Bilal Ahmed Qureshi, Auteur ; Syed M. Zubair, Auteur |In this paper, thermoeconomic considerations are given to heat exchanger inventory allocation in vapor compression cycles with mechanical subcooling. Investigation is made with respect to constant work rate, heat rejection and cooling rates as w[...]
