Packaged rooftop unit

Rooftop Air Conditioning Unit is centralized air conditioning products that integrate cooling (heating) sources and air treatment.

Typically of the air-cooled type, these units combine refrigeration systems, control systems, and various air treatment functions to achieve cooling, heating, dehumidification, humidification, noise reduction, air purification, and fresh air delivery. By utilizing heat exchangers within the refrigeration system, these units enable direct heat and moisture exchange between the refrigerant and air,eliminating energy loss from secondary exchanges with intermediate heat transfer media. They do not require cooling towers, chilled (frozen) water pipes, circulating water pumps, or dedicated machine rooms.

These units can be installed as a whole on rooftops, outdoor courtyards, or with separate installations for the compression-condensation and air treatment sections. Roof-mounted air conditioning units are highly suitable for comfort air conditioning systems in venues such as sports arenas, exhibition centers, theaters, conference rooms, malls, airport lounges, and train station waiting areas. They are also widely used in processed air conditioning systems in industries including pharmaceuticals, electronics, food, machinery, and textiles.
