Description

Technical Field

[0001] This utility model relates to the field of fresh air technology, specifically a prefabricated fresh air chamber. Background Technology

[0002] Conventional fresh air chambers utilize masonry structures. Each air conditioning unit has its own fresh air section, drawing fresh air through openings in the exterior wall. Typically, near the exterior windows of the air conditioning room, several small functional rooms are partitioned off, containing sections for fresh air filtration, fresh air fans, and fresh air preheating. During construction, after the equipment is installed, it is separated using corrugated steel sheets or lightweight walls; alternatively, block walls are constructed simultaneously with the main structure. However, discrepancies may arise between the actual purchased equipment and the original design specifications, leading to rework. Furthermore, if equipment damage occurs during later use, the outer perimeter walls must be demolished, a cumbersome process that increases the workload for staff. Utility Model Content

[0003] The purpose of this invention is to provide a prefabricated fresh air chamber, which can at least solve some of the defects in the existing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated fresh air chamber, comprising a bottom plate, a top plate, and side plates forming a frame structure, wherein a filter wall, a preheating wall, and an air duct wall are sequentially and spaced apart within the frame structure, and the filter wall, the preheating wall, and the air duct wall are all detachably installed on the frame structure; the filter wall, the preheating wall, and the air duct wall are all prefabricated components.

[0005] Furthermore, one of the side panels is an air intake louver wall.

[0006] Furthermore, the air inlet louver wall is vertically arranged, and the air inlet louver wall has several blades with adjustable pitch angles.

[0007] Furthermore, at least one of the filter wall, the preheating wall, and the air duct wall is snapped into the frame structure.

[0008] Furthermore, the filter wall includes a wall body and a roller shutter disposed on the wall body.

Detailed Implementation

[0028] 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 scope of protection of the present utility model.

[0029] Please see Figures 1 to 9This utility model embodiment provides a prefabricated fresh air chamber, including a base plate 1, a top plate 2, and side plates 3 forming a frame structure. Filter walls 4, preheating walls 5, and air duct walls 6 are sequentially spaced within the frame structure. All three walls are detachably mounted on the frame structure. All components are prefabricated. In this embodiment, prefabricated components are used for on-site assembly, resulting in minimal wet work. The fresh air chamber can be assembled in a single room. During later maintenance, only the individual modules need to be replaced if repairs are required. Specifically, all components are prefabricated, such as the base plate 1, top plate 2, side plates 3, filter wall 4, preheating wall 5, air duct wall 6, and air inlet louver wall 7. The installation method uses a detachable connection for assembly, which improves assembly efficiency during initial installation and allows for replacement of necessary parts during later maintenance, saving costs and greatly improving operational efficiency. The walls used are no longer simply for partitioning, but rather function as nodes in the fresh air chamber equipment. For example, filter wall 4, although a wall, does not only serve a partitioning function but also filters; preheating wall 5, although also a wall, also serves a preheating function; similarly, air duct wall 6 and air inlet louver wall 7, although prefabricated wall structures, function as air outlets and inlets, thus not merely serving as partitioning walls. During installation, the base plate 1, top plate 2, and side plates 3 form a frame structure, such as a square frame, and then the required prefabricated walls are sequentially installed within this frame. Of course, the assembly order can be adjusted. As shown in this embodiment, the base plate 1 can be installed first, and then the air inlet louver wall 7, filter wall 4, preheating plate wall and air duct wall 6 can be installed on the base plate 1 in sequence. Then the top plate 2 and other side plates 3 can be installed according to the process.

[0030] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9One of the side panels is an air inlet louver wall 7. Preferably, the air inlet louver wall 7 is vertically arranged and has several blades 70 with adjustable pitch angles. In this embodiment, one side panel can be a functional air inlet louver wall 7. The function of the air inlet louver wall 7 is to supply air into the frame structure, and then the air passes through the filter wall 4, the preheating wall 5, and the air duct wall 6 in sequence before being discharged. The filter wall 4 filters the air, the preheating wall 5 heats the air, and the air duct wall 6 facilitates the discharge of fresh air. The blades of the air inlet louver wall 7 are adjustable to control the amount of air entering. When adjacent blades are arranged in parallel, the air intake is at its maximum. The adjustment of the blades can be done manually or automatically by a motor in conjunction with a controller. That is, a common logic controller is used to control the rotation of the motor, and then the blades are driven to rotate through racks, pinions, or other transmission methods, thereby adjusting the gap between adjacent blades.

[0031] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 At least one of the filter wall 4, the preheating wall 5, and the duct wall 6 is snapped into the frame structure. In this embodiment, the filter wall 4, the preheating wall 5, and the duct wall 6 can be snapped into the frame structure. Snapping is one method of detachable connection; of course, other connection methods can also be used, and this embodiment does not limit this. The specific form of snapping can be a protrusion inserted into a groove. For example, protrusions can be designed on the wall, and grooves can be designed on the bottom plate 1 and the top plate 2 for the protrusions to snap into. Of course, it can also be the other way around; the design of the bottom plate 1 and the top plate 2 does not need to be consistent, and the choice of which has a protrusion and which has a groove can be made according to needs. The connection between the wall and the side plate 3 can also be snapped into, such as by setting a fixing post on the side of the wall, and the fixing post being fixedly installed in the fixing hole of the side plate 3. There are many ways to fix and install, and this embodiment does not limit this.

[0032] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 The filter wall 4 includes a wall body and a roller shutter 40 mounted on the wall body. In this embodiment, the roller shutter 40 is installed on the wall body, which means that the existing roller shutter filter is integrated with the wall body to realize the prefabricated filter wall 4. Preferably, the filter wall 4 has rollers 41 on both the upper and lower sides, and the roller shutter 40 is wound around the rollers 41 and rolled up by the rollers 41. Several tensioning shafts 42 are also provided in the height direction of the wall body to support the roller shutter 40. The rollers are permanent magnet electric rollers, and the rollers are composed of high-performance hard magnetic materials to form a composite magnetic system. They have the characteristics of high magnetic field strength, large depth, simple structure, convenient use, no maintenance, no power consumption, and no demagnetization after years of use. Polyester fiber filter cloth is used between the rollers, which solves the problem of difficult cleaning and replacement of traditional fresh air static pressure box filters and makes the equipment quieter.

[0033] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 The preheating wall 5 includes a wall body and heating pipes 50 disposed on the wall body. In this embodiment, the heating pipes 50 are installed on the wall body, that is, the existing heating pipes 50 are integrated and installed together with the wall body to realize the prefabricated preheating wall 5. Preferably, a far-infrared quartz heating tube is used in the middle of the wall body, which has high thermal efficiency, long service life and is easy to replace.

[0034] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 The duct wall 6 includes a wall body and a plurality of through holes 60 formed in the wall body, at least one of the through holes 60 being equipped with a fan. Preferably, the fan is a bladeless fan. In this embodiment, similarly, the fan can also be designed on the wall body to form the duct wall 6. Designing multiple through holes allows for multiple fans to be installed, improving exhaust efficiency. The bladeless fan used utilizes fluid dynamics engineering technology, using a high-efficiency brushless motor to increase airflow by tens of times compared to traditional axial flow fans. During later maintenance, a specific module can be replaced, reducing later maintenance costs.

[0035] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 One of the side panels 3 has an opening, which is sealed with a door panel. In this embodiment, the opening on the side panel 3 is equivalent to creating a door in the panel, facilitating staff entry into the fresh air chamber.

[0036] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 The frame structure is a rectangular frame, with the filter wall 4, preheating wall 5, and duct wall 6 all vertically arranged and spaced parallel to each other within the frame. In this embodiment, besides using a rectangular frame, other shapes can be designed as needed, such as columnar fresh air chambers, spherical fresh air chambers, etc., simply by changing the shape of the components used; this embodiment does not impose any limitations on this.

[0037] As an optimized embodiment of this utility model, temperature and humidity sensors are installed inside the room. The sensors are connected to the air inlet louver wall 7, the filter wall 4, the preheating wall 5, and the air duct wall 6 respectively to achieve linkage control.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
