چکیده

In this paper, a first- and second-law analysis of vapor compression refrigeration is presented to estimate propose the replacement R134 with working fluids having less global warming potential (GWP) exergy destruction irreversibilities. Six different refrigerants were studied, namely, R717, R1234yf, R290, R134a, R600a, R152a. A thermodynamic model was designed on Engineering Equation Solver (EES) software, performance parameters calculated. The deployed all six refrigerants, while used output cooling capacity, coefficient performance, discharge temperature, total destruction, relative rates components, efficiency, efficiency defect each component. estimated at speeds compressor (1000, 2000, 3000 rpm) fixed condenser evaporator temperatures 50 °C 5 °C, respectively. isentropic same as volumetric it taken 75%, 65%, 55% 1000 rpm, 2000 comparison by importing results in MATLAB. It found that had highest compared other components. R152 refrigerant zero ozone depletion (ODP) GWP value 140 Moreover, easy use R152a good characteristics. suitable for can be few modifications.

Comparative Exergy Analysis of Vapor Compression Refrigeration System Using Alternative Refrigerants

Abstract—In present paper, the performance of various alternative refrigerants is compared to find the substitute of R22, the widely used hydrochlorofluorocarbon refrigerant in developing countries. These include the environmentally friendly hydrofluorocarbon (HFC) refrigerants such as R134A, R410A, R407C and M20. In the present study, a steady state thermodynamic model (includes both first and...

Exergy, exergoeconomic and exergoenvironmental studies and optimization of a novel triple-evaporator refrigeration cycle with dual-nozzle ejector using low GWP refrigerants

In this work, a novel dual-nozzle ejector enhanced triple-evaporator refrigeration cycle (DETRC) without separator is proposed to improve the performance of the conventional ejector one (CETRC). The performance of DETRC is analyzed and compared with CETRC in term of energy coefficient of performance (COPen). Under given operating conditions, the COPen improvement of the no...

Transient Exergy Destruction Analysis of a Vapor Compression System

Through online optimization and control, vapor compression systems (VCSs) can effectively respond to disturbances, such as weather or varying loads that cannot be accounted for at the design stage, while simultaneously maximizing system efficiency. However, to do so requires a mathematical characterization of efficiency for the VCS. In particular, we would like to maximize the exergetic efficie...
