Abstract

This paper presents results of an experiment conducted to investigate the performance of a newly developed air cooling system comprising a psychometric energy core (PEC), a cooling unit assisted with wind catcher technology. A laboratory unit of the combined system was designed and constructed using a wind catcher and a PEC unit. The purpose of the wind catcher is to assist air flow in and out of the PEC unit. This is achieved using a double concentric hallow ducting system; an outer large circular duct for fresh air supply and a smaller central duct to allow exhaust air from the PEC to exit the system. A series of tests were conducted using a wind tunnel, in order to assess the performance of the system under varying wind speed and ambient temperature. Results of the tests show that the system has a potential of passive operation without the support of a fan under certain wind speeds. A fan would be required at very low wind speed to overcome the pressure drop through the PEC core channels. Copyright The Author 2010. Published by Oxford University Press. All rights reserved.
