Chair:
Ersin Gercek, P.E., Real Engineering Services LLC
Technical Committee: 08.03 Absorption and Heat Operated Machines
This session on absorption systems explains the working principle and an overview of the cycle, classification and types of absorption chillers and heat pumps. It also provides an overview of what makes modern absorbers different from those of the past. A case study is added where an absorption chiller is coupled with a CHP plant at a large retail store to increase energy efficiency and resilience.
1 Modern Commercial/Industrial Absorption Capabilities as Showcased in a Big Box Retail Store Application
 |
Douglas A. Davis, Broad USA |
An overview of what makes modern absorbers different from absorbers in the past. How these differences result in a wider suitable application range to solve problems and provide solutions to the HVAC and CCHP marketplace. A recent project for a retail big box store will be covered that does a good job of highlighting these changes and how the store's HVAC, domestic hot water and “sub-cooling” of the low temperature refrigeration is accomplished by the absorbers in a fully integrated CCHP system. This store can also operate with or without the local electric grid.
2 Lithiumbromide Water Absorption Heat Pumps for Heating Applications

Rajesh Dixit, Johnson Controls, Inc. |
This presentation on absorption heat pumps (Lithium Bromide-Water) explains the working principle and an overview of the cycle, classification or types, energy balance, construction/illustration of the equipment, technology benefits and constraints, coefficient of performance, crystallization, lift, applications and application considerations.
