Description

TECHNICAL FIELD

[0001] The utility model relates to air treatment technical field, concretely is a kind of top-mounted air handling unit. BACKGROUND

[0002] The top-mounted air handling unit is a device used to control the temperature and air quality of the internal environment of a building or equipment. It is usually installed on the top of the equipment and ensures the temperature stability of the internal space and the maintenance of the positive pressure environment through a series of air handling and temperature regulation systems.

[0003] The inlet primary efficiency filter is the first filtering barrier of the top-mounted air handling unit, mainly used to remove large particulate pollutants in the air, such as dust, dirt, hair, etc. Its main function is to reduce the number of larger particles in the air, protect the subsequent high-efficiency filter and prolong the service life of the high-efficiency filter. Due to its low filtering efficiency, the inlet primary efficiency filter is usually only used to remove coarse pollutants. When air passes through the inlet primary efficiency filter, the fiber mesh or filter medium on the surface of the filter will have an adsorption effect on particulate matter. Larger particles cannot be diverted with the airflow and will collide and adhere to the surface of the filter medium. This process mainly relies on physical interception and inertial collision effect. Over time, the filter surface will accumulate more and more dust and particulate matter, causing the filter medium to gradually fill up, reducing the porosity and reducing the air flow space, thereby affecting the air flow of the filter. When the filter surface is too dusty, its performance will decrease significantly, the air flow will be limited, and the operating efficiency of the air handling unit will be reduced. The increased resistance of the filter will cause the fan to overload, the pressure to be unstable, the energy consumption to rise, and even cause equipment failure. Therefore, regular cleaning of the inlet primary efficiency filter is crucial to maintaining the normal operation of the unit and reducing the burden on the equipment. However, regular shutdown inspection and cleaning can also cause some inconvenience, especially in high-load working environments (such as hospitals, data centers, etc.). During the shutdown period, the equipment cannot continuously provide the required temperature and humidity regulation, which may affect the indoor environmental quality and even interrupt the production or work process. This not only causes the equipment to shut down, but also requires additional manpower and time to clean and maintain. Therefore, although cleaning the filter is an important step in maintaining the operation of the unit, the downtime and manpower waste caused by it also need to be optimized and reasonably arranged to reduce the impact on normal work.

[0004] In view of this, we propose a top-mounted air handling unit. UTILITY MODEL CONTENT
