The compressor motor forces a gas at high pressure through a heat exchanger (to outside) a→ (condenser)on the outside walls of the refrigerator where QH is given i from off and the gas cools to become Inside liquid. The liquid passes from a high-pressure region to soils to low-pressure tubes on the inside Low pressure walls of the refrigerator; the liquid High pressure evaporates at this lower pressure and ap thus absorbs heat(2.)from the inside of the refrigerator. The fluid returns to the compressor where the cle begins again. (b)Schematic diagram, like Fig 20-8 Compressor Plug Motor pl motor ug
