Description

Technical Field

[0001] This utility model relates to the field of fresh air system technology, specifically a suspended heat recovery fresh air device. Background Technology

[0002] As an air purification device, the core function of a fresh air system is to drive indoor air circulation. It relies on mechanical power to bring fresh outdoor air into the room after sterilization, disinfection, and filtration, while expelling stale indoor air, ensuring that the indoor air environment is always fresh and clean.

[0003] Ceiling-mounted fresh air systems have significant advantages due to their unique installation method: they are usually installed inside the ceiling, which does not take up indoor floor and wall space, making the indoor space appear more open; and they can achieve ventilation and air exchange in all rooms of the house, meeting the air purification needs of large-area houses, and are therefore widely favored.

[0004] However, existing ceiling-mounted fresh air units have obvious drawbacks in use: because the interface direction of the fresh air unit is fixed and cannot be changed, its installation location is greatly restricted, and a special installation space must be reserved around it, making it difficult to make reasonable use of space. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a suspended heat recovery fresh air device, which can solve the problems of limited installation position and low space utilization caused by the fixed interface direction of the suspended fresh air unit, making the installation of the fresh air unit more flexible and making reasonable use of the surrounding space.

[0006] The technical solution of this utility model is to provide a suspended heat recovery fresh air device with the following structure: a housing, one end of which is provided with an outdoor air inlet and an outdoor air outlet, and the other end of which is provided with an indoor air supply outlet and an indoor return air outlet; the outdoor air inlet is connected to an outdoor air inlet connector, one end of which is rotatably connected inside the outdoor air inlet; the outdoor air outlet is connected to an outdoor air exhaust connector, one end of which is rotatably connected inside the outdoor air exhaust outlet; the indoor air supply outlet is connected to an indoor air supply connector, one end of which is rotatably connected inside the indoor air supply outlet; and the indoor return air outlet is connected to an indoor return air connector, one end of which is rotatably connected inside the indoor return air outlet.

[0007] With the above structure, the suspended heat recovery fresh air device of this utility model has the following advantages compared with the prior art:

[0008] Because the suspended heat recovery fresh air device of this utility model allows for flexible adjustment of the direction of each interface by rotating and connecting the outdoor air inlet connector, outdoor air outlet connector, indoor air supply connector, and indoor return air connector to the corresponding air outlets, it effectively breaks the installation position limitation caused by the fixed interface direction. It eliminates the need to reserve special installation space around the device, greatly improves the rationality of space utilization, and makes the installation of the device more flexible.
