Product Description

Free cooling also called ecomonimzer, which is energy saving, based on air conditions, can provide outside air to cool the space. Amrta Air Conditioner with a cooling capacity of up to 65kW sold in Australia or New Zealand must now comply with the Minimum Energy Performance Standards (MEPS), as set out in Australian and New Zealand Standards. Amrta Rooftop Packaged Unit exceed MEPS requirements, in line with Amrta's commitment to providing energy efficient, quiet, simple to use and reliable Air Conditioning Solutions.

Characteristics

01.Structure. Panels and frame are made from galvanized steel protected with polyester powder painting to ensure total resistance to atmospheric agents.

Economizer and Free Cooling ( Option )

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 packaged unit is supplied with economizer and fresh air hood to improve comfort through better fresh air management and allow energy savings with free cooling.
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.
