Economizer and free cooling is one of the most important features of this Commercial Rooftop Packaged Unit as it maximise seasonal efficiency by reducing the use of thermodynamic cooling in mid season. Thermodynamic cooling can be replaced by Free Cooling when outdoor temperature is below the building set point saving up to 15% on annual energy consumption. Rooftop units are supplied with economizer and fresh air hood to improve comfort through better fresh air management and allow energy savings with free cooling. Characteristics 01.Structure. Panels and frame are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents. Direct expansion coils with condensate drain tray. 02.Hermetic compressor. High efficiency scroll compressor for the whole range, with built-in thermal overload cut-out and crankcase heater, mounted on rubber vibration dampers. Ripple type acoustic insulation for compressor section, and thermal insulation for coil and fan section, low noise. 03.Centrifugal fan. Forward curve centrifugal fans for air treatment section and axial fans for condensation section. Front, side and underside air discharge of the treatment unit. High external pressure, long air supply distance. 04.Electric panel. Electric panel consists of breakers and contactors for compressors and fan motors, phase sequence relay and other necessary protection devices for the main components. 05.Easy operation line controller Cooling/Heating/Auto Error indication Timing on/off 06.Optional Economizer with fresh, return air dampers and fresh air hood Free cooling function for low ambient temperature Low ambient control device for operation of outdoor units at ambient temperatures from less than 20°C down to -10°C BMS devices T3 (Tropical climate) Roof curb metal/aluminum filter 100% heat recovery Evaporating section: double skin with 50mm polyurethane foam Optional water heating coil metal or plastic mesh on condenser coil Optional supply/return air configurations Upgraded plug fan G4 filter, plate and bag filter Exhaust Air Gravity exhaust damper Gravity exhaust damper Installed with economizer assembly, gravity exhaust damper relief pressure when outside air is being introduced in the system. It is a cheap and smart way to avoid over pressure in a building. Power exhaust fans Installed with economizer assembly, it provides exhaust air pressure relief when high levels of fresh air are being introduced in the system. Interlocked to run when return air dampers are being closed and supply air blower is in operation. The extraction fans run when outdoor air dampers are at least 50% open (adjustable). It is also overload protected. A gravity exhaust damper is supplied with this option to prevent air from entering the unit during shutdown. The power exhaust fans have been size to exhaust 50% of the nominal air flow of the unit.
