Maria Yzabell Angel Palma from the Philippines is the inventor of the AirDisc Air Conditioning Technology that uses air as the refrigerant and only consumes very low energy of 150 watts. More especially, it is the timely answer to the Kigali Amendment to the Montreal Protocol for which the United Nations mandates to phase out chemical refrigerants.

Efficient and affordable air conditioning units are vital for both developed and developing countries to reduce detrimental environmental and health effects of chemical refrigerants.

Widely used refrigerants are considered as super greenhouse gases since one kilogram of it is roughly as much as 20,000 kilograms of carbon dioxide when global warming potential is taken into account.

Existing air conditioning units are based on a closed system air conditioning technology that use piston or rotary compressors with high pressure and low volume that requires a lot of energy; this redounds to expensive operational and even maintenance costs to users, and even prohibitive to those wishing to avail of air conditioning.

AirDisc Air Conditioners avail of a technology that is based on a scientific fact that when air molecules are compressed, they generate heat. AirDisc offers a disc-shaped centrifugal compressor that use air molecules with their attendant moistures as refrigerant. All air molecules from a given room, after direct heat removal, are then fully discharged back into the room. As such, it uses a low power rating electric motor that allows users the benefit of low energy consumption.

With air as the cooling medium, there will be zero global warming potential and no environmental or health threats. Residential, commercial, and industrial establishments as well as the air conditioning industry will benefit hugely from the aforementioned features.

When this AirDisc is launched, assembly type mass production will be implemented; this will benefit a lot of people especially the laborers and other stakeholders.
