Abstract

The paper presents a theoretical evaluation of the performance effects resulting from the installation of a liquid-line/suction-line heat exchanger (LLSL-HX). It examines cycle parameters and refrigerant thermodynamic properties that determine whether the installation results inimprovement of COP and volumetric capacity. The study shows that the benefit of application of the LLSL-HX depends on a combination of operating conditions and fluid properties - heat capacity, latent heat, and coefficient of thermal expansion - with heat capacity being the mostinfluential property. Fluids that perform well in the basic cycle aremarginally affected by the LLSL-HX, and the impact on the coefficientof performance and volumetric capacity may be either positive or negative. Fluids performing poorly in the basic cycle benefit from the LLSL-HX installation through increase of the coefficient of performance and volumetric capacity.
