Résumé

This report was prepared as an account of work sponsored by ARTI under its "HVAC&R Research for the 21st Century Program". The main purpose of the study was to investigate the role of filtration in maintaining clean heat exchanger coils and overall performance. Combinations of 6 different levels of filtration and 4 different coils were tested at 4 different air velocities. The experimental results for pressure drops and heat transfer coefficients were correlated and the correlations were implemented within computer models of prototypical rooftop air conditioners and used to evaluate the impact of fouling on cooling capacity and EER. Extract from the table of contents: experimental equipment and procedures (selection of test coils; filters and equipment; test facility; instrumentation; data acquisition and control system); test results (air-side pressure drops/heat transfer coefficients and fouling factors for wet condition; comparison between dry and wet conditions); indoor-air quality effects; equipment performance effects.
