U.K. lab promises air conditioner revolution without polluting gases

  • A UK startup called Barocal is developing air conditioners using solid refrigerants based on plastic crystals to reduce emissions.
  • This innovation responds to rising global demand for air conditioning and increasing emissions from leaks and consumption of gas refrigerants.
  • Barocal's prototype, the size of a large suitcase, uses pressure changes in crystal-filled cylinders to produce cooling through the barocaloric effect.
  • The startup has raised about £4 million, plans product launch within three years, and claims their units could cut emissions by up to 75 percent and match gas efficiency.
  • If successful, Barocal’s technology could eliminate greenhouse gases in air conditioning and offer more energy-efficient cooling, initially targeting large facilities.

Devices would be able to reduce emissions by up to 75% compared to traditional units, and cheaper accounts would compensate for higher initial cost The "solid refrigeration" macho studied in a UK laboratory may not seem very impressive, but its incommunity properties promise a revolution in the air-conditioned, which could eliminate the need for dry-effect gases. The temperature of the substance may vary at more than 50°C under pressure. Unlike …
