Count heat sharing value relatively low, minimum appears in March for 1095KW, its per day heat of sharing is 73KW.December, January adopt
Warm number of days is 31 days, and heat accumulative contributory value is larger, and peak appears in January for 4050KW, and per day heat of sharing is
135KW, most big 1 month moon average daily calorie value is about 1.8 times of most March in solar month of 30 days.
As shown in Figure 4, each user trembles with fear phase calorie value average for 7239KW deeply, and the 3.5 of about just cold and deeply cold phase calorie value
Times.Therefore, user's heat is carried out dividing the accuracy and fairness that are conducive to improving heat sharing at times, so as to ensure new
The science and reasonability of the hot methodology of type.
Share analysis contrast with make-and-break time area-method heat, after Heating Season terminates, gather the heat supply data of each user, foundation
Make-and-break time area-method is analyzed and processed to it and carried out with new methodology the data obtained to such as Fig. 5.
As shown in figure 5, hot methodology one is make-and-break time area-method in figure, hot methodology two is based on weather compensation
Novel hot methodology under shaping modes.Most users are in long-term on-state in whole Heating Period on-off valve, close
Total number of days of on-off valve only be about 1-2 days, and 1-201,1-501,2-301,2-302 user due to outside individual artificial situation go out
Showed it is of short duration stop warming up, wherein 1-201 is close with 1-501 user's turn-on time, and 2-301 is identical with 2-302 turn-on times.
The heat situation of sharing of selection 2-301 and 2-302 user illustrate the difference of two methods.2-301 user and 2-302
User stops warm 16 days in 2 months 18-March 5 (end cold phase) and 23-December of January 7 (deep cold phase) respectively, both heating
Total turn-on time is identical.It is equal using the calorie value apportioned by the family of method one or two, and method two is used, calorie value apportioned by the former
526KW is had more than the latter.Obviously, the thermic load of deep cold phase is much larger than thermic load first, that end is cold.The actual heat dissipation of 2-301 user
What amount should be far above stops warm 16 days 2-302 user's heat consumption in the deeply cold phase, and 2-302 user heatings heat is taken should be relatively fewer.It is right
Than two methods, identical the paid heat of number takes identical when 2-301 user and 2-302 user are by heating in method one, and this is right
2-302 user is inequitable, and method two considers the influence for having arrived different periods thermal difference, with more fairness.
User is within first, last cold and deep cold identical turn-on time phase, and heat consumption has very big difference, make-and-break time face
Area method carries out heat distribution due to accumulating turn-on time and heating area according to user, it is impossible to reflect this difference, and Novel hot
Methodology is gathered and shared in real time according to total amount of heat situation of change, fully takes into account the shadow of different periods heating load difference
Ring, it is clear that more fair, reasonable.
In summary, heat distribution is carried out using the disconnected time and area method of new break-make, each user distributes heat and user
Heat consumption is that outdoor temperature change is basically identical, solves same time, different periods heat sharing variability issues, its heat
Fairness in distribution, rationally, meet " equal area user, under conditions of same comfortable degree, pay it is identical heat expense " principle.With Handan
Two unit users in the demonstration quarter of Dancheng are research object, the data after collection Practical Project test, by comparative analysis
Draw, using the Novel hot amortization techniques based on weather compensation, each user distributes heat and user's calorific requirement i.e. outdoor temperature
Change is basically identical, solves same time, and different periods heat sharing variability issues, its heat distribution is fair, reasonable, symbol
Close the principle of " equal area user under conditions of same comfortable degree, pays identical heat expense ".Verify new system compared with original system more
With fairness, reasonability, a thinking is provided for the improvement of make-and-break time area-method.
The present invention proposes the Novel hot pool schemes based on weather compensation, on this basis, develops phase therewith
The supporting make-and-break time area-method heat metering device based on weather compensation.During the regulation of the heat death theory technical basis weather compensation
Section determines the apportioned mode of heat, changes disposable apportioned mode and shares for fixed cycle is real-time accumulated.By the way that whole Heating Period is drawn
It is divided into several and shares the cycle, dynamically distributes are implemented to total amount of heat, make heat sharing more reasonable in terms of algorithm, metering is relatively public
It is flat just, solve for the hot variability issues of different periods same time caused by, return water temperature influence.Engineering practice table
Bright, using the Novel hot amortization techniques based on weather compensation, each user distributes heat and become with user's calorific requirement i.e. outdoor temperature
Change is basically identical, solves same time, and different periods heat sharing variability issues, its heat distribution is fair, reasonable, meets
The principle of " equal area user under conditions of same comfortable degree, pays identical heat expense ".
The present invention considers influence of the on-off valve regulation of user to gross heat input, proposes in original (heat metering code) point
On-off valve regulation is carried out if any user in the cycle of stand, the scheme shared of a heat is carried out, to ensure total heat supply in day part
Amount does not change.Hot apportioned mode is periodically shares, and the accumulative summation of end of the season entirely will be divided into several points by Heating Period
In the stand cycle, in heating end of the season, by the accumulative summation of the calorie value for being distributed each cycle, obtain the total allocation heat of each user
Value.According to the Time segments division under weather compensation shaping modes, share the cycle using a period as one, when the cycle is corresponding
After section terminates, share the total amount of heat of a building period.In the meantime when some user turns off or on, when gathering one time
Between share a heat because can all have influence on the hydraulic regime of pipe network by the open and close of user, it is necessary to consider changes in flow rate
Influence to heat sharing, realizes to adopt and divides.On-off type heat measuring system based on weather compensation is to be regulated to core with room temperature
The heart, the heating turn-on time according to each user combines the heating area, " Lou Dong that fixed cycle is shared building total amount of heat in real time
Metering, is shared by family " heat death theory and control technique product.The system is controlled by the room temperature being placed in each household typical room
Device is instructed to on-off controller sending action, and the disconnected regulations of logical are carried out to the flow rate of heat medium for flowing into heat user heating system, and control is sent
Enter the heating load in room, so as to realize that room temperature regulates and controls.During the regulation of the heat sharing pattern foundation weather compensation of heat measuring system
Section is determined, after each end cycle, and heat of the heating area to building total heat scale is combined according to the heating turn-on time at each family
Amount is shared in real time, and in heating end of the season by the accumulative summation of calorie value apportioned by each cycle, that determines each family always uses heat
And the hot expense that should be paid.
Make-and-break time area method heat metering system based on weather compensation is to current make-and-break time area-method heat death theory system
That unites is further perfect, and the system integrates regulation and metering, had both realized the regulation respectively to each family indoor temperature, and had given again
Go out relatively reasonable heat sharing method.The core technology of the system is the regulation period of foundation weather compensation to determine heat sharing
Pattern and the apportioned mode that divides is adopted, share by using fixed cycle is real-time accumulated, solve with duration different periods heat differential
