Ventilation Control by Measurement of Carbon Dioxide Levels in Public Entertainment Buildings. A Demonstration in a Cinema and a Bingo and Social Club Operated by Rank Organisation PLC. Final Report

摘要

To determine the fuel cost savings that would result from reducing ventilation rates during periods of low occupancy, the Rank Organisation retrofitted a variable fresh air ventilation system, controlled by a carbon dioxide (C0 sub 2 ) detector, at a social club and cinema. The detector is linked to dampers which adjust the flow of fresh air into the building to maintain C0 sub 2 levels within limits set to provide an acceptable internal environment. Conversion to C0 sub 2 -controlled ventilation included three main components; an air temperature controller; a variable fresh air ventilation system and a C0 sub 2 detector. Operational experience, the monitoring program, measured results, energy savings and economic analyses are discussed. (ERA citation 12:020486)
