A is Areas benefiting from central heating (m
2).
Q is hour thermic load (GJ/h) under tn, t ' w condition.
Qmax is heat supply network maximum heating load (GJ/h).
In addition, for simplicity, below provide some known unit conversions:
1Kwh=3600000J=3.6*10
6J；
1KJ=0.28wh
1GJ=1*10
9J=1*10
6KJ；
1 card=4.1868J;
1 kilocalorie=1000 card=4.1868KJ;
1GJ=238900Kcal
1GJ=277.78 degree (or Kwh)=277777.78wh
Below with system, at Heating Period, operate to for the first time example and carry out calculation specifications, wherein suppose that area of heat-supply service is 1,000,000 m
2, the average design heating index is 55w/m2, and meteorological temperature is up to 0 ℃ and minimum for-10 ℃, and mean temperature is-5 ℃.
Generate the firing rate dispatch command
One, given area of heat-supply service and average design heating index, calculate per hour design heating load

2904GJ*238900Kcar/GJ=6.937*10
8Kcal
6.937*10
8Kcal/5000Kcal/Kg=139000Kg=139T
139T/83%=167.5T。
According to a hour thermic load, can calculate required boiler general power:

For example, if user's indoor temperature detected, be 16 degree, generate the design heating index 55W/m that dispatch command adopts
2can not meet user indoor temperature and reach 18 ℃, and actual heating index is 56.99W/m
2.Hence one can see that, and the actual heating index of corresponding building exceeds 1.99W/m than the design heating index
2therefore, need raising system heating load.Further, can be according to actual heating index, calculating the heating load adjustment amount is 4.33GJ, this system need to be adjusted many heat supplies of instruction 4.33GJ.
For example, if user's indoor temperature detected, be 19 degree, generate the design heating index 55W/m that dispatch command adopts
2surpass user indoor temperature and reach 18 ℃ of required heating loads, and actual heating index is 54.07W/m
2.The actual heating index of corresponding building that hence one can see that is than the low 0.93W/m of design heating index
2therefore, need minimizing system heating load.Further, can be according to actual heating index, calculating the heating load adjustment amount is 2.03GJ, this system need to be adjusted the few heat supply 2.03GJ of instruction.
