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.
