Description
Technical field
The utility model relates to the air-conditioning system technical field, relates in particular to the plenum chamber in a kind of air conditioning duct system.
Background technology
In air-conditioning system in running, owing to must use efficient plenum chamber, so can cause occurring that the room air output is less than normal, the part filtration device structure lost efficacy or problem such as obstruction.The reason that above-mentioned situation occurs mainly is; One, the thickness of compressive plate above the efficient plenum chamber internal ramp is thinner, and rigidity is not enough, and the part distortion appears in stressed back; What two, the pressing plate of filter top adopted is engineering plastics, and engineering plastics may be out of shape when bearing bigger pressure; Three, the sealing gasket generation deformation of filter.Deform in case pressing plate distortion or sealing gasket occur, just may cause the wind passage to diminish, even inefficacy of filter part separation structure or obstruction occur.
In order to solve the problems of the technologies described above, the researcher proposes a kind of efficient plenum chamber, comprise casing and filter, described cabinet wall top is provided with fixation clip, the bottom is provided with the active type fixture, and filter is installed between fixation clip and the activity fixture, also is not provided with sealing gasket between fixation clip and filter, described active type fixture comprises the A/C of fixedlying connected with cabinet wall, and the movable pressing board that flexibly connects with A/C.
Described A/C and cabinet wall are by being welded to connect, and the A/C upper end is welded with nut; Movable pressing board is by corrosion resistant plate and be welded in stainless steel tube on the corrosion resistant plate, is provided with through hole on the corrosion resistant plate under the stainless steel tube, and described through hole directly equates with the stainless steel tube internal diameter, and the center line of through hole overlaps with the axis of stainless steel tube.Stainless steel tube inserts in the A/C, and connects by bolt between the two.Fixation clip is that stainless steel or aluminum alloy material are made.Sealing gasket is the sponge rubber pad.A/C is a stainless steel pipe.The cross section of movable pressing board is a shape.The active type fixture is connected with filter floor by corrosion resistant plate.
Filter floor is a rectangle, on the microscler direction of each bar, be respectively equipped with two active type fixtures and two fixation clips, on each bar broadside, be respectively equipped with an active type fixture and a fixation clip, all active type fixtures are connected with filter floor by corrosion resistant plate, and filter is formed supporting role.
Be equipped with screw thread on the outer wall of stainless steel tube and the A/C inwall, can realize the flexible connection of stainless steel tube and A/C by screw thread, simultaneously, above A/C, be provided with STAINLESS STEEL NUTS, screw up passes stainless steel tube from through hole, extends to the A/C top and rivets with STAINLESS STEEL NUTS, thereby stainless steel tube and A/C are fixed, make whole fixing apparatus for filter form dual connection, improved the reliability of active type fixture greatly.
Now, along with development of technology, for the all-air conditioning system, need the new air returning ratio of control, consider that noise and pressure factor need be provided with plenum chamber respectively at the air inlet place of new wind and return air, new wind and the return air branch plenum chamber that is arranged can cause two plenum chambers excessive in the general all-air conditioning system, takies the machine room space.
The utility model content
At the problems referred to above, the utility model provides a kind of saving space, integrates the plenum chamber of new wind and return air plenum chamber.
A kind of plenum chamber, it comprises first valve, second valve, control module and case body, described first valve is arranged on fresh wind port, described second valve is arranged on return air inlet, described control module electrically connects with first valve and second valve respectively, be used for controlling respectively first valve and be in different closure states with second valve, described case body is connected with return air inlet with fresh wind port respectively by pipeline, respectively from fresh wind port and return air inlet receiver gases.
Further, described control module is a single-chip microcomputer.
Further, described case body middle part is provided with insulation material.
Further, described case body exterior is provided with insulation material.
Further, described case inner body wall is provided with sound-absorbing material.
The utility model provides a kind of plenum chamber, possesses return air and new two functions of wind plenum chamber, by first valve and second valve are set, make new wind and return air not mix each other, thereby saved the installing space of plenum chamber, can reduce installation cost and time simultaneously, had very high cost performance.
Description of drawings
Fig. 1 is a kind of plenum chamber preferred embodiment of the utility model module diagram.
The specific embodiment
The utility model provides a kind of novel plenum chamber, return air and new wind plenum chamber are incorporated into together, but new wind and return air does not mix each other.Can establish valve at fresh wind port and return air inlet place, realize the purpose of the new air returning ratio of control,, be adapted to air conditioning duct system to reduce taking up room of machine room.
See also Fig. 1, it is a kind of plenum chamber preferred embodiment of the utility model module diagram.
A kind of plenum chamber comprises first valve 11, second valve 12, control module 13 and case body 14.Wherein, first valve 11 is arranged on fresh wind port, and second valve 12 is arranged on return air inlet.Control module 13 electrically connects mutually with first valve 11 and second valve 12 respectively, be used for controlling respectively the state of first valve 11 and second valve 12, particularly, control module 13 is a single-chip microcomputer, the state that control module 13 controls first valve 11 is in out, can control the state that second valve 12 is in the pass this moment; Control module 13 controls first valve 11 is in the state of pass, and can control second valve 12 and be in the state of holding this moment.Case body 14 is connected with return air inlet with fresh wind port respectively by pipeline, respectively from fresh wind port and return air inlet receiver gases, and because the control of 13 pairs first valves of control module 11, second valve 12, the new wind and the return air that make case body 14 receive do not mix each other.
The case body 14 of plenum chamber can be made by galvanized iron sheet, in case body 14 middle parts insulation material is set for preventing cold and hot bridge, and seam crossing adopts closed processes, prevents air penetration.The processing of insulation is done in case body 14 outsides of plenum chamber, or case body 14 outer setting insulation materials.Case body 14 inwalls adopt sound-absorbing material to make, or case body 14 inwalls are provided with sound-absorbing material.Case body 14 can be received in the air-conditioning unit with being flexible coupling with outside interface.
