INTEGRATION OF AN ABSORPTION CHILLER SYSTEM IN A SUPERMARKET HEATING, COOLING AND POWER SYSTEM
The objective of this investigation was to integrate a pre-engineered Combined Cooling, Heating and Power (CCHP) system into a supermarket application. The CCHP system, which consists of four natural gas-fired microturbines and a double effect absorption chiller/heater, provides electrical power, space conditioning, and sub-cooling of a refrigeration loop to reduce electric power demand. In addition, the exhaust heat from the chiller is used to regenerate a solid desiccant wheel that provides dehumidification of the retail space. Results of an energy analysis indicate that the CCHP system will provide a 65% reduction in grid electric demand. This paper will present a description of the CHP system, detail how it was integrated into the supermarket application, and describe the benefits of using CCHP systems in this application.
