Abstract

Air-Cooled heating and cooling Coils include Condenser and Evaporator. The Green Energy and Environment Research Laboratories of the Industrial Technology Research Institute (GEL/ITRI) have gained many years of practical experiences and have established a complete and detailed database from the test results of heat exchangers. With the data source from testing, we build the simulation software to be used for the air-cooled heat exchanger under Windows Environment. This software has the potential power to save a great deal of time and costs resulted in trial and error during the processes in heat exchanger design and development for manufactures. This technology presents mathematic models and numerical method to calculate the performance of the air-cooled heat exchangers. To effectively improve the performance of air-cooled heat exchangers, passive enhancement techniques are often employed. The methods are (1) by using enhanced fin/tube surfaces; (2) by increasing total surface area; (3) by increasing the effective mean temperature difference between the air flow and refrigerant flow. The technology provides detailed analysis on heat transfer, air-side pressure drop, and internal tube pressure drop. The calculated results closely match the experimental data.
