Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a multi-channel bypass component. Background Technology

[0002] Traditional centralized air conditioning systems mostly involve indoor units drawing in air through return air vents mounted in the ceiling. This air mixes with fresh air drawn in from the outside, undergoes heat exchange in a total heat exchanger, and is then distributed to various rooms through supply air vents. This single-channel structure works fine for heating or cooling needs in winter and summer. However, for seasons when heating / cooling is not required, if users only need air circulation for ventilation, the single-channel structure is insufficient. This is because in a single-channel system, the return air must undergo heat exchange in a total heat exchanger before being reintroduced into the room through the supply air vents, rather than being directly returned to the room. Utility Model Content

[0003] The purpose of this invention is to overcome the deficiencies in the prior art and provide a multi-channel bypass component. By adding a bypass vent, the return air and supply air channels can be directly connected through the bypass vent when heat exchange is not required, effectively reducing the overall energy consumption of the equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-channel bypass component, including a housing, an air inlet on a first side of the housing, an air outlet on a second side opposite to the first side, and a bypass ventilation opening on a third side next to the first side. The air inlet is connected to an indoor return air duct, the air outlet is connected to a total heat exchange air duct, and the bypass ventilation opening is connected to an indoor supply air duct. A first air valve is embedded in the air outlet, and a second air valve is embedded in the bypass ventilation opening. An electrical control component is fixed to the side wall of the housing and electrically connected to the first and second air valves.

[0005] Preferably, the housing includes a frame and a foam panel covering the outside of the frame.

[0006] Preferably, multiple sets of lifting lugs are installed on the frame of the box.

[0007] Preferably, the lifting lug is L-shaped, with its vertical surface fixed to the frame and its horizontal end provided with a lifting slot. The lifting slot extends at both ends and is vertically bent with retaining edges, and the retaining edges at both ends are bent in opposite directions.

[0008] Preferably, the first air valve is installed on the housing inside the air outlet, while a first connecting flange is provided on the outside of the air outlet.

[0009] Preferably, the second air valve is installed on the housing inside the side ventilation opening, while a second connecting flange is provided on the outside of the side ventilation opening.

[0010] Compared with the prior art, the multi-channel bypass component disclosed in this utility model has the following beneficial effects:

[0011] The multi-channel structure allows for the opening of a bypass channel by closing the first air valve and opening the second air valve when heat exchange is not required. This multi-channel structure can effectively reduce overall energy consumption and facilitates switching.

[0012] The lifting lug structure installed on the side wall of the frame can meet the lifting needs on both the front and back sides. Attached Figure Description

[0015] Figure 3 This is a structural diagram of the lifting lug in an embodiment of this utility model. Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The multi-channel bypass component disclosed in this utility model is installed in the air duct of the indoor unit, and its structure is as follows: Figures 1-2 As shown, the device includes a housing 1. An air inlet 2 is located on the first side of the housing, an air outlet 3 is located on the second side opposite the first side, and a side ventilation vent 4 is located on the third side next to the first side. The air inlet is connected to the indoor return air duct, the air outlet is connected to the total heat exchange duct of the indoor unit, and the side ventilation vent is directly connected to the indoor supply air duct. A first air valve 5 is embedded in the air outlet, and a second air valve 6 is embedded in the side ventilation vent. An electrical control component 7 is fixed to the side wall of the housing and electrically connected to the first and second air valves. The electrical control component controls the opening and closing of the first or second air valve. When the first air valve is open, the second air valve is closed. At this time, the return air supplied by the air inlet enters the total heat exchange duct for heat exchange and is then sent out through the indoor supply air duct. When the second air valve is open, the first air valve is closed. At this time, the return air supplied by the air inlet is directly sent to the indoor supply air duct through the side ventilation duct and then sent out.

[0018] Specifically, the enclosure includes a rectangular frame 11 and a foam panel 12 covering and installed on the outside of the frame. To facilitate hoisting during installation, multiple sets of lifting lugs 8 are installed on the frame of the enclosure, and the lifting lug structure is as follows: Figure 3 As shown, the whole is L-shaped. The vertical surface 81 is used for installation with the frame, while the horizontal surface 82 is used for hoisting. The end of the horizontal surface is provided with a hoisting slot 83. At the same time, the two ends of the hoisting slot extend and bend to form a retaining edge 84. The retaining edges at both ends are set with one forward and one reverse bend. During hoisting, the hook is placed in the hoisting slot and the retaining edge is used to block the side and prevent it from falling off during hoisting. The forward and reverse bending mechanism can meet the hoisting requirements of the lifting lug in either the forward or reverse direction.

[0019] The first air valve is an electrically controlled air valve, which is installed on the housing inside the air outlet. At the same time, a first connecting flange 9 is provided on the outside of the air outlet, which is connected to the total heat exchange air duct. The second air valve is also an electrically controlled air valve, which is installed on the housing inside the side ventilation opening. A second connecting flange 10 is provided on the outside of the side ventilation opening, which is connected to the indoor air supply duct.

[0020] The multi-channel bypass component disclosed in this utility model can realize arbitrary switching of air ducts and meet the requirements of reducing energy consumption under the need for circulating ventilation.

[0021] Finally, it should be noted that the above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
