Replaces Polluting Gases
Scientists at the University of Cambridge UK and Universität Politecnica de Catalunya in Spain have come up with a breakthrough in refrigeration/cooling technology. Plastic crystals of neopentylglycol (NPG) that when put under pressure is competitive with conventional coolants. The conventional coolants in refrigerators and air-conditioners are toxic and when released into the air are pollutants.
Our Appliances: A Global Energy and Environmental Issue
Refrigerators and air-conditioners use 20% of the energy produced globally. The vast majority of these appliances use hydrocarbons and hydrofluro-carbons in the cooling system that are toxic, flammable and when released into the air add to global warming.
To solve this cooling problem, materials scientists have sought an alternative solid refrigerant. UK and Spanish scientists believe their plastic crystals NPG coolant system is the answer, which they are now commercializing and bringing to market.
