Description
Technical field
The invention belongs to building heat supplying system control technology field.Be primarily aimed under traditional heat-supplying mode, especially to mixed net thermal field institutes such as colleges and universities, enterprises and institutions, integrated mills, because different hot users is hot because of not using in the different periods, but situation about can't regulate, and the inefficient present situation of the heat supply of the big little temperature difference of flow, and a kind of time sharing great temperature difference heat supply energy conserving system that proposes.By the concrete point of application is provided, the huge energy saving space with under the present operation conditions is converted into considerable energy saving reality.Comprise that hardware configuration and software module combine system.
Background technology
Prior art is treated and is mixed the various different buildings with thermal characteristics of putting in same heat supply zone, 24 hours continuous heat supplies of unified implementation, and this just causes having at times wastes a large amount of heat energy with the building of thermal characteristics in the hot period of non-usefulness; And the big flow in the heat supplying process and the little temperature difference (about 10 degree) and return water temperature are higher; The heating power that is difficult to avoid is unbalance, and the formation near-thermal is far cold.
Summary of the invention
Purpose of the present invention just provides the time sharing great temperature difference heat supply energy-saving control system of a kind of solution " the timesharing district heating is regulated and the little temperature difference and big flow " problem, tries to achieve the purpose that realizes eliminating and improving a series of relevant issues.With the huge energy saving space under the present operation conditions,, be converted into considerable energy saving reality by the concrete point of application.
Technical solution of the present invention is by heating system hardware is transformed, mainly to comprise electric switching valve, outdoor temperature sensor, supply and return water temperature sensor and intelligent controller etc.; Software and method are built in the intelligent controller.Have at a large amount of groups of building and hot user and to use thermal property at times, propose that time-sharing heating is to cut the waste as required, big temperature difference transmission ﹠ distribution are to promote efficient, and weather compensates antifreeze safety, and intelligence is switched method such as in good time comfortable and carried out heat regulation.
Hardware configuration of the present invention is hot user, and the thermal region porch of promptly single building or identical function is provided with electric switching valve, and monitoring outdoor temperature Tw and supply and return water temperature Tg, Th are provided with intelligent controller IC nearby.Intelligentized function is mainly calculated by software analysis and is realized.
Comprise in conjunction with its composition shown in Figure 1: thermal source circulating pump 1, in hot user 3 porch electric switching valve 2 is set, supply and return water temperature sensor 4,5 and ambient temperature sensor 6 also comprise core cell intelligent controller 7.
Main external manifestation of the present invention is:
(1) time-sharing heating as required: this controller can place electric switching valve " opening " or "off" state automatically according to default timetable, realizes the heat supply start-stop.
(2) regulate big temperature difference transmission ﹠ distribution: even in the heat supply period, when supply backwater temperature difference during less than predetermined value, electric switching valve is placed " pass " state, the transmission ﹠ distribution process is in temporary transient standstill state.
(3) weather compensates antifreeze safety: when antifreeze operation, according to outdoor temperature, dynamically adjust return water temperature, electric switching valve is placed "open" state in good time, prevent that pipeline from freezing damage.
(4) intelligent mode switches: for guaranteeing that heat supply in time with comfortable, is transferred to the Timing Advance of heat supply period by the antifreeze period in conjunction with outdoor temperature weather Compensation Regulation.
Intelligent pang-pang control to electric switching valve: be to be starting point, taken into account security, reliability, comfortableness and the cost constraint of heat supply with energy-conservation.Why select electric switching valve for use in the system, be based on the characteristics of heat supply---be about to heat delivery to terminal, need the certain flow and the flow velocity that meet design requirement all the time.Be controlled to be the basis with simple and reliable " pang-pang ", promptly open valve and just need open foot, valve-off then directly closes dead; And it is carried out intelligence transform; By strengthening supply backwater temperature difference, promote the transmission ﹠ distribution efficiency simultaneously.
The native system operation is as follows:
At first confess hot water from thermal source by the circulating pump of VFC, hot water is released along feed pipe.Electric switching valve 2 is opened.Intelligent controller 7 is judged state of living in this moment according to default heat supply and antifreeze time.Under the heat supply period, the return water temperature T that intelligent controller 7 provides in real time according to return water temperature sensor 5
hCalculate and judge that whether it is less than the return water temperature setting value, if return water temperature T
hBe lower than setting value, illustrate that then needing to adopt heat from main pipeline network again carries out the heating agent displacement, open electric switching valve 2 this moment, switches to the outer circulation state, adopts hot the sign and put 1; If T
hBe higher than setting value, then judge residing recurrent state this moment,, then continue to keep electric switching valve 2 to open state and adopt heat, dispel the heat otherwise close electric switching valve 2 if be in the outer circulation state according to adopting the heat sign.Under the antifreeze period, intelligent controller 7 carries out the weather compensation deals according to the outdoor temperature that ambient temperature sensor 6 provides, and makes to switch lead servo-actuated outdoor temperature to guarantee meeting the requirements of the indoor temperature value in the time that requires under the varying environment temperature.During switching time of calculating, open electric switching valve 2 and switch to the heat supply running state when reaching; If do not reach switching time as yet, then continue to run on the anti-freezing and heat-insulating state, whether be lower than valve 2 on off states during required value is judged this according to return water temperature.
Beneficial effect and benefit that the present invention reached are, under the prerequisite that guarantees heat supply security, comfortableness, regulate by the subregional intelligence of timesharing, solved the different buildings of traditional heating system and mixed the thermal waste that the net heat supply is caused with hot characteristics, can save heat energy about 20～40%, economize on electricity 40～60% has very good economic benefit and environmental benefit.Energy-saving effect is obvious, and the heat supply security is good, and adaptability is strong, is applicable to newly-built system and legacy system transformation.
