  • Rooftop Air Conditioning Unit

    Roof mounted air conditioning unit is a large and medium-sized integrated air conditioning equipment with built-in cooling source and air cooling. Named after its frequent installation on rooftops, it is also commonly installed in outdoor spaces around air-conditioned rooms.

    Compared with traditional water system air conditioning, it does not require heat exchange through an intermediate medium, reducing unnecessary water pipeline equipment in the middle, and increasing the evaporation temperature on the evaporation side, thereby improving the refrigeration efficiency of the unit. Compared with traditional split air conditioners, due to its integral structure, there is no need for professional operations such as on-site welding, vacuuming, and refrigerant addition, which reduces the skill requirements for construction personnel and improves system reliability. As an integral unit, it can be used as long as it is connected to the air duct and power supply, greatly shortening the construction period of air conditioning projects. It is installed outdoors, does not occupy valuable indoor space, and produces noise when there is no unit operating indoors.
