Indirect Evaporative Cooling for a Shopping Mall

Project Number ET12PGE3101 Organization PG&E End-use HVAC Sector Commercial, Public Project Year(s) 2013 - 2016
Description
This project was a field assessment of indirect evaporative cooling for ventilation air for a mall in Fairfield, CA in which a new RTU was retrofitted with a direct evaporative pre-cooler at the condenser inlet, and a water to air heat exchanger at the ventilation air inlet. This study was performed in parallel and/or in sequence with four other studies, all of which assessed the performance of RTUs that employ evaporative technologies in different ways or configurations. These include: • A lab assessment of four direct evaporative condenser pre-coolers, and one air supply indirect evaporative pre-cooler. http://www.etcc-ca.com/reports/laboratory-testing-performance-enhancements-rooftop-packaged-air-conditioners • A field assessment at a big box retail store and grocery in Bakersfield, CA of indirect evaporative cooling units from two different manufacturers applied as retrofits to existing RTUs: http://www.etcc-ca.com/reports/indirect-evaporative-air-conditioners-added-existing-rtus • A field assessment of an indirect evaporative unit, serving as a dedicated outside air supply (DOAS) at a restaurant in Rocklin, CA. http://www.etcc-ca.com/reports/indirect-evaporative-air-conditioning-restaurant • Lab and field assessments of a Munters hybrid unitary dedicated outside air supply (DOAS) system.
