Technical field

The present invention relates to a kind of warm metering distribution system, be specifically related to a kind of method and the heat death theory distribution system thereof that measure upright single pipe series-loop system heat user heating load.

Background technology

China is building big country, reaches 164.88 hundred million m to 2005 urban housing, the whole nation at end of the year floor area of building ², wherein cities and towns covil construction area 147.44 hundred million m ²residential floor area 107.69 hundred million m ², public building area 39.75 hundred million m ².For maintaining indoor temperature, need every year to consume a large amount of energy consumptions.For reducing building energy consumption, China issues and implements energy Saving Design of Residential Buildings standard from last century the eighties.The building energy conservation of China, first from the design of the new building in northern central heating area.The design standards of severe cold and cold district tentative newly-built residential architecture heating and energy saving rate 30% in 1986, implements the design standards of heating and energy saving rate 50% for 1996, and implemented the design standards of heating and energy saving rate 65% in 2010.Central China hot-summer and cold-winter area 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 igniter was implemented from 2003, and fractional energy savings is 50%.

Current China enforces design standard for energy efficiency of buildings at new building, but still also has a large amount of existing building not build according to energy saving igniter.Data is had to show, at 107.69 hundred million existing m ²about 10% is only had to be the building of building according to energy saving igniter in residential architecture.In order to reduce the heating energy consumption of northern area Heating Residential Buildings, country, the Eleventh Five-Year Plan period, starts the reducing energy consumption advancing existing building, and gives the award in fund to the building implementing reducing energy consumption." 12 " period, country expands the reducing energy consumption scale of northern area Heating Residential Buildings further; Require before the year two thousand twenty, substantially complete the heat metering and the reducing energy consumption that the north are possessed to the old house that transformation is worth.To " the 12 " end of term, each provinces and regions, city at least will complete the heat metering of old house and more than 35% of reducing energy consumption area that locality possesses transformation value.

The phosphorus fertility of northern China building, started from from eighties of last century eighties.Country, in new building, enforces phosphorus fertility.The newly-designed building of China, indoor heating system is all 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 calorimeter method, make-and-break time area-method, flow temperature method etc. based on room temperature.The heating system of the existing building of the northern area of China, is mostly upright single pipe series-loop system.These heat measuring methods aforesaid, can meet the heat death theory requirement of new building, but the heat death theory be scarcely suitable for for existing building is transformed.

1. temperature-area method

Temperature-area method be based on the volume heating measurement of each household in same buildings and room height is constant, outdoor conditions in buildings residing for each family is identical, 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, that measures each household uses heat.This method solve the measurement problem of the housing heat-transfer that China's apartment class house exists; Solve the heat that in buildings, each diverse location room energy consumption difference is brought and take unfair problem.Accomplished the user in same solitary building, if heating area is identical, within the identical time, identical temperature should pay identical hot expense.From measuring principle, temperature-area method may be used for the heat death theory transformation of existing building.But because the method needs set temperature sensor in each room of heat user, and each sensor needs 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 bracing wire with radio transmitting method, but it is high to there is equipment cost, the problem that wireless transmission battery life is short.

2. radiator heat distributes meter method

It is utilize the heat dissipation capacity measuring user's heating radiator to measure the method for heat that radiator heat distributes meter method, mainly contains vaporation-type and electronic type allocation table two kinds.From principle, the method may be used for the heat death theory transformation of existing building.But due to the most installation of heat radiator cover of China's heat user; User, according to the hobby of oneself, changes arbitrarily the kind of heating radiator and in buildings, arranges variety classes curtain, thus makes the existing building heating system of China can not meet the service condition of radiator heat distribution meter method requirement.Enter the equivalent heat distribution list method occurred for several years, the heat death theory of single household horizontal heating system can only be used for.

3. make-and-break time area-method

Make-and-break time area-method is under the condition that the initial indoor temperature at each family is identical, carrys out metering heating amount by the heating time and area measuring each household.The accuracy of the method metering affects comparatively large by medial temperature, heat user self-changeable heating radiator, installs heating radiator additional privately, by the uncertainty of aggravation heat death theory result.The method requires that the heating system of each household must be single household horizontal system.

4. family calorimeter method

Family calorimeter is made up of flow sensor, pairing temperature sensor and counter, carries out heat Calculation according to formula (1).According to flow sensor form, calorimeter mainly contains ultrasonic calorimeter and mechanical heat meter two kinds.Ultrasonic calorimeter, price comparison is high.Mechanical heat meter, low price, but due to China's hot-water heating system water quality inferiority, cause mechanical heat meter to block in a large number, cannot normally work.The method requires that the heating system of each household must be single household horizontal system, if the method to be used for the transformation of existing building heat death theory, then, after needing upright single pipe series-loop system to be transformed into single household horizontal system, just can apply.This improvement cost is high, disturbs residents serious.

5. flow temperature method

Flow temperature method shares total amount of heat according to the flow of heat user and supply backwater temperature difference.Domesticly at present mainly contain three kinds of forms:

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

In formula

G _irepresent the circular flow of i-th heating heat user, kg/h;

Q ₀represent buildings gross heat input.

T _gi, t _hirepresent the supply water temperature, the return water temperature that enter i-th heating user, DEG C.

Form two, the definition flow of each household and the ratio of a building total flow are flow proportional coefficient then formula 2 becomes

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

Suppose that the throughput ratio number of cases of heat user is constant, then measure the supply backwater temperature difference of buildings gross heat input, each household, carry out heat distribution according to formula 3.

Form three, the throughput ratio number of cases of heat user to be fixed, measure 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 formula

φ _ithat represent i-th heating user with heating system and room temperature relative constant;

F _irepresent user's area of i-th heating user, m ².

Form one adopts mechanical flow table measuring flow, may be used for the transformation of existing building heat death theory.But owing to cannot avoid China's hot-water heating system water quality inferiority, the blocking of mechanical flow table, wearing and tearing and vent plug problem, make it apply limited.

Form two supposes that the throughput ratio number of cases of heat user be constant is non-existent in the heat measuring system of reality, implement the system of heat death theory, due to heat user regulate, a certain family system stop heating or due to custom system maintenance, to the flow amortization ratio of each household in metering system be caused to change, the heat bringing user to measure thus changes.The method can be used for the transformation of existing building heat death theory, but the resultant error of metering is larger.

The flow temperature method of benchmark room temperature, solving throughput ratio number of cases is not the problem of constant, and can realize the user in same solitary building, heating area is identical, and within the identical time, identical temperature pays the heat death theory target of identical heat expense.But only can be used for single household horizontal system, can not upright single pipe series-loop system be used for.
