Central air conditioner system control appliance
Technical field
The utility model relates to a kind of central air conditioner system control appliance.
Background technology
The application of central air-conditioning in city is increasingly extensive, is a big power consumer, and its subject matter is, cannot regulate air output according to the concrete condition of chummery not, and still air-supply as usual when unmanned or room temperature is low, has wasted a lot of energy.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of central air conditioner system control appliance.
For realizing this technical purpose, the scheme that the utility model adopts is:
Central air conditioner system control appliance, comprises central air-conditioning, and central air-conditioning connects the air outlet in a plurality of rooms by many air supply ducts; On every air supply duct, be equipped with volume control damper, volume control damper is connected with valve positioner, and valve positioner is located at the air outlet place in room, is also connected with temperature sensor and pyroelectric infrared sensor; Valve positioner receives the signal from temperature sensor and pyroelectric infrared sensor, when the signal transmitting when temperature sensor or pyroelectric infrared sensor reaches predetermined value, valve positioner sends signal to volume control damper, controls by the new wind flow of volume control damper.
The beneficial effects of the utility model are, can air output be controlled according to the concrete condition in each room, have greatly saved the energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model system.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1, central air conditioner system control appliance, comprises central air-conditioning 1, and central air-conditioning connects the air outlet 7 in a plurality of rooms by many air supply ducts 2; On every air supply duct, be equipped with volume control damper 3, volume control damper is connected with valve positioner 4, and valve positioner is located at the air outlet place in room, is also connected with temperature sensor 5 and pyroelectric infrared sensor 6; Valve positioner receives the signal from temperature sensor and pyroelectric infrared sensor, when the signal transmitting when temperature sensor or pyroelectric infrared sensor reaches predetermined value, valve positioner sends signal to volume control damper, controls by the new wind flow of volume control damper.
The utility model in use, when the temperature signal of temperature sensor collection is greater than predetermined value, control volume control damper and increase the new wind flow of passing through, to reduce indoor temperature by valve positioner; When temperature is less than predetermined value, reduce new wind flow, with the indoor temperature that raises.Whether pyroelectric infrared sensor has a people for detection of indoor, and when signal shows nobody, valve positioner is controlled the new wind flow that volume control damper reduces to pass through, with the indoor temperature that raises; When signal shows people, increase new wind flow, to reduce indoor temperature.
The above; it is only preferred embodiment of the present utility model; not in order to limit the utility model, any trickle modification that every foundation technical spirit of the present utility model is done above embodiment, be equal to and replace and improve, within all should being included in the protection domain of technical solutions of the utility model.
