Quality Engineering Procedures Applied to Determine the Weight of Influence of Factors on Microtrigeneration Systems (mCCHP)

Abstract

Microtrigeneration systems are characterized by simultaneous generation of power, heat and cold for small applications (<50kW) and are designed for reducing GHG and other emission degreases. The cooling generation by absorption or adsorptions of heat is the most sensible stage of mCCHP systems.The paper si based on the global mathematical model for a mCCHP system with thermal prime mover. The conceptual design of an mCCHP and was estabilished the influenece factors over the global efficiency of the system. The weight of influence factors was made using a Quality Engineering procedure (typised orthogonal array. An adequate mathematic model (ANOVA) was used for weight of factor influence prediction, with a view to global efficiency maximization. The simulation results showing signal and noise factors and these results are important for system design, selection of subsystem, selection of materials and optimal regime settings.
