Abstract

A second-law analysis of a wet crossflow heat exchanger is performed for various weather conditions. The heat exchanger can be used as an energy-saving device for ventilation in air-conditioning. The heat and mass transfer is solved by using the model developed by Holmberg. The effectiveness, exergy recovery factor and second-law efficiency of the wet heat exchanger are individually defined. The effects of lateral solid heat conduction on the effectiveness, exergy recovery factor and second-law efficiency are numerically investigated for various operating conditions. Two optimum design criteria, one for the maximum second-law efficiency and the other for the maximum exergy recovery factor, are obtained.
