A 19-year-old Filipino student has invented an energy-efficient air conditioning unit that does not use hydrofluorocarbons.
In fact Maria Yzabell Angel Palma, a mechanical engineering student at De La Salle University – Manila, developed an air conditioning unit that did not use any chemical refrigerant whatsoever, Philippine Lifestyle News reported.
Palma said she invented the AirDisc technology in 2016 as a research project while she was at the Philippine Science High School. Her invention employs low compression pressure and a high volume of air molecules instead of using a cooling agent.
Regular air conditioning units use hydrofluorocarbons as a cooling agent, which can be harmful to people. Palma’s invention was recently recognized by the International Federation of Inventors’ Association.
Palma, along with her father who is a mechanical engineer, have already filed plans with the United States Patent and Trademarks Office and are now looking for partners to commercially develop the AirDisc air conditioner.
