Effects of Non-Uniform Refrigerant and Air Flow Distributions on Finned-Tube Evaporator Performance

摘要

An experimental investigation was implemented to determine the capacity degradation due to non-uniform refrigerant and air flow distributions, and to assess the potential to recover the lost capacity via controlling refrigerant distribution between individual refrigerant circuits. The tests were performed on a three-circuit, three depth- row, finned-tube evaporator. Refrigerant inlet quality, exit saturation temperature, and exit superheats for the individual circuits were controlled.
