Heating and cooling rooftop Air Conditioning systems is designed as an all in one solution and additionally useful for consolidating space. Roofop air conditioning systems are popular in regions where construction favors a single cabinet system rather than a split Air Conditioner system, which has both an outdoor and an indoor unit. Typically, Amrta rooftop air conditioning is installed outdoors at ground level. In certain instances they may also be installed on the roof for horizontal or down flow designs. Unlike Ducted Split Unit, in a packaged system, most components are in one cabinet. Whether you're looking for cooling only, heat pump type or heat recovery type, we have the right choice for you.

Heating and Cooling Air Conditioning Systems

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.
● 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.

* Performance values refer to the following conditions:
Cooling: room air temperature 27.0°C DB RH 50%, ambient air temperature 35°C;
Heating: room air temperature 20.0°C DB, ambient air temperature 7°C DB / 6°C WB.
** Noise level measured by adopting average value in the noise lab with background noise of 25 dB(A), at a distance of 1.5m high fan speed.
