having in the residential architecture about 10% is building according to the energy-saving design index formation.In order to reduce the heating energy consumption of northern area Heating Residential Buildings, country begins to advance the reducing energy consumption of existing building the Eleventh Five-Year Plan period, and the building of implementing reducing energy consumption is given award on the fund.During " 12 ", country further enlarges the reducing energy consumption scale of northern area Heating Residential Buildings; Requirement is finished heat metering and the reducing energy consumption that the north is possessed the old dwelling house of the value transformed substantially before the year two thousand twenty.To " the 12 " end of term, each provinces and regions, city will finish at least the locality and possess heat metering and more than 35% of reducing energy consumption area of transforming the old dwelling house that is worth.

The heating heat metering of northern China building started from from eighties of last century eighties.Country in new building, enforces the metering of heating heat.The newly-designed building of China, indoor heating system all is single household horizontal system, and the heat measuring method of application mainly contains: temperature-area method, radiator heat distribute meter method, flow temperature method, family with calorimeter method, make-and-break time area-method, based on the flow temperature method of room temperature etc.The heating system of the existing building of the northern area of China mostly is greatly vertical sigle-pipe concurrent-flow.Aforesaid these heat measuring methods can satisfy the hot measuring requirement of new building, but scarcely are suitable for transforming for the heat metering of existing building.

1. temperature-area method

Volume heating heating index and room height that temperature-area method is based on each household in the same buildings are constants, the residing outdoor conditions in each family is identical in the buildings, the heat that each user consumes is relevant with indoor temperature and floor area of building, therefore can by the indoor temperature in metering room, measure the heat of using of each household.The method has solved the measurement problem that conducts heat between the family of China's apartment class dwelling house existence; Solve the heat that each diverse location room energy consumption difference is brought in the buildings and taken unfair problem.Accomplished the user in the same solitary building, if heating area is identical, within the identical time, identical temperature should be paid identical hot expense.From measuring principle, temperature-area method can be used for the heat metering of existing building and transform.But since the method need to be in each room of hot user the set temperature sensor, and each sensor need to couple together with wire, this is for fitting-up craze user, although be difficult to support that the installation of indoor temperature transmitter can solve the problem of sensor backguy with radio transmitting method, but exist the equipment cost height, the problem that the wireless transmission battery life is short.

2. radiator heat distributes the meter method

Radiator heat distribution meter method is the method that the heat dissipation capacity of utilization measurement user heating radiator is measured heat, mainly contains two kinds of vaporation-type and electronic type allocation tables.On principle, the method can be used for the heat metering of existing building and transform.But because the most installation of heat radiator cover of the hot user of China; The user changes arbitrarily the kind of heating radiator and the variety classes curtain is set in buildings according to the hobby of oneself, thereby so that the existing building heating system of China can not satisfy the service condition that radiator heat distributes the meter method to require.Advance the equivalent heat distribution list method that occurred in several years, can only be used for the heat metering of single household horizontal heating system.

3. make-and-break time area-method

The make-and-break time area-method is under the identical condition of the initial indoor temperature at each family, comes the metering heating amount by heating time and the area that measures each household.It is larger that the method measurement accuracy is affected by medial temperature, and hot user's self-changeable heating radiator installs heating radiator privately additional, will add causus metering result's uncertainty.It must be single household horizontal system that the method requires the heating system of each household.

4. family calorimeter method

The family is comprised of flow sensor, pairing temperature sensor and counter with calorimeter, carries out heat Calculation according to formula (1).According to the flow sensor form, calorimeter mainly contains two kinds of ultrasonic calorimeter and mechanical heat meters.Ultrasonic calorimeter, price comparison is high.Mechanical heat meter, low price, but because China's hot-water heating system water quality inferiority causes mechanical heat meter to stop up in a large number, can't work.It must be single household horizontal system that the method requires the heating system of each household, transforms if the method is used for the metering of existing building heat, after then needing vertical sigle-pipe concurrent-flow is transformed into single household horizontal system, just can use.This improvement cost is high, and it is serious to disturb residents.

Q _i＝G _iC(t _gi-t _hi) (1)

In the formula

Q _iThe heating load that represents i the hot user of heating;

G _iThe circular flow that represents i the hot user of heating;

C represents specific heat of water;

t _Gi, t _HiExpression enters i heating user's supply water temperature, return water temperature.

5. flow temperature method

The flow temperature method is to share total amount of heat according to hot user's flow and supply backwater temperature difference.The present domestic three kinds of forms that mainly contain:

Flow and the supply backwater temperature difference of form one, measurement buildings gross heat input, each household carry out heat distribution according to formula (2).

$Q_i=Q_0\frac{G_i(t_{\mathrm{gi}}-t_{\mathrm{hi}})}{\mathrm{\Σ}{G}_i(t_{\mathrm{gi}}-t_{\mathrm{hi}})}---\left(2\right)$

In the formula

G _iThe circular flow that represents i the hot user of heating, kg/h;

Q ₀Expression buildings gross heat input.

t _Gi, t _HiExpression enters i heating user's supply water temperature, return water temperature, ℃.

The flow of form two, definition each household and the ratio of a building total flow are the flow proportional coefficient

Then formula 2 becomes

$Q_i=Q_0\frac{{\mathrm{\α}}_i(t_{\mathrm{gi}}-t_{\mathrm{hi}})}{\mathrm{\Σ}{\mathrm{\α}}_i(t_{\mathrm{gi}}-t_{\mathrm{hi}})}---\left(3\right)$

The flow proportional number of supposing hot user is constant, then measures the supply backwater temperature difference of buildings gross heat input, each household, carries out heat distribution according to formula 3.

Form three, hot user's flow proportional number is fixed, measured the supply backwater temperature difference of buildings gross heat input, each household, carry out heat distribution according to formula (4).The method is called the flow temperature method of benchmark room temperature.

$Q_i=Q_0\frac{{\mathrm{\φ}}_i(t_{\mathrm{gi}}-t_{\mathrm{hi}})F_i}{\mathrm{\Σ}{\mathrm{\φ}}_i(t_{\mathrm{gi}}-t_{\mathrm{hi}})F_i}---\left(4\right)$

In the formula

φ _iRepresent i the heating user and constant heating system and room temperature relative;

F _iThe user's area that represents i heating user, m ²

Form one adopts mechanical flow table measuring flow, can be used for the metering of existing building heat and transform.But owing to can't avoid China's hot-water heating system water quality inferiority, the mechanical flow table stops up, weares and teares and the vent plug problem, makes its application limited.

The form two hot users' of hypothesis flow proportional number is that constant is non-existent in the heat measuring system of reality, implement the system of heat metering, because hot user regulates, a certain family system stops heating or because the custom system maintenance, to cause the flow amortization ratio of each household in the metering system to change, the heat that brings thus the user to measure changes.The method can be used for the metering of existing building heat to be transformed, but the resultant error of metering is larger.

The flow temperature method of benchmark room temperature has solved the flow proportional number and has not been the problem of constant, can realize the user in the same solitary building, and heating area is identical, and within the identical time, identical temperature is paid the heat metering target of identical heat expense.But only can be used for single household horizontal system, can not be used for vertical sigle-pipe concurrent-flow.

Although China's heat measuring method kind is a lot, present situation is: the method that has can not be used for vertical sigle-pipe concurrent-flow; The method that has is available from principle, but often exists current conditions not satisfy the pacing items of heat measuring method requirement, the aesthetic property that heat metering retrofit work amount is large, affect user's indoor heating system, has the serious problem that disturbs residents.The existing building heat metering of China is transformed, and is badly in need of the new heat measuring method of invention, to satisfy the hot metering demand of existing building.
