OPTIMISATION AND DESIGN OF 1-TON SOLAR AIRCONDITIONING PLANT

Abstract

The preseat invcsti.pe,)ion pertains to the analytical study of the performance of me ton solar operated lithium bromide-water vapour absorpt.'.an airconditioning system for optimization and design effect of following variables on generator heat required ':.ao been studied (i) Generator temperature (ii) Condens erS Absorber temperatures and (iii) Evaporator temperature. T'ie effect of above temperatures, solar collector tilt and r.umbnr of glass covers on collector area also has boon studied, Tie various combinations are investigate'. to optimize these /ariables for best-results, The most import an c,,.riabl-- in the solar absorption refrigeration system has been foti id to be the temperature inside the generator followed by .:umber of glass covers and cc- lector tilt„ For c~.ch operati .g condition there is an optimum generator temperature at rhich minimum collector area is req.uirod to produce the r,q.uirod cooling. Number of glass covers and collector tilt ' 3 important as these affect the useful heat gain in cc lector. The effect of various parerers are reported in the form of some representative grap). ; stowing the variation in performance of the system as func,ionti of those parameters.. Optimum thermal design of tl sy"tim for Roorkee is also carried out in this work,
