Summary

The energy consumption for space air-conditioning bears huge share of total energy consumption around the world. Due to the increasing pressures of energy demand, the degradation of environment, global warming and depletion of ozone layer etc., there is need of efficient energy utilization and waste heat recovery. The researchers are concentrating on the alternate and environment friendly refrigerants, especially after the Kyoto and the Montreal Protocols. In this paper, the investigations on a modified hybrid vapour compression/absorption heat pump system using ammonia-water as the working fluid have been presented. This system can also utilize the non-conventional energy sources such as solar energy and bio-gas in addition to the waste heat from different industries. The theoretical as well as the experimental performance based on the energy and exergy analysis have been investigated.
