in the refrigerant cycle there are five basic components: fluid refrigerant, a compressor which controls the flow of refrigerant ,the condensor coils which is on the outside of fridge , the evaporator coils which is on the inside of fridge & something called an exapansion device .. The compressor constricts & Refrigerant vapour, raising its pressure & pushing it into the coils on outside of refrigerator.When the hot gas in coils meets the cooler air temperature of kitchen it becomes a liquid.Now in liquid form at high pressure , the refrigerant cools inside freezer & fridge. The refrigerant absorbs heat inside the fridge , cooling down the air. Last the refrigerant evaporates to a gas, then flows back to compressor where the cycle start all over.
