The utility model solves the problems of the technologies described above adopted technical scheme: a kind of air-conditioning Optimal Control System, comprise temperature sensing device, PLC control system, air-conditioning, air-conditioning is provided with return air inlet, it is characterized in that being also provided with fresh wind tube, new air-valve, new fan valve executor, air returning valve, air returning valve actuator, air-intaking box, described temperature sensing device comprises outdoor temperature sensor, indoor temperature transmitter, on the return air inlet of air-conditioning, air-intaking box is installed, air-intaking box and return air inlet for air-conditioner UNICOM, air-intaking box is provided with air-intaking box return air inlet, air-intaking box air inlet, air-intaking box air inlet is attached to outdoor by fresh wind tube, air-intaking box return air inlet installs back air-valve, fresh wind tube is installed new air-valve, air returning valve actuator is installed on air returning valve, on new air-valve, new fan valve executor is installed, PLC control system and outdoor temperature sensor, new fan valve executor, indoor temperature transmitter, air returning valve actuator all connects.
Air-intaking box described in the utility model is hexahedron air-intaking box.
On the utility model fresh wind tube, Rainproof louver window is installed.
The utlity model has simple for structurely, diverse in function, both can utilize indoor return air, can utilize again outdoor new wind to reach the features such as cooling-down effect.
Accompanying drawing explanation
Fig. 1 is the application structure schematic diagram of the utility model embodiment.
Fig. 2 is that schematic diagram is looked on a left side of Fig. 1.
Fig. 3 is the schematic top plan view of Fig. 1.
Fig. 4 is the schematic perspective view of the utility model embodiment.
The specific embodiment
Referring to Fig. 1～Fig. 4, the utility model embodiment air-conditioning Optimal Control System, can accomplish that system is identification selection employing all-fresh air pattern automatically when environment temperature is during lower than certain value (setting in advance), simultaneously again lower than indoor temperature; When environment temperature is during higher than indoor temperature, also identification selection adopts full return air pattern automatically, guarantees that indoor temperature is stable, is conducive to ensure energy-conservation and safety.
For achieving the above object, the technical solution adopted in the utility model is as follows: the present embodiment application structure mainly comprises outdoor temperature sensor 1, Rainproof louver window 2, fresh wind tube 3, PLC control system 4, new air-valve 5, air-conditioning 6, new fan valve executor 7, indoor temperature transmitter 8, connects electric wire 9, air returning valve 10, air-intaking box 11, air returning valve actuator 12, ajutage 13, and PLC control system 4 is with outdoor temperature sensor 1, new fan valve executor 7, indoor temperature transmitter 8, air returning valve actuator 12 is all connected and control its work.Wherein air-conditioning 6 is prior art and is provided with return air inlet, and air-conditioning 6 is sent air-conditioner wind by ajutage 13.
The utility model on the return air inlet of air-conditioning 6 polyhedral air-intaking box 11(of fabrication and installation as hexahedron air-intaking box), air-intaking box 11Yu return air inlet for air-conditioner UNICOM, on air-intaking box 11, output an air-intaking box return air inlet 14, simultaneously on aforementioned air-intaking box 11, continue out an air-intaking box air inlet 15 and by fresh wind tube 3, be attached to outdoor, for introducing outdoor new wind.On air-intaking box return air inlet 14, install back air-valve 10, new air-valve 5 is installed on fresh wind tube 3, on air returning valve 10, new air-valve 5, fan valve executor (comprising new fan valve executor 7, air returning valve actuator 12) is all installed, fan valve executor is connected with PLC control system 4 by connecting electric wire 9.On fresh wind tube 3, Rainproof louver window 2 is installed simultaneously.At the indoor and outdoor temperature sensing device (comprising outdoor temperature sensor 1, indoor temperature transmitter 8) that is all provided with, temperature sensing device is connected with PLC control system 4, the temperature detecting by temperature sensing device, inputs PLC control system 4 by temperature signal.PLC control system 4 judges after having received the signal of indoor and outdoor temperature difference sizes, judge aperture size (proportional-type is percentage form) and the open and close speed (PID control) of new air-valve 5, air returning valve 10, finally export fill order to actuator, make two air-valve actions.
