Filipino Invention: Eco-friendly Airconditioner called AirDisc

While working for an eco-friendly oven for a school project when she was in grade 10, Maria Yzabell Angel Palma stumbled on the idea of making an airconditioner that does not use ozone-depleting coolants. Two years later, the AirDisc was born and she became known far and wide.

AirDisc is a green technology. It uses low compression and high-volume air molecules to generate cool air in place of hydroflourocarbons (HFCs) that contribute to global warming.

“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,” she said in an interview with Rappler.

Another beneficial feature of AirDisk that distinguishes it from ordinary airconditioners is its low power consumption and very low maintenance expense. Palma claims that her prototype can consume only 150 watts or ten percent of what a conventional aircon consumes.

With help from the Department of Science and Technology (DOST), the AirDisc is already registered at the Intellectual Property Office both in the Philippines and the United States.

Palma has already reaped a lot of awards for her invention. Among them are the following:
James Dyson Award
International Federation of Inventors’ Association (IFIA)
International Intellectual Property Invention
Innovation and Technology Exposition Thailand 2018
World Inventors Contest 2017 in South Korea
International Invention Innovation Competition 2017 in Canada
DOST Youth Excellence in Science Award 2018
Jesse M. Robredo Youth Award 2018

Maria Yzabell Angel Palma is now enrolled at the De La Salle University in Manila taking up Mechanical Engineering. She finished high school from Philippine Science High School (PSHS) Bicol campus in Camarines Sur Province. Her father, Bernardo Palma, is an entrepreneur with business in the food industry.
