Fresh air cabinet
Fresh air cabinetA fresh air cabinet is also known as a fresh air pressure cabinet, fresh air cabinet, etc. The following is a detailed introduction to it:Definition and function Definition: A fresh air cabinet is used to provide indoor air purification equipment, mainly for fresh air pretreatment, to provide enough fresh air for indoor air purification purposes. Feature Air purification: Equipped with a professional air filter to filter the fresh air, which can remove dust, particulate matter, some harmful gases, and other pollutants to ensure that the air sent into the room is clean and dust-free. It can also be configured with high-performance filtration devices according to special requirements, such as high-efficiency filters, activated carbon filtration layers, etc., to further improve the purification effect. Ventilation: Through the built-in supply and exhaust fan, the outdoor fresh air is introduced into the room, while the indoor dirty air is discharged, forming a "fresh air flow field" in the room, achieving a continuous exchange of indoor and outdoor air and improving indoor air quality. Auxiliary temperature and humidity regulation: Some new air cabinets can be combined with air conditioning systems, etc., to a certain extent, the air is simply heated, cooled, dehumidified, or humidified to help maintain a suitable indoor temperature and humidity environment. Working principle Extract fresh air outdoors, let the air after dust removal, dehumidification (or humidification), cooling (or heating), and other treatment, through the fan to the room, when entering the indoor space to replace the original indoor air. This process mainly relies on the power of the fan to drive the airflow, while the air is treated accordingly by the filter system, heat exchanger, humidifier, and other components. Structural characteristics Filtration system: Usually adopts multi-stage filtration system such as initial effect, medium effect, and high efficiency to meet different purification needs. Fan system: Choose the right fan to provide enough air volume and pressure to ensure that fresh air can be smoothly transported to all areas of the room. The fan has the characteristics of low noise, stable operation, and adjustable air volume and pressure. Box structure: Generally made of high-quality cold-rolled steel plate spray, color steel plate or stainless steel, and other materials, with good strength, sealing, and corrosion resistance. The product design is compact and reasonable, small in size, easy to install, and simple to maintain, one only needs to open an access door on one side to perform maintenance operations. Application scenario Medical places: such as hospital operating rooms, pharmacies, wards, etc., need to strictly control air quality to provide a healthy environment for patients and medical staff, and new air cabinets can effectively filter bacteria, viruses, and other microorganisms to ensure clean air. Industrial field: such as biopharmaceutical, LED photoelectric, circuit board, microelectronics, hard disk manufacturing, and other industries with high cleanliness requirements, the new air cabinet can provide fresh air after purification for the production workshop to meet the environmental requirements of the production process. Food processing industry: helps to keep the air of the food processing environment fresh, and reduce dust, microorganisms, and other pollution of food, to ensure food safety. Civil buildings: such as residential buildings, offices, shopping malls, schools, hotels, etc., can improve indoor air quality and provide people with a comfortable and healthy living and working environment. It is also used in the fire pressure air supply of housing buildings, and the pressurization and replenishment of purified air conditioners. |
