  • The Elimination of Ethylene in Domestic Refrigerators

    Ethylene is a plant hormone produced naturally by fruit and other plant tissues. It is known as the ripening hormone because it regulates the series of processes associated with the ripening and senescence of fruit. Eliminating ethylene from the environment, both in storage chambers and transport containers, where it is stored in the form of gas, is a widespread practice designed to provide a ...

    Vapor Extraction and Refrigerated Condensation was used as a primary source removal technology to remediate high concentrations of recalcitrant chlorinated solvent compounds at the WDE Site in Minnesota. The use of Refrigerated Condensation has achieved high mass removal rates and will reduce the lifecycle costs and time of remediation. History 6,600 drums of hazardous ...

  • A novel hybrid GAX–ejector absorption refrigeration cycle with an air–cooled absorber

    A novel hybrid generator–absorber heat exchange (GAX)–ejector absorption refrigeration (hybrid GAX–E) cycle, with ammonia–water as working fluid, is proposed and analysed in detail. Thermodynamic models are developed for the hybrid GAX–E, hybrid GAX, simple GAX and single effect ammonia-water absorption refrigeration cycles. A comparison among the performances of these four cycles, at an absorber ...

  • Energy and exergy analyses of a new combined cycle using carbon dioxide as working fluid

    In this study, a new combined cycle based on the Brayton power cycle and the ejector expansion refrigeration cycle is proposed. The proposed cycle can provide simultaneous heating, cooling and power. And be driven by low temperature heat sources. The suggested cycle can save energy around 46% in comparison with a system producing cooling, power and hot water separately. Moreover, the second law ...

  • Exergy analysis of hydrocarbons mixture refrigerants R436A and R436B as a drop in replacement for R134a with TiO
    2
    nanoparticles

    The refrigerator exergy efficiency (EE) with nanoparticles in the working fluid was investigated experimentally. Mineral oil (MO) with TiO2 nanoparticles mixtures were used as the lubricant instead of Polyol ester (POE) oil in the R134a, R436A (R290/R600a–56/44–weight %) and R436B (R290/R600a–52/48–weight %) refrigerator. The results indicate that R134a, R436A and R436B and MO ...

  • 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 ...
