Proceedings <strong>of</strong> the National Conference on<br />

Trends and Advances in Mechanical Engineering,<br />

producing the cooling load <strong>of</strong> 60% <strong>of</strong> above losses in the combination <strong>of</strong> vapour absorption machine. This is the<br />

unique and advanced techniques in itself and it can be said that this system is the self sufficient system.<br />

4. CONCLUSION<br />

Experimental results were obtained from power plant and tri-generation systems. In the power plant, there were<br />

the losses <strong>of</strong> 31.25% as the stack gases but in the tri-generation system 51.7% <strong>of</strong> stack gases was utilized in<br />

operating the vapor absorption machine through a heat recovery unit. The COP <strong>of</strong> the system was 0.52 and room<br />

temperature was between 0 0 C-5 0 C.The thermal power from the engine water cooling jacket (31.25%) was<br />

utilized for heating purposes and the temperature <strong>of</strong> heating medium was noted 60 0 C - 63.5 0 C, while 72% heat<br />

can be recovered through the exhaust gases after heat recovery unit. The total losses in power plant were 68.75%,<br />

in which 62.5% was the recoverable losses. These recoverable losses were reflected in the form <strong>of</strong> cooling and<br />

heating in combined form for tri-generation system. Therefore, results show that power plant combined with<br />

absorption chiller (gases driven into generator through heat recovery unit) gives the better utilization <strong>of</strong> thermal<br />

losses which were in the form <strong>of</strong> stack gases and engine water cooling jacket. This was understood till now that<br />

there is no meaning <strong>of</strong> wastage in the world but this paper has presented useful meaning <strong>of</strong> wastage. It is nothing<br />

but the theme <strong>of</strong> this paper.<br />
