Description

Technical Field

[0001] This utility model relates to the field of small fresh air unit technology, specifically a small condensing heat recovery fresh air unit. Background Technology

[0002] A small-scale condensing heat recovery fresh air system is a highly efficient and energy-saving air handling device. It utilizes condensing heat recovery technology to recover and reuse the heat energy from the exhaust air, heating the fresh air and achieving efficient energy use. This type of fresh air system typically includes components such as a heat exchanger, fan, compressor, condenser, and evaporator. During operation, fresh air exchanges heat with the exhaust air in the heat exchanger, recovering the heat energy from the indoor air. Then, it is compressed to increase its temperature and pressure, entering the condenser to exchange heat with the refrigerant, ultimately heating the fresh air. The refrigerant releases heat in the evaporator, cooling the fresh air and completing the cycle.

[0003] Small-scale condensing heat recovery fresh air systems can be customized to meet diverse building and environmental needs. They can be installed indoors or outdoors and are suitable for various environments, including residential, office, and commercial spaces. The advantages of these systems include high energy efficiency, energy saving, reduced energy consumption, and improved indoor air quality. Furthermore, modern fresh air system designs also consider factors such as noise control, ease of installation, and maintenance.

[0004] According to the patent application for a small air purifier (authorization publication number: CN218296112U), "This utility model discloses a small air purifier, including a base plate at the bottom of the air purifier body, a fixing component at the front end of the air purifier body, and a movable component inside the air purifier body. The movable component includes a rectangular plate located on the inner wall of the air purifier body. This utility model utilizes a fixing block so that when maintenance personnel need to remove the filter plate, they only need to push the movable block to drive the movable plate to push the semi-circular plate into the limiting component. The two limiting components of the limiting frame plate are then manually separated from the fixing block. The operator can then pull the frame plate downwards while supporting it with one hand from below the air purifier body. When the frame plate is pulled out downwards, the filter plate fitted inside the frame plate can be removed, cleaned and dried separately, and then reinstalled. Compared with traditional air purifiers where the entire base plate needs to be removed to remove the filter, this utility model allows for the separate removal of the frame plate and the filter plate, making filter plate replacement or cleaning more efficient and simpler to operate."

[0005] Regarding the aforementioned technologies, the inventor believes that considering only the ease of replacing the filter plate does not take into account the significant noise generated by the fresh air unit during operation, which affects the rest of indoor occupants. Furthermore, the method of directly disassembling and cleaning is too cumbersome. Therefore, there is an urgent need to improve a small-scale condensing heat recovery fresh air unit to solve the above problems. Summary of the Invention
