Abstract
The utility model provides an energy-saving control system for building one-pipe serial connection heat supply. The system comprises temperature control valves and bypass loops which are arranged beside radiators, electric control valves arranged at the tail ends of branch pipes, temperature sensors for sensing the tail end temperatures of the branch pipes, and electronic temperature controllers for controlling the opening degree of the electric control valves according to the temperature signals sensed by the temperature sensors. The system can allow the heat consumed at the front ends of the branch pipes to be automatically transferred to the rear part of a branch pipe network after the heat consumed at the front ends of the branch pipes reaches a standard, so as to ensure the uniformity of the heat consumption. When the temperature at the tail ends of the branch pipes reach a certain standard, the electric control valves at the tail ends of the branch pipes automatically reduce the flow of the branch pipes, so as to directly reduce the heat supply quantity and the circulating water quantity, indirectly reduce the power consumption of a circulating pump and save a great deal of energy.

Current, China's town and country existing building gross area is about 40,000,000,000 square metres, and building energy consumption has accounted for nearly 30% of national total energy consumption.Along with expanding economy, expect the year two thousand twenty, China also will increase about 30,000,000,000 square metres of construction area newly, and building energy consumption will cause long-term influence to the energy resource consumption of China.China's existing building heating system mostly is the single tube train, and the characteristics of single tube train are that system is simple, easy construction, and cost is low.But the required flow of single tube train is bigger, the user can't carry out independent regulation, can only be that the user of heat opens the door by windowing and reduces indoor temperature during the cold problem in heat back before for example occurring, in addition for a certain user's heat supply, all users of this branch road must be in the heat supply state, and no matter whether other user needs heat supply, this all causes a large amount of wastes of heat supply energy consumption.Therefore, reduce existing building heat supply energy consumption whole building energy conservation is had fundamental influence.Yet, the handling characteristics of public building and with can rule making this effort become possibility again all is to use in by day working time such as most of public building, and on one's own time, for example night, the energy is wasted owing to not regulating to heating system.Generally there is 3～5 months heat supply phase in the north, well imagines the huge of energy quantity that the non-working time slatterned of this section in period.
Research for the centralized heating and energy conservation aspect at present has a lot, but be limited to boiler combustion aspect, boiler room and water pump and energy Saving technical elements more, because the system automation degree is not high, the energy-conservation effort that the terminal use carried out is difficult in the heat supply source and embodies, therefore very limited to the energy-conservation research or the transformation of system's end, at most also just the moisturizing variable frequency pump is installed, perhaps again the hydraulic equilibrium of secondary net is transformed at heat exchange station.
The utility model content
The technical problem to be solved in the present invention provides a kind of building single tube series connection heat supply energy-saving control system, and it is installed in the space heating Intranet, can control the heat supply water yield in the Intranet branch road, reaches energy-conservation purpose.
For this reason, the technical solution of the utility model is as follows:
A kind of building single tube series connection heat supply energy-saving control system, comprise: the feed pipe and the return pipe of heat exchange unit, connection heat exchange unit, and be installed in parallel many strings radiator between described feed pipe and return pipe, every string radiator is made up of the radiator of a plurality of series connection, also comprise: be installed in the water inlet of each radiator or the temperature control valve at delivery port place, described temperature control valve is regulated the output of radiator automatically according to the temperature in the building; Be arranged on the water inlet pipe of radiator and the bypass circulation between the outlet pipe, be used for after radiator reduces with heat, making hot water automatically through the bypass pipe next radiator of flowing through; Be arranged on the electric control valve of every string return branch of radiator end, be used to control the flow of hot water flux of whole arm; Be arranged on the temperature sensor of every string return branch of radiator end, be used for the temperature of perception return branch end, and control the motorized adjustment valve opening according to the temperature signal of temperature sensor perception.
Preferably, described temperature control valve is installed in the water inlet of each radiator.
What of the water yield building single tube of the present utility model series connection heat supply energy-saving control system can determine to flow into through radiator to the heat supply situation of environment according to the heat supply current, after this environment temperature reaches the design temperature requirement, heat supply water is no longer flowed through this group radiator and is flowed into next group radiator by bypass pipe, after the environment temperature of next group radiator correspondence also reaches the setting requirement, heat supply water stops again this group radiator heat supply, and flow into the 3rd group of radiator again through the other bypass pipe of this radiator, so analogize.So, the water temperature in the terminal pipeline raises gradually, after height arrives to a certain degree, can think that present heating load is excessive, can reduce the heating load to building by the way of regulating the heat supply water yield; After heating load reduces, heat loss increase along with environment, each environment need to begin heat again, like this, the water temperature in the terminal pipeline reduces gradually, when low after to a certain degree, electric control valve is opened again gradually, begin the heat supply to system, limiting case is that heating load equals the environment heat dissipation capacity, and energy efficiency is the highest.
Native system is stable and reliable for performance, investment is little, almost do not have operating cost, because therefore no any fragile parts have long service life.

The specific embodiment
Below in conjunction with accompanying drawing single tube series connection space heating energy-saving control system of the present utility model is elaborated.
As shown in the figure, system described in the utility model comprises: heat exchange unit 1, the feed pipe 2 that is connected with heat exchange unit 1, be installed in user's radiator 4 indoor and that be connected with feed pipe 2 by the water supply arm, the temperature control valve 3 of radiator 4, bypass pipe 5, water return pipeline temperature sensor 6, return pipe electric control valve 8 and the electronic temperature controller 7 of radiator 4.Temperature control valve installation 3 is installed in the water inlet of each radiator.
The course of work of native system is as follows:
The thermal source hot water that comes out from heat exchange unit 1 enters different branch road 2a, 2b through supply channel 2.In each branch road, at first enter first radiator in order, enter second radiator through the temperature control valve before second radiator in order afterwards through temperature control valve 3, and the like.Hot water in pipeline temperature behind the radiator of flowing through one by one reduces gradually, that is to say that the radiator heat-dissipation amount that the branch road initial segment is arranged is many, the room reaches the requirement temperature easily, and the arm back segment reduces owing to the heat supply coolant-temperature gage, and heat dissipation capacity also reduces, and therefore just is not easy to meet the requirements of temperature.After temperature control valve 3 is installed before the radiator, if after the temperature branch road front end room in reached the temperature that temperature-sensing valve sets, the temperature control valve can turn down automatically, enter the hot water flow of radiator with minimizing, minimizing is to the heating load in this room.Heat supply this moment water can flow into next group radiator through bypass branch road 5 automatically, make the heating load of next group radiator improve, after the room of this group radiator heat supply arrives design temperature, this group radiator thermostat valve turns down the flow that enters radiator automatically, heat supply water enters next group radiator through bypass pipe again, and the rest may be inferred.Such process just makes the terminal return water temperature of branch road raise gradually.After temperature that water return pipeline temperature sensor 6 records reaches certain value, electronic temperature controller 7 is turned the heat supply water yield of this branch road down by electric control valve 8 according to the corresponding rule of the temperature of setting-flow, to reduce heat supply consumption, also can reduce the circulating pump power consumption simultaneously.After heating load reduces, room temperature can descend gradually, after being reduced to a certain design temperature, radiator temperature control valve 3 is opened again automatically, increase is to the heat supply in room, thereby the return water temperature that causes terminal Tube Temperature Sensor to record reduces, after return water temperature is reduced to a certain setting range, electronic temperature controller 7 is controlled electric control valve 8 again and is opened, thereby increases the heat supply of output increase to branch road.Limiting case is that branch road heating load and consumption of calorie are in poised state, and temperature control valve 3 and electric control valve 8 all are in a certain aperture, for saving most heat and pump account of somebody's meritorious service attitude.
Though above to being that the heating system of medium is illustrated with hot water, native system is equally applicable to the heating system of steam or other medium.
