Fouling on the air-cooled outdoor coil of unitary equipment is believed to reduce capacity and efficiency of the system. ASHRAE RP-1705 quantified the impacts and established a method to realistically simulate fouling in the laboratory. This seminar presents highlights of the project, and follow-on work studying the effect of fouling on frost formation of heat pump evaporators. One surprising finding was that in many cases, fouling improves the performance of the coil, even though it reduces the airflow rate. An online article about these findings has reached over 70,000 readers and republished in dozens of newspapers worldwide.
