The intelligent energy-saving control system is characterized by the inclusion of a main controller on the central air conditioner, a valve arranged on each heat exchange loop for adjusting the hot air flow rate, and a plurality of sub-controllers and a plurality of pyroelectric infrared probes which are arranged on the sub-air conditioners, wherein each sub-controller is connected with one pyroelectric infrared probe and one valve, and all the sub-controllers are in communication connection with the main controller. The main controller and the sub-controllers adopt microprocessors, and the sub-controllers are connected with the main controller through a distributed field bus. The utility model can realize not only flexile control of the central air conditioner to the sub-air conditioners but also energy conservation and carbon emission reduction.
Description
Technical field
The utility model belongs to electronic technology and technical field of heat exchange, relates to a kind of central air-conditioning intelligent energy-saving control system.
Background technology
Growing along with economy, the sternness of energy problem, energy-saving and emission-reduction become China and even worldwide problem.Central air-conditioning is widely used in the big city, becomes the rich and influential family of power consumption.Original central air-conditioning considers that energy-conservation factor is less, so energy consumption is also big, not only causes operating cost big, also can't realize energy-conservation target far away.
The utility model content
The purpose of this utility model is to have proposed a kind of central air-conditioning intelligent energy-saving control system, can realize the flexible control of central air-conditioning to a plurality of sub-air-conditionings, realizes energy-saving and emission-reduction.
Technical solution of the present utility model is as follows:
A kind of central air-conditioning intelligent energy-saving control system comprises central air-conditioning and a plurality of sub-air-conditioning; Central air-conditioning is connected to form a plurality of heat exchange loops by pipeline and a plurality of sub-air-conditioning; It is characterized in that, also comprise the master controller that is arranged on the central air-conditioning;
The valve that is used to regulate hot air flowrate that on each described heat exchange loop, is provided with,
And a plurality of sub-controllers and a plurality of pyroelectric infrared transducer that are arranged on a plurality of sub-air-conditionings place;
Each sub-controller links to each other with a valve with a pyroelectric infrared transducer; All sub-controller and master controllers communicate to connect.
Pyroelectric infrared transducer is mainly used in the activity whether people is arranged in the room of surveying, if long-time unmanned in the room, then control system is by pyroelectric infrared transducer, and the corresponding sub-air-conditioning of control is closed again.
As improvement, described master controller and sub-controller adopt microprocessor.
As improvement, described a plurality of sub-controllers are connected with described master controller by distributed field bus.
Advantage of the present utility model and effect:
1) saving of the realization energy: the utility model can be controlled each sub-air-conditioning flexibly according to the concrete condition in the room; If unmanned in a period of time in the room, then sub-controller can be controlled corresponding valve closing automatically, has avoided the waste of this a part of energy.
2) realize simply, cost is low: adopt microprocessor to realize the integral body control of system being mature technique as controller, and easy to implement, drop into not highly, help promotion and implementation.
3) be convenient to expansion: adopt distributed field bus communication, wiring is simple, helps the expansion of system.
Description of drawings
The structured flowchart of Fig. 1 the utility model embodiment 1.
The specific embodiment
Embodiment 1
As shown in Figure 1, whole system comprises a central air-conditioning and N sub-air-conditioning (N is corresponding with concrete room number, can be 50,100 etc., according to the actual conditions setting).Central air-conditioning is connected to form a plurality of heat exchange loops by pipeline and a plurality of sub-air-conditioning.The master controller that is provided with on central air-conditioning adopts PC; Each described heat exchange loop is provided with the valve (as valve 1 and the valve N of figure, valve is also installed near corresponding sub-air-conditioning) that is used for regulating hot air flowrate; The place is provided with a plurality of sub-controllers and a plurality of pyroelectric infrared transducer at a plurality of sub-air-conditionings; Each sub-controller and a pyroelectric infrared transducer link to each other with a valve (to be sub-controller 1 is connected with valve 1 with probe 1, and sub-controller 22 is connected with valve 2 with popping one's head in, and the like, sub-controller N is connected with valve N with the N that pops one's head in); All sub-controller and master controllers communicate to connect.Pyroelectric infrared transducer is used to survey the activity whether people is arranged in the room, if long-time unmanned in the room, then control system is by pyroelectric infrared transducer, and the corresponding sub-air-conditioning of control is closed again.
Sub-controller adopts 51 single-chip microcomputers.A plurality of sub-controllers are connected with described master controller by distributed field bus.Sub-air-conditioning place also is equipped with temperature sensor, sub-controller regular with the temperature information in the corresponding room, the master controller (PC) that information such as valve opening state and running state of air conditioner send has master controller to realize unified monitoring.Master controller also can be set the aperture of a plurality of valves according to current temperature unification by sub-controller.Thereby realize energy-saving and emission-reduction to greatest extent.
The course of work of native system is as follows: at first pyroelectric infrared transducer detects unmanned the existence in the room, if someone, then system runs well, if detect in the current room unmanned in a period of time (as half an hour), then the infrared probe signal that outputs to sub-controller changes, therefore export control signal closes corresponding valve to sub-controller, makes that the air-conditioning in the current room is in closed condition.Afterwards, sub-controller sends to master controller by distributed field bus with the information of valve closing with valve.The information that sends also comprises current sub-air-conditioning numbering, the temperature in current room and the time of valve closing etc.By master controller (PC) all rooms are carried out unified monitoring and management.
