20-4 Refrigerators, Air Conditioners, and Heat Pumps
{"Image DocumentName": "20-4 Refrigerators, Air Conditioners, and Heat Pumps", "Image ImageDescription": "This figure shows more details of a typical refrigerator. Figure (a) Typical refrigerator system. The electric compressor motor forces a gas at high pressure through a heat exchanger (condenser) on the rear outside wall of the refrigerator where QH is given off and the gas cools to become liquid. The liquid passes from a high-pressure region, via a valve, to low-pressure tubes on the inside walls of the refrigerator; the liquid evaporates at this lower pressure and thus absorbs heat (QL) from the inside of the refrigerator. The fluid returns to the compressor where the cycle begins again.
