  • 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 ...

  • Andover, Vapor Extraction and Refrigerated Condensation Case study

    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 ...

  • 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 ...

  • 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 ...

  • Energy Star failings: Much ado about something

    As suspected, Energy Star appliances do not always live up to their energy savings claims, according to preliminary results of laboratory tests reported his week by the US Department of Energy (DOE).   The DOE began testing the appliances after watchdogs raised serious questions about the federal labeling program. The Energy Star seal appears on hundreds of models of refrigerators, air ...

  • Northeast US a smart energy testing ground

    By Elisa Wood August 19, 2010   Ben Franklin’s saying, “Out of adversity comes opportunity” seems to characterize the energy sector in US Northeast. Electricity rates are among the nation’s highest. Population density leaves scant room for new power plants and transmission lines.  And the region has little indigenous generation fuel. So ...

  • Controlling condensation- controlling mold

    You know those water stains on the ceiling tiles in your office that you are certain are caused by a leaky roof. Of course, the maintenance man thinks your crazy, since your office is not on the top floor. He dutifully changes the ceiling tile and a month later the water stain is back but this time it has those little black circles that look like mold colonies. Sound familiar? There seems to be ...

  • Control water – control mold

    There is no single universal way to eliminate all mold growth. But the single most effective method of controlling mold is to eliminate their source of moisture. Moisture doesn’t just mean actual water; it can also be high humidity. Few molds grow when the humidity is under 70%. If they do, it is very slowly. It is safe to say that you cannot stop mold growth until you stop the moisture. ...
