Heat Transfer and Effectiveness Analysis of a Cross-Flow Heat Exchanger for Potential Energy Recovery Applications in Hot-Humid Climate
- 1 Universiti Sains Malaysia, Malaysia
This paper presents heat transfer and effectiveness analysis based on a physical model of a cross-flow heat exchanger. Using the model, the transferred heat and effectiveness (ε) in terms of temperature and NTU-method are calculated for both hot and cold streams. From the analyses, it is found that as air velocity increases, the transferred heat through heat transfer plates increases. In contrary, when air velocity decreases, the effectiveness increases. Further, as the air temperature of hot exhaust stream increases, both the transferred heat and effectiveness decrease. The study suggests that the calculated results provide benchmark data to evaluate and predict the performance of heat exchanger for energy recovery application.
