Description

At any time regulate and control the heat supply network total-efficiency climate compensation system of constant temperature quasi intelligent heating by minute family

Technical field

The present invention relates to a kind ofly regulate and control the heat supply network total-efficiency climate compensation system technology of constant temperature quasi intelligent heating at any time by minute family, what especially be equipped with partial circulating short circuit pipeline that the house type circulating pump opens and closes by the temperature controller relay on the indoor confession of each user, water return pipeline combine the fully climate compensating system of the humane energy-saving potential of excavation with household metering.

Background technology

At present, the climate compensating system of known therrmodynamic system, just indoor temperature, outdoor temperature, supply water temperature and the backwater reference temperature(TR) of negatively having gathered indivedual dwelling houses by the heating power merchant controlled by these 4 temperature, realizes all users' of control supply heating load.Objectively say, keep the indoor relative constant temperature of each terminal use, the adjusting of the whole net return water temperature of " turning from a guest into a host " simply by virtue of heating system is to solve root problem (produce effects and not obvious), the boiler efficiency of each boiler room in addition, circular flow, the enclosed structure heat-insulating property of sub-district, the heat-insulating property of outside ductwork, indoor heat radiation form, outdoor temperature all changes and each user's ventilation custom at the different times of morning, noon and afternoon, door and window opens and closes at interval, all multifactor differences such as finishing property heat-insulating property is uneven, as only going operation according to the operation curve of each boiler room, adopt the unified adjustment of identical supply and return water temperature, numerous terminal uses still do not have arranging of brothers to indoor temperature with the too high or too low phenomenon that environment temperature changes, and cause the user heating quality to reduce and index is too high causes inevitable energy waste.Can predict, along with the expansion that all parts of the country progressively popularize in the household metering technology, will inevitably expand the huge heat supply of work and rest round the clock before the clearancen and draw back the energy-saving and emission-reduction space that many grades of heating gradients and the indoor no one science when stay-at-home is driven the national and even global yardstick of the humane energy-saving potentials of the energy-conservation and abundant excavation of realization science such as freezing by each user.Therefore, government should make according to consumer's oneself wish and go active work and rest heating science to join heat and transfer the policy that the whole people participate in energy-saving and emission-reduction enthusiasm, and scientific and technological circle must capture relevant technical task, the heating power operation field must be established also main in the people's idea, with the arrival in energy-saving and cost-reducing epoch significantly of meeting China's heating power industry.

Summary of the invention

The objective of the invention is: realize the household metering work of each heat supply network terminal use in conjunction with whole nation implementation, to room temperature temperature automatically controlled under capping or the bound prerequisite initiatively, fundamentally solve all therrmodynamic systems and ambient temperature compensation with this, the user's heat work and rest is combined closely and automatically to adjust the science that heat exerts oneself energy-conservation, hommization is energy-conservation, contradiction that the human rightsization are energy-conservation and complicated social problem, impel the energy-saving and emission-reduction space of the whole nation and even global yardstick to expand comprehensively, impel whole society heating power market to show that market economy rule and kownledge economy rule organically combine, the final enthusiasm of transferring whole people's energy-saving and emission-reduction realizes the unified energy-conservation and humane energy-saving potential of abundant excavation science that more combines with household measurement heat-supplying that compensates with the environment temperature fullest of heat supply network in all parts of the country.

The object of the present invention is achieved like this: comprise also that each the terminal heating user of heat supply network that now heats institute's protocols having is that all indoor heat radiations of each terminal branch family of same the temperature automatically controlled weather of net compensation heating subscriber unit are often to add the short circuit connection between the heat supply pipeline of the back segment of water return pipeline and water supply direction of the total leading portion of backwater direction to manage, pipe draws return pipe water flowing string tubing pump and non-return valve by backwater Zhi Yinguan and connects heat supply and prop up into pipe, make its in the unidirectional feeding heating tube of return pipe, go (be in the heating power terminal prop up then pick out respectively after backwater Zhi Yinguan that online heating adds before with the water return pipeline that divides the indoor heat radiation system in each terminal branch family on the household unit seals in tubing pump and non-return valve to go into pipe lead in the heat supply connection pipe of each radiator correspondence go), again at common temperature automatically controlled instrument of indoor every installation of each unit and user or the frequency conversion temperature controller that is provided with some upper limit classifications of branch and even infinite variable speed frequency conversion relay as controlling having of tubing pump or closely, in, the relay controller of Remote is in order to the stagnant heat flow of the partial circulating under the overheat condition of setting up each heat radiation system at any time.Like this, when therrmodynamic system is normally moved, each automatic temperature control instrument can be set constant temperature bound numerical value according to each user's heating consumption plan and interim wish, when indoor temperature surpasses this upper limit numerical value (can only be under situations such as outdoor environment temperature rising or reinforcement of man-made environment heat-retaining condition and the instant Heat Loss amount reduction of other minutes family, make original heat supply balance that change under " extra heat income " or " total heat loose amount reduce " situation take place, caused the phenomenon of the overheated intensification of user heating) time, give the tubing pump of this user or unit corresponding to the then inevitable relay in good time of indoor temperature controller, pump push open non-return valve draw backwater form reverse backwater stream follow through interflow or generation flow in heat supply stream collaborate again in the backwater stream along cutting out, the partial circulating of backwater flow path direction, immediately having produced in the inside of the closed water circulation system of normal heat supply network that this user dispels the heat is independently by the big change of current of " the low energy-flux densityization " of system's backwater, stream overheated in will indoor all radiators pushes forever that return pipe goes and big portion or whole stagnationizations " crowded " flowed in the heat supply of heating tube outward, the substitution radiator can only be than the slightly higher partial circulating current that but are lower than supply water temperature relatively of original return water temperature, in time causing heat radiation is that the working medium temperature reduces and significantly reduces the passive heat supply state that heat dissipation capacity and return water temperature suitably improve ...At this moment, comprise all terminal uses on each net, the subscriber unit, the originally normal total net of heat supply also has " passive heat supply " (all so automatic passive heat supplies of a lot of users in various degree, the result of influence is that the water supply mean temperature of whole heat supply network improves, inevitable " automatically " impels and heats up in the main water return tube and feed back to the total heat of the final reduction in the boiler room parameter of exerting oneself, realize apace whole heat supply network new adjustment thermodynamical equilibrium and reach total-efficiency climate compensationization science heat supply level); Because the passive heat supply of partial circulating stream, make indoor temperature begin negative the intensification, by the time negative heat up be low to moderate set temperature control following in limited time then the temperature controller relay finish and termination of pumping, remaining in inertia impact and suitable leader tape power of drawing the stream that supplies water that partial circulating points to backwater stream in indoor " heat supply-heat radiation-backwater " passage after pump stops, can be being that the working medium weight distribution returns to original or superior slightly heating operation state immediately (this just fundamentally is different from a lot of for a long time people and all repays the automatic temperature control instrument relay magnetic valve that try open circuit heat supply water pipe or short circuit confession with the heat supply current of " actively heat supply " before the partial circulating and heat radiation, the indoor temperature control weather compensatory approach of return pipe, though because this way quick stoppage indoorly just heating up and anxious heating up as for negative, but at the beginning of recovering heating, close valve, inevitable " the not recurrent state " that lose the temperature difference because of being in static on the exhausted big degree in the interior radiator, and the pressure head that successively decreases step by step of major network forced circulation just was not enough to dispel the heat static stream in being of very fast this user of promotion originally, especially should transmit going out of heat radiation system that the system head that comes can the normal operation of level before and after this user, give " short circuit " idle most in the backwater net circulation canal, and can only wait until this user dispel the heat in being on, when the following temperature difference returns under the former design weight loop parameter lentamente, indoor normally heating soon; This temperature difference recovery process lentamente often needed about 30 minutes, had caused indoor temperature to decline to a great extent already and lost the practical significance of weather compensating heating ...).Owing to be the weather compensationization that each user or subscriber unit have all been realized indoor heating, when environment temperature raises, the heat supply of whole heat supply network and backwater (or first and second confession backwater) temperature all can raise naturally, only this feedback (or through man-machine " dialogue ") is adjusted heat in time and is exerted oneself can be under automatic controlled condition on the boiler making with the fastest speed, even common coal-burning boiler also can obtain the corresponding adjustment that the stoker personnel exert oneself to boiler hot after automatically reporting to the police, make it to reach corresponding thermodynamical equilibrium and scientific energy-conservation significantly.

Owing to implemented such scheme, the present invention has realized that user's room temperature sets temperature automatically controlled under the bound prerequisite, and fundamentally having solved all therrmodynamic systems in all parts of the country with this, adjust the hommization science energy-conservation, that the human rightsization are energy-conservation, humanism is energy-conservation that boiler hot exerts oneself automatically according to the user's heat work and rest parameter under the ambient temperature compensation energy-conservation.So far, the science heating that has really realized ambient temperature compensation and the most effective saving of labor of science heat supply the tightst also the most cheap the combining that save time most---on newly-built heat supply network, only to set up the present invention (and old online at the heating power that has put into operation in the equipment cost unification that is worth by the RMB of about 100 yuan of each heating user or subscriber unit inputs, because the heat radiation architecture or the interior decoration situation of each user or subscriber unit are varied, each user or subscriber unit will relatively additionally increase by 50～200 yuan of rebuilding construction expenses that do not wait), whole input can make each user and Thermal Corp adopt at 1～3 under the energy-conservation assurance of realization 15～3%, cost-recovering in heat supply month, in the town and country in all parts of the country heating power heating engineering on more need not the existing level of Thermal Corp's integrated configuration, in order to realize this purpose of roughly the same the present invention, all comprise that the great number cost of so-called high-tech configuration drops into (such as being equipped with central processor CPU in Beijing municipalization portion of hot power system planning unification recently, divide time-division temperature function chip, the climate compensator functional chip, thermal source ICU function, the I/O input/output board, the A/D data acquisition module, monochromatic liquid crystal display, the time relay, various sensors, energy-saving controller, superfluously negative can't bear and to be worth high high-tech soft but PID computing or the like is exhaustive, hard control piece, the result still can not realize the energy-conservation purpose of science of the present invention far away ...).
