Abstract
The utility model provides an independent branch pipe control air supply system of a fresh air replacement system. The independent branch pipe control air supply system comprises an air distributing device, speed adjusting fans, a plurality of air supply branch pipes, humidity sensors and a controller, wherein the speed adjusting fans are connected to a plurality of pipe outlets of the air distributing device, the air supply branch pipes are respectively connected with the speed adjusting fans and used for supplying fresh air to different rooms, the humidity sensors are arranged in all rooms, and the controller is connected with the humidity sensors and the speed adjusting fans. When the speed adjusting fans are started, 100% air volume air supply is achieved, and when the speed adjusting fans are stopped, the fresh air is stopped from being supplied or 20% air volume (the minimum air volume) air supply is achieved. In addition, a differential pressure sensor is arranged inside a main air supply pipe, differential pressure changes in the main air supply pipe and the air distributing device are measured, meanwhile, the air supply frequency of a total air supply machine is adjusted, and the aim of air distributing according to needs is achieved, and energy saving is facilitated.
Description
Technical field
The utility model relates to a kind of independent arm of replacing VMC and controls supply air system.
Background technology
The physical principle of displacement fresh air system for existing house: new wind is all sent from the bottom, room, and new wind is full of whole room with low-down speed with a little less than the temperature of indoor temperature.So-called low speed is exactly not produce air-flow and blowing feeling.Occupant and other Indoor Thermal load heat new wind, produce the hot plumage air-flow risen.The new general mood stream that this mode produces is directly parcel people's health, taken away waste gas and other muddy gas of stink with perspiration with it, exhalation, finally arrives the top in room, from steam vent, discharges there.In each house type, in toilet or kitchen the integrated air exhaust mouth is set, the dirty wind in other room concentrate is discharged.
Traditional displacement VMC, be mainly used in air-conditioning system, new wind is continuously to send into indoor in 24 hours, to house steward's air quantity, can be controlled, but the air output to each arm all can not be controlled according to actual service condition, new wind also continuous is sent in 24 hours in the room that makes the new wind of many unnecessary unlatchings, causes the rising of operating cost.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of independent arm of replacing VMC and controls supply air system, and it is air feed as required in real time, is beneficial to energy-conservation.
In order to solve the problems of the technologies described above, the utility model provides a kind of independent arm of replacing VMC to control supply air system, it comprises: air devider, be connected in the adjustable speed fan in a plurality of arms outlet of this air devider, with each adjustable speed fan, be connected respectively for a plurality of blowpipes of new wind being sent into respectively to chummery not, be located at the humidity sensor in each room, the controller be connected with adjustable speed fan with described humidity sensor.
As further preferred scheme, be connected with the blast main on described air devider, the blast main is provided with total pressure fan, in the blast main, is provided with for detection of the differential pressure pickup in described air devider and blast main, and this differential pressure pickup is connected with described controller.
With respect to prior art, the technique effect the utlity model has is: the independent arm of displacement VMC of the present utility model is controlled supply air system, each arm exit at air devider, built-in one small-sized adjustable speed fan arranges humidity sensor in each room, moisture signal is all sent into to the controller of air devider simultaneously, when adjustable speed fan is opened, realize 100% air quantity air-supply, when blower fan cuts out, the new wind of stop supplies or realize 20% air quantity (minimum air quantity) air-supply.Summer: when in sensing arbitrary room, relative humidity surpasses setting value (as 70%), controller is opened the blower fan on the blowpipe corresponding with this room, and this blowpipe starts to supply new wind; In sensing room, relative humidity is lower than setting value (as 55%), and controller controls this pipe blower and cuts out, the new wind of stop supplies; Winter is by above-mentioned minimum air quantity air-supply.In addition, establish differential pressure pickup in the blast main, the pressure reduction of measuring in blast main and air devider changes, and the air-supply frequency of simultaneously regulating total pressure fan, reach the purpose of air feed as required, is beneficial to energy-conservation.
The accompanying drawing explanation
In order to clearly demonstrate innovative principle of the present utility model and than the technical advantage of existing product, following two possible embodiment of limiting examples explanation by the described principle of application by means of accompanying drawing.In the drawings:
The structure chart of the independent arm control supply air system that Fig. 1 is the displacement VMC.
The specific embodiment
As Fig. 1, the independent arm of the displacement VMC of the present embodiment is controlled supply air system and is comprised: air devider 2, be connected in the adjustable speed fan 1 in a plurality of arms outlet of this air devider 2, with each adjustable speed fan 1, be connected respectively for a plurality of blowpipes of new wind being sent into respectively to chummery not, be located at the humidity sensor in each room, the controller be connected with adjustable speed fan 1 with described humidity sensor.
When adjustable speed fan 1 is opened, realize 100% air quantity air-supply, when blower fan cuts out, the new wind of stop supplies or realize 20% air quantity (minimum air quantity) air-supply.Summer: when in sensing arbitrary room, relative humidity surpasses setting value (as 70%), controller is opened the blower fan on the blowpipe corresponding with this room, and this blowpipe starts to supply new wind; In sensing room, relative humidity is lower than setting value (as 55%), and controller controls this pipe blower and cuts out, the new wind of stop supplies; Winter is by above-mentioned minimum air quantity air-supply.
Be connected with the blast main on described air devider 2, the blast main is provided with total pressure fan, in the blast main, is provided with for detection of the differential pressure pickup in described air devider and blast main, and this differential pressure pickup is connected with described controller.
The pressure reduction that described controller is measured in blast main and air devider changes, and the air-supply frequency of simultaneously regulating total pressure fan, reach the purpose of air feed as required.
The preferred single-chip microcomputer of controller.
Obviously, above-described embodiment is only for the utility model example clearly is described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And these belong to apparent variation that spirit of the present utility model extended out or change still among protection domain of the present utility model.
