Types of rooftop air handling units

It is named because it is mostly installed on the roof. In fact, it is also often installed in outdoor areas around air-conditioned rooms. Compared with water-cooled cabinets (water-cooled package air conditioner), it is easier to install than water-cooled machines because it does not require the installation of a cooling water system. It is particularly suitable in areas with water shortages. Compared with air-cooled units, it has an integral structure, which shortens the length of the system pipeline, thereby improving the cooling efficiency and system reliability. Since the whole machine is installed outside the house, it does not occupy valuable indoor space, and there is no noise when the unit is running indoors. Therefore, it has gained wide popularity abroad.
