Solid-State Cooling Technology Offers Eco-Friendly Alternative to Traditional Air Conditioning

Now almost all air conditioners work with refrigerant gas and compressors, but solid-state cooling systems have a completely different approach. This technique does not involve converting gas into a liquid and then back into a gas. Instead, certain solids are subjected to electric fields, magnetic fields, or mechanical pressure, which changes their temperature and causes cooling. AdvertisementSolid-state cooling techniques work on caloric effects. And simply put, when external pressure or fields are applied to certain solid materials, they heat or cool. Advertisement scientists are developing cooling systems using this property. No refrigerant gas is needed, and the whole system can be simplified. The ACs that people are using at the moment contain hydrofluorocarbons (HFCs), gases that are harmful to our environment. These gases can harm the Earth's solid-state cooling technology many times more than carbon dioxide. These gases can harm the Earth's environment.
