Does anyone have any experience using the condenser section of an air-cooled packaged AC unit for smoke purge. Johnson Controls sells a motorized damper for the condenser section to be used to relive room pressure by using room air to cool the compressor.We would like to use this arrangement to do post-fire smoke purge by opening this damper and closing the outside air intake damper in the condenser section.
The compressor would be shut down and the exhaust fan run.
