  • Correlation model of hourly diffuse solar radiation based on ASHRAE model: a study case in India

    Measurements of diffuse and global solar radiation carried out from January 2001 to December 2005 at Ahmedabad, Mumbai, Calcutta, Chennai and Pune cities of India, representing varying weather conditions of the entire country, have been used to develop the correlation model for the estimating hourly values of diffuse solar radiation on horizontal surface. The comparisons of the present estimated ...

  • 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 ...

  • 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 ...

  • How does the Synthetic Refrigerant Additive (SRA) Affect Maintenance and Wear?

    This document describes how SRA affects the maintenance and wear of an air conditioning system into which it is installed. There are two synthetic catalysts in SRA: The major catalyst is one which removes the oil-fouling plaque. This plaque is extensively described by ASHRAE. The second is an advanced lubricity agent. The advanced lubricity agent is several ...

  • 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. ...

  • Preparation of thiabendazole standards for use in applications of the benomyl/carbendazim rapid assay

    GENERAL COMMENTS: This procedure describes the preparation of thiabendazole (TBZ) standards used in applications of the Benomyl/Carbendazim RaPID Assay. Standard concentrations of 10, 50 and 250 ng/mL (ppb) TBZ and a control concentration of 100 ppb TBZ are prepared by making appropriate dilutions of a concentrated TBZ solution in the Benomyl/Carbendazim Sample Diluent. The standards and ...


  • Ahold emissions baseline (case study)

    Executive Summary Verisae helped Ahold develop an understanding not only of Ahold’s direct emissions impact, but also the impact of the supply chain and consumers. Ahold worked with a number of external consultants Arthur D Little, DHV, ERM and Verisae to analyze the information and develop goals and targets in the area of climate action.
