Description
Technical field
The present invention relates to metering of a kind of water heating type central heating heat and temperature control system, the specifically a kind of central heating control system and method that can realize that the user is adjustable, heat supply is controlled, the leader can manage.
Background technology
Traditional heat metering is with energy-conservation.At first, heat metering does not often almost have a direct correlation property with energy-conservation.So-called metering is energy-conservation, only through these means of metering, reminds the user to consume the numeral charge by heat, and desire is spent less, just needs to lack with heat.Through this pattern impel the consumer conscious, often be again aperture with the most original manual accent valve mode control valve, sheerly a kind of " behavior " energy saver mode.Secondly, terminal in heat supply, user oneself can not regulate or do periodically to set to regulate indoor temperature at random, can not realize independence regulation and control purpose of energy saving; On the other hand, heat supply unit can not regulate and control user's house lead in flow through telecommunication and control technology, to carry out mandatory purpose of energy saving.In addition, heat supply unit can not go further regulation and control according to the comprehensive conditions such as monitoring, regulation and control and analysis to terminal temperature difference physochlaina infudibularis numerical value, revise the operational factor of thermal substation, has realized not energy-conservation under the total system.In addition; China's central heating temperature is 18 ± 2 degrees centigrade; But because present monitoring means accuracy, reliability are low, when user's temperature was not up to standard, power & light company was difficult to monitor in real time related data; Can not in time adjust, also aggravate the imbalance between supply and demand between user and the heat supply unit heating network.
Traditional energy-conservation temperature control mode roughly has constant temperature temperature-sensing valve mode, common electric temperature control ball valve mode, paraffin electrical heating temperature control flow valve mode.Facts have proved that there are problems in these valves: at first, the valve anthority of these valves is less, and the control characteristic distortion factor of valve is bigger, when valve opening hour, flow does not reach the purpose of " adjusting " near maximum.Secondly, do not reach by difference and remove to regulate automatically this energy-saving effect of heat with the demand of hot period, intelligent low.Simultaneously, the spool water hole is thin, have the weakness of high-drag, is unfavorable for improving heating quality.As design improperly, often bring the not enough situation of available pressure.In addition, in the practical application, district system reaches 30% user, and to be in the probability of complete shut-down state very high again, considerably beyond the standard of system's water conservancy equalization point 15%.Therefore, adopting the control valve of standard-sized sheet, complete shut-down is absolute risky as far as system, and the hot meterage that is brought is inequitable, also is easy to cause supply and demand dispute and social contradications.
Summary of the invention
The present invention is directed to management and the unscientific problem of control mode that prior art exists, propose the more effective central heating control of a kind of more science system and method, make the user independently regulate and control indoor temperature according to individual demand; Heat supply unit can carry out mandatory energy-conservation to the thin user of awareness of saving energy simultaneously; In addition, heat supply unit can further carry out the correction of operational factor, thereby effectively improve heat supply efficiency, cut down the consumption of energy and heat cost according to collection and the analysis of terminal temperature difference with dsc data to the relevant device of thermal substation.
