Abstract
The current study concerns the use of azeotropic mixtures in single-stage vapor compression refrigeration system configurations to determine the effect of entrainment ratio on the coefficient of performance. Three singlestage vapor compression refrigeration system configurations are used. The effects of condenser and evaporator temperatures on the single-stage refrigeration system are investigated. The used azeotropic mixtures are: R1234yf + R290, R1234yf + R152a, R1234yf + R600a, R134a + R290, R134a + R600a and R1270 + R134a. It is shown that the simulations results are in good agreement with the literature. The R1234yf + R290 mixture in refrigeration cycle give the highest coefficient of performance and entrainment ratio. The coefficient of performance (COP) increases with increasing of entrainment ratio.
期刊介绍：
High Temperatures – High Pressures (HTHP) is an international journal publishing original peer-reviewed papers devoted to experimental and theoretical studies on thermophysical properties of matter, as well as experimental and modelling solutions for applications where control of thermophysical properties is critical, e.g. additive manufacturing. These studies deal with thermodynamic, thermal, and mechanical behaviour of materials, including transport and radiative properties. The journal provides a platform for disseminating knowledge of thermophysical properties, their measurement, their applications, equipment and techniques. HTHP covers the thermophysical properties of gases, liquids, and solids at all temperatures and under all physical conditions, with special emphasis on matter and applications under extreme conditions, e.g. high temperatures and high pressures. Additionally, HTHP publishes authoritative reviews of advances in thermophysics research, critical compilations of existing data, new technology, and industrial applications, plus book reviews.
