Performance evaluation of absorption chiller using LiBr+H2N(CH2)(2)OH+H2O, LiBr+HO(CH2)(3)OH+H2O, and LiBr+(HOCH2CH2)(2)NH+H2O as working fluids

Abstract

In order to check the theoretical performance of new working fluids LiBr + H2N(CH2)(2)OH + H2O, LiBr + HO(CH2)(3)OH + H2O, and LiBr + (HOCH2CH2)(2)NH + H2O [LiBr/H2N(CH2)(2)OH, LiBr/HO(CH2)(3)OH, and LiBr/(HOCH2CH2)(2)NH mass ratios were 3.5] which were developed particularly for the air-cooled cycle operation, the theoretical coefficients of performance (COPs) were calculated at various operating conditions. The cooling capacity and crystallization problem were also checked at a specific condition for air-cooled cycle operation. All the solutions were found to be of possibe use as working fluids for the air-cooled absorption chiller as alternatives to the conventional LiBr + H2O solution (C) 1998 Elsevier Science Ltd.
