Description
Technical field
The present invention relates to urban heating system and its control method are and in particular to a kind of heat exchange station secondary network hydraulic equilibrium is auxiliary
Help regulating system and control method.
Background technology
China's concentrated supply of heating in the city heat exchange station secondary network adjusts generally existing problems with present：1st, heat exchange station secondary network is
Unfavorable loop hydraulic equilibrium imbalance causes user uneven in temperature, and secondary network pump operating cycle frequency is higher, and flow is unsatisfactory for or super
Go out terminal temperature difference demand, cause energy consumption significant wastage；2nd, tradition only relies on end index circuit pressure reduction and is adjusted as reference
The mode of section, when end supply backwater pressure reduction is very little, is led to regulating effect not good by the limited error of certainty of measurement is larger；3rd, mesh
Front secondary network hydraulic equilibrium mode typically adopts the mode such as self-balancing valve, dynamic balance valve, electric control valve, system investments
Larger and increase resistance of pipe system loss and circulating pump power consumption.
In central heating system, the pressure loss of user side i.e. courtyard heating pipe network accounts for the big absolutely of the heat exchange station pressure loss
Part, the lift that water circulating pump provides for whole distributing system, consumed by all parts in cyclic process and pipeline.For example have
Heat exchange station secondary network flow meansigma methodss be 3kg/ (m2H) more than, and some heat exchange stations 2.5 kg/ (m2H) just can stably transport
OK, or even the heat exchange station 2 kg/ (m that has2H) just can run.Relation N/N according to power and flow1=G³/ G1If, flow
2.5 can be reduced to from 3, then circulation pump power can be reduced to original 55%, this namely this control method energy-conservation mistake to be illustrated
Journey.
The operation of big flow can alleviate the imbalance of system thermal drying in any case, but big flow is run and be may require that
Big water pump, big energy consumption,, the adjustability reducing system, front end user excess heat supply, end is used in the investment that also can increase equipment
The not hot situation in family.Realize drop flow run, first have to solve be how effectively complete the regulation of courtyard heating pipe network
Journey, initial adjustment is mainly dependence and changes pipeline resistance value to realize, and generally adjusting us is not know that impedance is how many on earth,
When can only see flow, and seeing Flow-rate adjustment, if the hydraulic stability of pipe network is bad, traditional method will adjust several times ability
Substantially leveling.If flow is reduced to 2.5 kg/ (m2h) by us, the serious mistake of heat exchange station thermal drying having will certainly be led to
Adjust, front end user excess heat supply, that terminal temperature difference flow is unsatisfactory for room temperature is low.The basic reason of so heating system thermal misadjustment
Be hydraulic misadjustment be assignment of traffic uneven caused by, therefore eliminating most effective, the most economical method of system thermal misadjustment should be to being
The uniformity that system carries out flow is adjusted.
According to P=SG, drag losses equal to impedance be multiplied by flow square, when courtyard heating pipe network is adjusted, least favorable end
In the case of user's valve wide open, impedance S is constant, so drag losses P and flow G's square is directly proportional；When change courtyard heating pipe network
In any valve aperture, user behind becomes consistent and waits than imbalance.
