Absorption Cooling Optimizes Thermal Design for Cogeneration
MetadataShow full item record
Contrary to popular concept, in most cases, thermal energy is the real VALUE in cogeneration and not the electricity. The proper consideration of the thermal demands is equal to or more important than the electrical demands. High efficiency two-stage absorption chillers of the type used at Rice University Cogen Plant offer the most attractive utilization of recoverable thermal energy. With a coefficient of performance (COP) up to 1.25, the two-stage, parallel flow absorption chiller can offer over fifty (50) percent more useful thermal energy from the same waste heat source--gas turbine exhaust, I.C. engine exhaust and jacketwater, incinerator exhaust, or steam turbine extraction.
