roof top air conditioner Application:
It is mainly applied to hotel, factories, schools, auditoriums, warehouses, etc.
roof top air conditioner Features:
1. Air cooled rooftop ac is applied to dry areas.
2. This rooftop ac is with compact structure, installed on the roof, convenient for installation, occupy no indoor space.
3. Sufficient external static pressure, suitable for connecting air duct system, reduce indoor noise greatly.
4. Different series of rooftop ac, meet different requirements.
5. The framework of this air cooled rooftop ac is anti-cold bridge aluminum alloy, which eliminates cooling leakage and condensate water due to large temperature difference between inside and outside.
6. The main parts of this rooftop ac are imported quality products, with excellent performance.
7. The evaporator and condenser adopts technology of enhancing heat transfer, which makes the exchanger high efficiency and save energy.
roof top air conditioner Structure:
1. Panels and frame are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents.
2. Direct expansion coils with condensate drain tray.
Hermetic compressor
1. High efficiency scroll compressor for the whole range, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers.
2. Ripple type acoustic insulation for compressor section, and thermal insulation for coil and fan section, low noise.
Centrifugal fan
1. Forward curve centrifugal fans for air treatment section and axial fans for condensation section.
2. Front, side and underside air discharge of the treatment unit.
3. High external pressure, long air supply distance.
