Description

Based on heating area and the heat metering methodology of indoor/outdoor temperature-difference and heating time
Technical field
Patent of the present invention relates to the central heating field.Can be widely used in the central heating user heating being carried out household metering based on heating area and the heat metering methodology of indoor/outdoor temperature-difference and heating time; Share foundation for user heating provides fair and reasonable heat energy, can solve the multiple problem and the contradiction that exist in the current central heating field effectively.
Background technology
In the central heating field; Need to solve the problem of how user's heating being measured and charging; According to new " heat metering technical regulation " JGJ173-2009 that puts into effect of current country, the heat metering method mainly is divided into following four kinds: radiator heat distributes meter method, family with calorimeter method, flow temperature method and make-and-break time area-method.In actual application,, cause these four kinds of methods all to have obvious defects owing to exist heat transfer problem between heat supply water quality inferiority problem, family, the high hear rate problem of building top.
Radiator heat distributes the advantage of meter method: 1) the existing building transformation is convenient, needn't make the branch family into and divide the ring system horizontal; 2) it is simple to adopt vaporation-type heat to distribute the meter method to install, and price is lower.Radiator heat distributes the shortcoming of meter method: 1) restricted application can only be used for the radiator system of a definite form, and can't in floor panel heating, use; 2) correct installation site is very important, especially the low-temperature heat supply system; 3) medial temperature of heating radiator must guarantee within limits, otherwise the error of bringing is bigger; 4) can't effectively solve heat transfer problem between the family, the high hear rate problem of building top; 5) specialized company's unified management and service, its cost of investment and overhead cost are all higher.
The advantage of user's calorimeter method: metering is accurate, and reading is directly perceived, can be used as the direct foundation of heating charge.The shortcoming of user's calorimeter method: 1) current calorimeter is difficult to satisfy the present situation of China's heat supply water quality inferiority, and the initial outlay height or the failure rate height of family table all are subject matter; 2) according to " measurement Law ", the calorimeter of settling accounts needs periodic calibrating, the large-scale difficulty that a lot of practical operations are arranged of using; 3) inapplicable single tube cascade system, and the indoor employing of Chinese most of northern area existing building is the single tube series system, it is very big to cause indoor pipe network to change thus; 4) can't effectively solve heat transfer problem between the family, the high hear rate problem of building top.
The advantage of flow temperature method: had both the partial function of calorimeter, temperature difference metering user that can be through measure supplying backwater use heat.The shortcoming of flow temperature method: 1) essence of this method metering be still the actual heat consumption of user, can't solve still that wall conducts heat between the family, the problem more than building end, the top layer heat dissipation; 2) because the T-valve of regulating belongs to manual equipment, can not automatically adjust to heating load, thereby can't effectively utilize indoor free heat, energy-saving effect is relatively poor; 3) change when system's shock resistance, all users' flow needs test again, and management maintenance is complicated; 4) workload of flow measurement is big, and the user is difficult to generally accept, and makes that the practical operation difficulty is bigger.
The advantage of make-and-break time area-method: 1) develop, be convenient to the user and accept by the traditional area charge of pressing of China; 2) high reliability, low installation cost; 3) realized that metering and temperature control are integrated.The shortcoming of make-and-break time area-method: 1) can't solve the problem that unmatched problem of radiator rating and user change big radiator rating without authorization; 2) simple time measurement is insensitive to the seasonal variety of environment temperature, causes the actual consumption in the identical heating time possibly have very big-difference; 3) should not realize locellus metering and temperature control; 4) should not in floor panel heating, use; 5) can't effectively solve heat transfer problem between the family, the high hear rate problem of building top.
Summary of the invention
Patent of the present invention provide a kind of new ideas based on heating area and the heat metering methodology of indoor/outdoor temperature-difference and heating time (hereinafter to be referred as " AKT method "); It is according to People's Republic of China's industry standard " heat metering technical regulation " JGJ173-2009; From heating system is the visual angle of the actual utility that provided of heating user, the solution with top standard that works out.The AKT method can be applicable to the central heating field carries out heat metering to user's heating and shares use, also can be applied to central air conditioner user heat and refrigeration is measured and is shared use.
The AKT method is on the basis of further investigation China's heat supply present situation and residenter house characteristic; Introduced the notion of " effectively energy consumption "; Adopted thermal-arrest can consume metering and the controller of temperature control one and disposed outdoor temperature sensor with indoor temperature transmitter and regulate heating power arm flow or control the electric control valve of heating power arm break-make; Through reduction because the heat energy loss that objective factor caused or gain and the effective thermal energy consumption of protrusion user under different outdoor environment temperatures and indoor heating temperature such as the heat conduction between building structure and the different user room and heat radiations; Metering user room pairing energy consumption of each sampling time section under real-time outdoor environment temperature and indoor heating temperature then; At last share a building heat that calorimeter measured according to " the area * temperature difference * time " of user heating; As basic foundation, thereby found the effective way of multiple contradiction between balance central heating and the individual heating to user charge.
The AKT method is by HVAC measurement controller, indoor temperature transmitter (S i), outdoor temperature sensor (S o), electric control valve (M i), composition such as communication device, monitoring host computer.According to different demands, the temperature control in user room can be selected following dual mode with adjusting: 1) mode of temperature control and adjusting is unified in all rooms, and this mode need be installed one group of S i/ M i(be S 1/ M 1) and one and S 1Antithesis temperature sensor S 2, S 1With S 2Be installed separately in two of the user the most frequently used rooms M 1Being installed in heating system registers one's residence on the water inlet pipe (or return pipe) of arm; 2) mode of each room difference temperature control and adjusting, this mode generally can select to install 2 to N group S according to user's room quantity i/ M i(1≤i≤N), S iBe installed in each room of user M iBe installed in S iThe water inlet pipe (or return pipe) of the cooling system arm in room, place; Different according to communication framework mode, can select the mode of wireless remote communication or IC-card communication usually for use.
1. key concept definition
Effective energy consumption: heating period is because the average thermal energy consumption in the user room that indoor/outdoor temperature-difference caused is called effective energy consumption.
The antithesis temperature sensor: unify in the technical scheme of temperature control and adjusting in all rooms, need be antithesis temperature sensor (S 1/ S 2) be installed separately in two the most frequently used rooms of user, and antithesis temperature sensor (S 1/ S 2) detected a pair of indoor temperature is through the indoor heating temperature of revised higher value as this user.Adopt the antithesis temperature sensor not only can measure user's indoor heating temperature exactly, the measurement deviation and the energy dissipation that can also prevent the user that certain room, indoor point for measuring temperature place is leaked informaton for a long time and causes well.
2.AKT the measuring principle of method
The mean kinetic energy Ek of a large amount of molecules of the gas that is made up of monoatomic molecules and the relation of its temperature T are derived as through statistical thermodynamic theory:
E(-)k＝3/2kT
Wherein k=1.391 * 10-23J/K is Boltzmann (Boltzmann) constant.
Conversion and law of conservation according to above formula and energy; A small amount of loss (also there are certain positive correlation in this loss and indoor/outdoor temperature-difference) and secondary thermal source in the transportation of heat before registering one's residence of ignoring are wanted factor to the minor impact grade of heating system inner room temperature; Average indoor/outdoor temperature-difference is directly proportional in the real-time energy expenditure rate that can infer the heat supply of heating management department and the heating system, can be expressed as with formula:
W＝§AΔK
Wherein, § is the mean heat transfer coefficient of external wall in the heating system, and unit is W/K.m 2A is effective external surface area of building in the heating system, and unit is m 2Δ K is an indoor/outdoor temperature-difference average in the heating system, and unit is K.To a heating system, § and A are specific in heating season.
For the room of unique user independently; A small amount of loss (also there is certain positive correlation in this loss and indoor/outdoor temperature-difference) and the secondary thermal source of heat in the WT-MSR front end is registered one's residence arm of ignoring wanted factor to the minor impact grade of room temperature, and the power consumption rate in the time of in fact can be expressed as with formula:
W i＝§ iA iΔK
Wherein, § iBe the mean heat transfer coefficient of user room exterior wall area, unit is W/K.m 2A iBe the exterior wall area in user room, unit is m 2Δ K is the indoor/outdoor temperature-difference in user room, and unit is K.For the room of unique user independently, § iAnd A iBe certain, promptly under the prerequisite of leaking informaton of not windowing, the specific consumption in user room is directly proportional with indoor/outdoor temperature-difference.
For different user in the building, the mean heat transfer coefficient § in its room iCan be because factor such as heat conduction between building structure and the user room and heat radiation and difference is very big.In same one deck heating user in building, § iBig more user's energy expenditure rate is big more, but its indoor temperature is low more on the contrary.Therefore because the heat energy loss that objective factor such as heat conduction and heat radiation causes between building structure and the different user room is should only not collect the charges to the user that heat waste is arranged.In practical operation, this part method of being taked to share out equally by the expense of the heat energy loss that objective factor caused is more feasible.
No matter be with the exterior wall area in user room or with the floor area of building in user room as its heating area (this can according to the relevant regulations of government department or by heating management department and user's consult to decide); For the room of unique user independently, its energy expenditure rate is directly proportional with indoor/outdoor temperature-difference.Can draw thus as drawing a conclusion: for Lou Dongzhong any one user that is mutually related; The indoor heating temperature that under certain outdoor environment temperature, is reached is exactly that heating system is " actual utility " that it provided, and the pairing thermal energy consumption of this actual utility is exactly its effective thermal energy consumption i.e. " an effectively energy consumption ".Therefore, effective energy expenditure rate of user is directly proportional with indoor/outdoor temperature-difference---the measuring principle of AKT method that Here it is.
3.AKT the metering formula of method
The AKT method is effective energy consumption of metering user heating well, but it can not be as the direct foundation of settling accounts between Thermal Corp and the user.According to heat metering technical regulation, the mode that adopts the AKT method to need a supporting employing building calorimeter to share is settled accounts user's heating.
When (1) temperature control is unified in all rooms of user, the metering formula of AKT
Effective energy consumption formula of user heating: E i=1/3600 * § iA i∫ Δ K (t) dt
Wherein, E is effective consumption of heat energy (available energy consumption) of user heating in the sampling period, and unit is Wh; § iFor the general power of user i room place building heat transfer under the unit indoor/outdoor temperature-difference share out equally that the floor area of building of this building obtains heat transfer coefficient, unit is W/K.m 2A iBe the floor area of building in user room, unit is m 2Δ K (t) for t constantly to the detected indoor temperature of Ai definite indoor heating temperature and the detected outdoor environment temperature of S0 poor through revising after, unit is K; T is the time interval of sampling, and unit is s.
If the heat supply total amount of a building calorimeter metering is Q in heat supply season, the user of n household metering is arranged in the building, then the heat that should share of user i is:
q i = Q × E i / Σ i = 1 n E i
Effective energy consumption formula according to user heating can be released:
Figure BSA00000522576700042
= Q × [ A i ∫ ΔK ( t ) dt ÷ Σ i = 1 n A i ∫ ΔK ( t ) dt ]
(2) during user room single-room temperature control, the metering formula of AKT
If the heat supply total amount of a building calorimeter metering is Q in heat supply season, the user of n household metering is arranged in the building, user i has j room, and the area in each room is A Ij, then the heat that should share of user i is:
q i = Q × Σ j E ij / Σ i = 1 n Σ j E ij
Effective energy consumption formula according to user heating can be released:
Figure BSA00000522576700045
= Q × [ Σ j A ij ∫ ΔK ( t ) dt ÷ Σ i = 1 n Σ j A ij ∫ ΔK ( t ) dt ]
4. the heating metering period confirms
Adopt the AKT method that household metering is carried out in central heating, can consider in principle whether the electric control valve of controlling service pipe is on off operating mode, therefore can effectively solve the measurement problem that conducts heat between the family.But consider when the user stays out in order to reduce the value of its indoor temperature, therefore the mode of leaking informaton of may taking to window need take effective measures to solve how to reduce the problem that the user windows and leaks informaton to reduce indoor/outdoor temperature-difference.
When the user adopts the electric control valve with flow regulating function to carry out temperature control, can be the heating period of whole heat supply season as the user.But window and leak informaton in order to reduce the user, need be in heating period user's motor-operated control valve the period of buttoned-up status, give certain metering discount d, 0≤d≤1.
When the user adopts the electric control valve with on-off function to carry out temperature control, can be the heating period of whole heat supply season as the user.But window and leak informaton in order to reduce the user, can be in heating period user's motor-operated control valve the period of closed condition, give certain metering discount d, 0≤d≤1.When d=0, the AKT method is exactly the make-and-break time area-method that has temperature difference weight.
Through the above measure determined heating metering period, both guaranteed heat conduction between the family is measured and reduced the purpose that the user windows and leaks informaton, again can encourage users actively energy-conservation.
5. the mensuration of indoor heating temperature
Because in the process of installation, the temperature of interior sensor point for measuring temperature often can not reflect user's average room temperature, therefore be necessary the detected temperature of each sensor is measured.Consider the curvilinear characteristic of indoor temperature change generated in case; Adopt simple fixing temperature modified value not go out the Changing Pattern of indoor temperature by accurate response, so be necessary to adopt comparatively accurate linear interpolation method or other dynamic correction method that the detected temperatures of indoor temperature transmitter is revised.
If R iBe S iThe mensuration temperature of sensor, t iBe S iThe observed temperature of sensor, t oBe the observed temperature of outdoor temperature sensor, h is the modified value under the reference temperature H (general desirable H=18 ℃).At temperature-fall period, work as t iLevel off to outdoor temperature t oThe time, indoor temperature can trend towards balance.In sum, can be to S iDetected temperature correction is following:
R i＝t i+[(t i-t o)/(H-t o)]×h
Therefore, for the sensor S in any room iAs long as, confirmed the h value that it is corresponding, measure temperature R just can calculate it i
When temperature control is unified in all rooms of user, need to adopt the method for antithesis sensor that user's indoor temperature is measured, at this moment the medial temperature R=MAX (R in all rooms of user 1, R 2); When user's room single-room temperature control, the medial temperature of user room j is R j
Need be noted that the detected temperatures of indoor temperature transmitter will be as much as possible near average indoor temperature, thereby reduce the correction of detected temperatures to greatest extent.
6. the calculating of non-heating user's intermittent heating expense
Owing to there are the objective factors such as heat conduction and heat radiation between the different user room; The non-heating user of Lou Dongzhong has also obtained the heat energy that heating system provided indirectly; Especially be positioned at the non-heating user of a centre, building, all its indoor temperature also can be quite high during heating as its user up and down.Therefore when Energy Saving Control and metering are carried out in each door type heating, be necessary to study the expense metering method to non-heating user's intermittent heating, effective solution of this problem can significantly reduce the contradiction dispute between domestic heating and the heating.Because non-heating user also possibly take the auxiliary heating in local room of other heater means, directly measures the secondhand heat energy of non-heating user and unrealistic.
The AKT method also provides the technical scheme of non-heating user's intermittent heating expense in a kind of calculating building with universality.In order to simplify computation process, can take following technical finesse: 1) non-heating user and with its non-heating user who faces mutually between the party wall wall area not as effective heat transfer area; 2) think that the temperature in the heating user room is a uniformity; 3) think that the inside surface in user room has the identical coefficient of overall heat transmission.
Then non-heating user's intermittent heating expense computing formula is F=dk ∑ f iS i, wherein: d is the discount rate that user's intermittent heating expense is calculated, k is the coefficient of overall heat transmission (can obtain through the method for simulation test or field measurement) of shared wall, f iBe the heating cost that the unit internal surface area in certain the heating user room adjacent with non-heating user is shared out equally, S in heating season iFor non-heating user and with its certain heating user who faces mutually between party wall wall area (being effective heat transfer area).
7. the beneficial effect that uses the AKT method that heat metering is shared
(1) had both the advantage of high-precision advantage of calorimeter and make-and-break time area-method high reliability;
(2) user who has avoided in the process of using the make-and-break time area-method, possibly running into increases the worry of heating installation capacity without authorization;
(3) efficiently solve the measurement problem that conducts heat between many measurement problems of building top heat dissipation and family;
(4) user side integrated metering and function of temperature control, realized the integrated and intelligent of metering and temperature control;
(5) temperature control and the metering that single household is whole be can realize, temperature control and metering also can be realized single house and single room;
(6) be not only applicable to the metering and the temperature control of radiator heating, be applicable to the metering and the temperature control of floor panel heating yet.
The AKT method is to heating user's beneficial effect: the metering to each door type heating user thermal energy consumption can reflect effective energy consumption that it is actual more exactly; The user can be provided with the indoor heating temperature as required at times, allows the user to carry out the switch control of daily automatic or manual, can practice thrift user's heating cost to greatest extent; Reliability of products is strong and the installation and maintenance expense is all lower.Under the metering method guiding of fair and just, along with user's energy-conservation theory and improving constantly of energy-conservation social responsibility, the AKT method will be received more desirable effect.
Beneficial effect to heat supply power company: practiced thrift mass energy consumption; Saved handling cost; Properly settled the Three Difficult Issues (conducting problem between water quality inferiority problem, architectural top high energy consumption problem, family) that run in the heat supplying process, effectively balance the various contradictions between central heating and the individual heating.

8.AKT method and standard make-and-break time area-method
If T iBe indoor temperature transmitter S iThe mensuration temperature, T oBe outdoor temperature sensor S oDetected temperatures, the indoor heating temperature of heating period standard is made as T r, the outdoor environment temperature of heating period standard is made as T s, the on average the highest outdoor environment temperature of heating period is made as T Max, the average minimum outdoor environment temperature of heating period is made as T Min, q iBe " T i-T o" to " T r-T s" conversion the time equivalent, T MaxCorresponding T rUnder the time equivalent be q Max, T MinCorresponding T rUnder the time equivalent be q Min
The definition of " outdoor environment temperature of standard ": when the heat supply condition was identical, the heating time of unit source under this temperature equaled unit source at T MaxUnder heating time with at T MinUnder the mean value of heating time.The definition of " the indoor heating temperature of standard ": according to relevant regulations, the intermediate value of user indoor temperature under normal heating situation that heating management department must guarantee.
When outdoor environment temperature equals T sAnd the indoor heating temperature equals T rThe time, definition: q s=1, the actual heating time of expression unit source this moment equals its " standard time ".
∵ q iWith (T i-T o) be directly proportional the heating time of unit source and (T i-T o) be inversely proportional to
The heating time and the q of ∴ unit source be inversely proportional to=＞1/q s=(1/q Max+ 1/q Min)/2
By q i=(T i-T o)/(T r-T s)
＝＞1/(T r-T s)＝[1/(T r-T max)+1/(T r-T min)]/2
＝＞T s＝T r-[2(T r-T max)(T r-T min)]/[2T r-(T max+T min)]
＝＞q i＝(T i-T o)[2T r-(T max+T min)]/[2(T r-T max)(T r-T min)]
If k=is [2T r-(T Max+ T Min)]/[2 (T r-T Max) (T r-T Min)]
Q then i=k (T i-T o)
In sum, when the AKT method adopted the make-and-break time metering user heating of the motor-operated control valve that is installed in the arm of registering one's residence, it can equivalence be converted into " standard make-and-break time area-method ".Therefore, " standard make-and-break time area-method " is equivalent to the make-and-break time area-method that has the indoor/outdoor temperature-difference weight.
