| Video Discription | When a liquid evaporates it absorbs heat and when a gas condenses to a liquid it releases heat. Refrigeration is based on this concept of heat exchange. A liquid refrigerant such as R-134a in your refrigerator or freezer is passed through an expansion valve where some of it changes to a gas causing the remaining refrigerant to cool. Next it passes through an evaporator coil and absorbs heat from inside of the unit as it changes completely to a gas. Heat is released outside the unit when the gas passes through the compressor and condenser. During this process the refrigerant changes back to a liquid and the cycle is repeated. K3d85yNE_RQ |
