Abstract:
Com pleteness and effic iency o f energy app lica tion ( Exergy Effic iency) are cons ide red from therm odynam ic aspec t, and m in imum inv estm ent and opera tiona l expenses from econom ic aspect. The tw o aspec ts are com prehensively taken into consideration in th is paper, and are used as the ev idence o f me thod adopted in the perform ance exper-i m en t o f po sitive d isplacem ent refr ige rant compresso r condensing units. Discussion is fo cused on the tw o w ide ly-app lied expe rim en tm ethods w ith secondary refrige rant ca lor im eter and w ith secondary flu id ca lor im eter, and ana lysis and com par ison a re m ade w ith the help o f the charts o f exergy currency. From the tw o aspects of therm odynam ics and econom ics, an integrated eva luation has been produced fo r them ethods of pe rfo rm ance experim ent of positive d isp lacement refrige rant com pressor condensing units, prov id ing ev idence, based on ex ergy ana ly sis, fo r choo sing m ethods o f pe rfo rm ance exper im ent o f positive displacem ent refr igerant com pressor condensing units.
