Thermodynamic Analysis of a New Air Refrigeration Cycle Combined with a Dew-point Evaporator
A new type of air refrigeration cycle combined with a dew-point indirect evaporative cooler (IEC) is proposed. Corresponding thermodynamic calculations on the new cycle were carried out. A comparative analysis was carried out with the ordinary air refrigeration cycle and NH3 vapor compression cycle. The influences of operation conditions on the performances of the air refrigeration cycle before and after combining the dew-point IEC as well as the COP of the NH3 vapor compression cycle were analyzed. The results showed that the performance of the new air refrigeration cycle combined with the dew-point IEC was greatly improved. The maximum COP can be increased by 37.8% under the design conditions. In addition
compared to the NH3 refrigeration cycle
it can operate with simpler processes and equipment.
