    Refrigeration Circuit 3.5.1 Standard Operation Starting at the compressor, (see Figure 3.7) the suction gas is compressed to a higher pressure and temperature. The refrigerant gas flows through the discharge line and continues into the air-cooled condenser. When operating with the air-cooled condenser active, air flowing across the coil fins and tubes cools the gas to saturation temperature.
