The vertical air conditioning unit utilizes refrigerants like R22 to produce 7-12°C chilled water through a compressor, which is then supplied to the terminal air handling unit. It comes in two main types: air-cooled and water-cooled. The vertical air conditioning unit is an air treatment equipment assembled from various air treatment sections. It is suitable for air conditioning systems with resistance greater than 100Pa. The air treatment sections include: air mixing, uniform flow, filtration, cooling, primary and secondary heating, dehumidification, humidification, supply and return fans, spray, noise reduction, and heat recovery units. The LIFENG JK series modular clean air conditioning units offer 30 specifications with 12 functional sections for users to freely select and combine. They are mainly used in air purification systems for various clean rooms, such as industrial electronics factories, precision machinery manufacturing plants, textile workshops, food factories, pure water workshops, ICU, and more.
