  • A hybrid MCDM approach to supplier selection

    An organisation's progress strongly depends on the selection of an appropriate supplier. The selection of suitable supplier is a multi criteria decision making (MCDM) problem, which is based on several qualitative, quantitative and even conflicting criteria. This paper aims to propose a hybrid MCDM technique for the supplier selection problem. The fuzzy analytical hierarchy process (FAHP) is used ...

  • Innovation of the Month: Food Fermentation for Biopreservation

    Although the word “bacteria” is usually associated with sickness and disease, it is the driving force behind fermentation, a food process on which humans have relied for millennia. Some of the earliest recorded instances of fermentation come from East Asia where, according to William Shurtleff, founder of the ...

  • Use of ejectors in cascade refrigeration systems for exergetic performance improvement

    In this paper an expansion cascade refrigeration system are compared to cascade systems using ejectors. This comparison is made for a variety of fluids. Natural fluids and hydrofluorocarbons (HFCs) are used in the two loops. Theoretical models are written using FORTRAN. The thermodynamic parameters of fluids are given using the software REFPROP 8.0. For fixed working conditions, using CO ...

  • Irreversibility analysis of a compression refrigeration cycle using natural refrigerants for a sustainable future

    Irreversibility analyses of R290, R717, R718 and R744 are carried out in a compression refrigeration cycle. The effects of evaporator temperature, condenser temperature and isentropic efficiency on the irreversibility of the cycle and its basic components are investigated and exergy analysis of the cycle is also presented as a function of evaporator and condenser temperatures. The ...

  • Thermodynamic and thermoeconomic analysis of subcooled and superheated vapour compressed refrigeration system using R152A, R410A and R600A

    In this study, thermodynamic and thermoeconomic analysis procedures are applied to a subcooled and superheated vapour compression refrigeration system for different refrigerants. By thermodynamic analysis, Coefficient of Performance (COP), irreversibilities and exergetic efficiencies of a theoretical refrigeration system are determined to evaluate the system performance. With the thermoeconomic ...
