Rooftop Unit Cooling and Heating are designed for outdoor installation. Only utility and duct connections are required at the point of installation. Field-installed electric heater accessories are available to provide electric heat, if required.
Free Cooling Rooftop Air Conditioning, all model sizes share a common, compact design cabinet in a single footprint. The installer has the flexibility of setting one curb and placing the
proper tonnage unit on that curb after the internal load has been determined. Field convertible duct connections from side shot to down shot allows the installer to have greater flexibility with less inventory.
Commercial HVAC Rooftop Packaged Cooling. Installation time and costs are reduced by easy power and control wiring connections. The small base dimension means less space is required on the ground or roof, plus, the installer can fit this unit between the wheel wells of full size pick-up truck.
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.
