Description

Technical Field

[0001] This utility model relates to the technical field of indoor ventilation and energy recovery equipment, and more specifically to a total heat recovery fresh air unit. Background Technology

[0002] Total heat recovery fresh air systems typically integrate air outlets, fan assemblies, partition assemblies, and a total heat exchange core in a box-like structure. They achieve simultaneous air exchange and heat exchange between indoor and outdoor air through internal ductwork. Existing similar equipment still has some common problems in structural design, assembly, and maintenance:

[0003] Firstly, when the internal space is compact, the heat exchange core often adopts frame mounting or simple support. The core relies on manual adjustment in terms of assembly positioning, circumferential fitting and limiting fixation, which can easily lead to assembly deviation or uneven fitting, resulting in reduced internal structural stability.

[0004] Secondly, when the structural boundary between the fan cavity and the heat exchange area is unclear or the separation structure is not set properly, the two air ducts are prone to form unexpected connection gaps in local locations, making the air duct isolation consistency greatly affected by assembly tolerances.

[0005] Third, if the connection structure between the inspection panel and the casing lacks clear positioning and limiting, problems such as difficulty in panel alignment, a large number of fasteners, or limited disassembly and assembly paths may occur during disassembly and assembly, thereby reducing maintenance efficiency.

[0006] Therefore, it is necessary to provide a total heat recovery fresh air unit with a clear structural layout, reliable core positioning, well-defined duct isolation boundaries, and easy disassembly and maintenance to meet the needs of engineering installation and subsequent maintenance. Utility Model Content

[0007] The purpose of this utility model is to provide a total heat recovery fresh air unit, which has a total heat exchange core arranged at an angle inside the casing and clamped and positioned by limiting components. At the same time, upper and lower partition plates and the inner wall of the casing are used to define two mutually isolated air ducts. A detachable maintenance panel and corresponding positioning and limiting structure are provided on the outside of the casing. This makes the internal structure boundary of the whole unit clear and the installation position relationship of the components clear, which facilitates assembly, disassembly and maintenance. It is suitable for the integrated installation of building fresh air ventilation system.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A total heat recovery fresh air unit includes a housing, a detachable maintenance panel is provided on the outer side of the housing, and a plurality of air vents are provided on the side of the housing.

[0010] A total heat exchange core is provided inside the housing. The total heat exchange core is inclinedly disposed inside the housing and is clamped and positioned by a first limiting member and a second limiting member.

[0011] The casing is provided with a fan cavity, and the fan cavity is provided with a supply fan and an exhaust fan;

[0012] The housing is provided with an upper partition plate and a lower partition plate. The upper partition plate and the lower partition plate, together with the inner wall of the housing, define a first air duct and a second air duct that are isolated from each other.

[0013] The first air duct and the second air duct are respectively connected to the plurality of air outlets, and the first air duct and the second air duct respectively pass through different channels of the total heat exchange core.

[0014] Furthermore, the first limiting member and the second limiting member are respectively disposed at the opposite edges of the total heat exchange core, and are respectively connected to the inner frame of the housing.

[0015] Furthermore, the outer periphery of the total heat exchange core and the inner side of the housing are respectively provided with circumferential contact surfaces, and the first limiting member and the second limiting member are located on opposite sides of the circumferential contact surfaces.

[0016] Furthermore, the fan cavity is located above the total heat exchange core, and the supply fan and the exhaust fan are arranged side by side in the fan cavity.

[0017] Furthermore, the inspection panel and the housing are detachably connected via a bottom latch.

[0018] Furthermore, the top of the housing is provided with mounting ears.

[0019] Furthermore, a control box is provided on the top of the housing, and the control box is fixedly connected to the housing.

[0020] Furthermore, the plurality of air vents includes air vents disposed on both sides of the housing, and the air vents are arranged at intervals along the height direction of the housing.

[0021] Compared with the prior art, this utility model, through the structural cooperation of the casing, maintenance panel, air outlet, total heat exchange core, limiting component, fan cavity, supply fan, exhaust fan, and upper and lower partition plates, enables the total heat exchange core to be stably arranged in an inclined posture and reliably positioned under the clamping of the limiting component. The upper and lower partition plates and the inner wall of the casing together define two mutually isolated air ducts with clear internal channel boundaries and continuous structure. At the same time, the maintenance panel adopts a detachable structure and cooperates with the bottom buckle to form an externally openable maintenance entrance. The components of the fan cavity and heat exchange area can be inspected, replaced, and cleaned through this entrance, thereby improving the assembly consistency and maintenance convenience of the whole machine while maintaining a compact structure.
