Description

Technical Field

[0001] The embodiments of the utility model belong to the technical field of centralized air-conditioning health monitoring devices, and more specifically, relate to an independently distributed centralized air-conditioning health monitoring device. Background Art

[0002] As an important factor affecting the quality of indoor environment, the central air conditioning and ventilation system has always been the focus of public place health supervision. According to the "Implementation Rules of the Public Place Health Management Regulations" (revised in 2017), "Public places that use central air conditioning and ventilation systems shall comply with the relevant health standards and regulations for central air conditioning and ventilation systems in public places". At present, the central air conditioning health inspection specification is the "Health Standard for Central Air Conditioning and Ventilation Systems in Public Places" WS 10013-2023, which divides the health inspection of central air conditioning pipes into three parts: fresh air volume, inner surface of air duct, and air supply. Among them, the inner surface of the central air conditioning duct and the air supply index include physical indicators (dust accumulation) and chemical indicators (PM10 inhalable particulate matter). In daily health management work, the health status of the central air conditioning and ventilation system can only be judged through health inspection. Therefore, a device that assists in the detection of central air conditioning deposition and PM10 indicators is proposed, which is of great significance for the efficient implementation of health inspection work.

[0003] In order to solve the above technical problems, the on-site detection method usually adopts manual sampling at the pipe opening of the air-conditioning system with the help of ladders or rods as auxiliary tools to approximately characterize the overall sanitary condition of the centralized air-conditioning system.

[0004] Although the above technical methods have taken enforcement measures for the sanitary conditions of the central air-conditioning system, the following technical problems or areas for improvement still exist: (1) The manual reaching method is used to contact the sampling site. Due to the small space, this method is mostly limited to the vicinity of the air outlet. It is difficult to accurately touch the internal points of the central air-conditioning system, and it cannot fully and accurately interpret the overall sanitary conditions of the central air-conditioning system. Most monitoring can only achieve the effect of preliminary judgment, which brings hidden dangers to the sanitary supervision work; (2) In view of the problem that the internal space of the central air-conditioning is small and it is difficult for personnel to enter for inspection, it should be considered to pre-arrange measurement points and install small independent sampling devices at the points to complete efficient and accurate sampling; (3) Regarding the improvement direction mentioned in (2), the problem of the flatness of the internal installation surface of the air-conditioning should be solved, which affects the accuracy of the weighing method for measuring dust accumulation. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the utility model provides an independent point-based centralized air conditioning sanitation monitoring device. By designing a lightweight independent device with integrated dust collection, weighing and PM10 measurement functions, the technical problem that the existing method uses manual reaching to contact the sampling site, which is difficult to accurately touch and collect points inside the centralized air conditioner due to the small space, is effectively solved. This makes it possible to pre-install the collection equipment in the centralized air conditioner, and also improves the credibility of the representation of the centralized air conditioning sanitation detection data.
