Performance analysis of green engine-driven systems for space cooling

As fuel prices keep changing and energy reserves keep decreasing, efficient methods of energy utilisation and conversion should be used. Heat pumping is a good example where low-grade diluted thermal energy is abstracted from air outdoors and then transferred and concentrated at higher air temperature indoors. For space cooling, the thermal energy is abstracted from warm air indoors and then thrown outdoors. This work covers engine-assisted cooling systems both vapour compression and absorption, associated with gas turbine and internal combustion engines. Primary energy was found to be saved by about 50%, especially with gas turbines, relative to the basic electrical system operated by supplied electricity from the power plant.
