Detailed explanation-1: -This refrigerant gas is very popular and widely used in modern-day’s refrigerators. It is condensed quite effectually. That’s why it can easily cool down the machine’s surroundings and not create the ozone-depletion problem.
Detailed explanation-2: -While R-12 was once the go-to choice for residential/domestic refrigeration systems, Freon™ R-134a refrigerant is now most commonly used. Its versatility allows it to work in home systems ranging from small under-the-counter refrigerators to family-sized refrigeration/freezer systems with multiple cooling compartments.
Detailed explanation-3: -Freon is used in the fridge to absorb warmness from the interior to exhaust outside. Both chlorofluorocarbon and hydro chlorofluorocarbons are responsible for producing greenhouse gases and harm the ozone layer.
Detailed explanation-4: -A nonflammable gas, known as Freon, undergoes an evaporation process again and again within most refrigerators in order to keep the temperature low. The same cycle is used for air conditioners.
Detailed explanation-5: -Ans. In modern refrigerators, Tetrafluoroethane R-134a, and Freon R-438A are the most common refrigerant gas used in India.
