Product description
Air Conditioning Rooftop Packaged Unit allow you to confidently replace outdated Air Cool Chiller Rooftop Air Conditioner simply and
affordably - saving time, money and materials by fitting directly on pre-existing, competitive curbs without the need for a
transition. The HVAC Parts Rooftop Packaged Unit provide a hassle-free solution.
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.
Timing on/off
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°CG4 filter, plate and bag filter
07. Economizer and Free Cooling.
It is one of the most important features of this rooftop 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.
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 rooftop packaged unit.
