  • Energy and exergy analysis of R22 and its alternatives in a vapour compression refrigeration system

    In this paper, energy and exergy analyses and performance comparison of R22 and its alternatives, R407C and R410A, in a vapour compression refrigeration system (VCRS) have been presented. For this aim, detailed first law (energy) and second law (exergy) analysis of these three refrigerants have been performed. Analyses have been performed for different evaporator (range of -40°C to 0°C ...

  • 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 ...

  • Calculating the cost savings for refrigerant gas leak detection

    The real benefits of refrigerant gas leak detection Following on from the last article, we feel that it’s natural to then discuss some of the practical reasons (cost savings) that will encourage the industry to take action and reduce their F-Gas emissions. Who requires refrigerant leak detection under the F-Gas proposals? There are a ...

  • Performance enhancement of GT–ST power plant with inlet air cooling using lithium bromide/water vapour absorption refrigeration system

    Performance improvement techniques in power generation systems especially in gas turbine–steam turbine (GT–ST) combined cycle (CC) power plants by compressor inlet air cooling prove to be much improvising. In this work, the performance enhancement of CC power plant by inlet air cooling method using lithium bromide–water (LiBr/H2O) absorption refrigeration ...

  • 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 ...

  • Recent USEPA Rulings To Reduce GHGs

    Over the last few months the USEPA has begun to implement rules to reduce greenhouse gas (GHG) emissions. Not the traditional way by having affected facilities measure and reduce GHG emissions, but instead by encouraging operational changes to accomplish the same goal. 2 rulings that can affect businesses are discussed here. 1. Alternative refrigerants. This past December the USEPA announced ...

  • Energy and exergy analysis of a combined transcritical CO2 compression refrigeration and single effect H2O-LiBr vapour absorption system

    A refrigeration system is conceived and analysed wherein high grade waste heat from the gas cooler of a TCRS is utilised to operate a single effect H2O-LiBr VARS. A simulation program is developed for computation of optimum gas cooler pressure of TCRS. The COP and ? ex for individual TCRS and VARS as ...

  • A life cycle greenhouse gas assessment of remanufactured refrigeration and air conditioning compressors

    Remanufacturing can importantly reduce the resource intensity and increase the eco-efficiency of product systems by utilising recovered end of life (EOL) parts. A life cycle assessment (LCA) has been carried out to determine the greenhouse gas emissions from the production of a remanufactured compressor vs. a new original equipment manufacturer (OEM) compressor. The remanufacturing consisted of ...
