In due to a series of problem so that people form a series of implacable contradictions in the consuming of comfort level and energy,
Especially in central air-conditioning supply air system, present central air conditioner system is still run under traditional mode mostly, and blower is fixed on
Full speed running under power frequency state, thus there are the following problems: if 1. using central air-conditioning supply air systems meet it is of different sizes
Between dry when room, when increasing for room load, due to cannot achieve effectively to adjustment air output, frequently result in apart from blower most
Remote end room air output is small to be unable to satisfy demand, and the operation energy consumption that will lead to central air conditioner system increases, and is for energy conservation
Unfavorable, equally, when personnel's load is reduced in the room or room of different personnel's loads, due to cannot achieve effectively to adjustment
Air output, blower still keep constant air output, cause very big energy waste；2. using the blower of frequency converter, greatly
It is open loop, manual, unlatching, closing, adjusting wind speed are both needed to manual operation, still reach to less than due power savings.
In view of this, the present invention is specifically proposed type.
Inventing type content
Aiming at the problems existing in the prior art, the purpose of type of the present invention is to provide a kind of automatic control device of central air-conditioning,
Air output can be automatically adjusted, control effect is good, and it is energy saving, service life of equipment is improved, more rationally hommization.
To achieve the goals above, a kind of automatic control device for central air-conditioning that type of the present invention provides, including air heat
Wet treatment apparatus, blower, frequency converter, controller, sensor, power supply, the air heat and wet treatment system is connected with blower, described
Blower is connected by air supply tube with the air outlet in each room, and the sensor is set in the air supply pipeline in end room, according to
Secondary to be mutually electrically connected with controller, frequency converter and blower, the frequency converter with power supply by being connected.
Preferably, the frequency converter is connected by each room control switch with power supply, and each room control switch is in parallel；
It preferably, further include winding pipe, the air outlet in each room is connected by winding pipe with blast pipe；
Preferably, shown sensor is set on the blowpipe in end room；
It preferably, further include valve, the winding pipe in each room is provided with valve, is electrically connected with each room control switch
It preferably, further include recycling branch pipe and recovery tube, the recycling branch pipe in each room is respectively communicated with recovery channel connection air heat
Wet treatment apparatus.
What type of the present invention provided, it has the following beneficial effects:
It is closed 1. the blowpipe setting pressure sensor in end room is successively connected to form with controller, frequency converter and motor
Ring control loop, when the pressure of end room blowpipe is less than pressure sensor preset value, pressure sensor is to controller
Signal occurs, controller passes through the operation of Frequency Converter Control blower, changes the revolving speed of blower, increases air output, until end room
Between the pressure of blowpipe reach pressure sensor preset value, effectively prevent frequently resulting in distance when room load increase
The farthest end room air output of blower is small to be unable to satisfy demand；Can also under conditions of meeting end room air output demand,
The preset value for adjusting pressure sensor makes blower that need not be constantly in the state of operating at full capacity, and realizes automatic adjustment air quantity, saves
The energy, the high stability of system of body.
2. frequency converter is connected by each room control switch in parallel with power supply, when the roomed switch of institute is turned off,
Frequency converter stops working, conversely, frequency converter works on, to economize on electricity.
3. air supply tube is individually conveyed to each room by blowpipe, each space air does not intersect, and ensure that room
The cleaning of interior air, to achieve the effect that refrigeration or heating, setting recycling branch pipe is individually waste heat in each room or waste cold air-flow
It recycles, forms circulation, energy consumption can be reduced.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the automatic control device for central air-conditioning that type of the present invention provides.
In figure:
1. 7. sensor of air heat treatment system 2. blower, 3. frequency converter, 4. controller, 5. control switch, 6. power supply, 8. end
9. air supply tube of room, 91. blowpipe, 10. recovery tube 11. is held to recycle branch pipe.
Specific embodiment
Type of the present invention is described further with attached drawing combined with specific embodiments below, to help understanding in type of the present invention
