  • Refrigerant gas management (case study)

    Executive Summary Refrigerant leaks are one the highest maintenance expenses for organizations using or maintaining gas. In addition to compliance, management of refrigerant is important from a cost perspective. A typical 100-store supermarket chain operates with 400,000 lbs. of refrigerant within their refrigeration and air conditioning systems. Assuming an average cost of $6 per ...

  • EPA mandates proper refrigerant gas recovery processes

    New EPA regulations require facilities that use air conditioning and refrigeration equipment to have a refrigerant recovery plan in place. The plan is needed to make sure that any harmful gases that might leak are captured. Refrigerant gases contain hydrochlorofluorocarbons, known to cause severe damage to the ozone layer and to promote global warming. A comprehensive plan is now in place to ...

  • 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 ...

  • 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 and exergy analysis of reverse Brayton refrigerator for Gas Turbine power boosting

    In this study the use of Reverse Brayton cycle to boost up the power of gas turbine power plants operating in hot humid ambiance is analysed by the energy and exergy methods. The gas turbine inlet temperature is reduced by mixing the chilled air from Brayton refrigeration cycle and the main intake air stream reaching low intake temperatures. In this paper the effect of irreversibilities in the ...

  • Landfill remediation with refrigerants and chlorinated solvents

    PROJECT DESCRIPTION Between 1979 and 1980, industrial and hazardous wastes were disposed of at the Site in a series of unlined pits, each of which was used for a particular type of waste disposal. It is reported based on evaluations of manifests that approximately 3.4 million gallons of hazardous liquid wastes and between 3,700 and 4,100 tons of solid wastes were disposed of in the pits ...

  • Thermodynamic analysis of a hybrid gas turbine/thermoacoustic heat pump/refrigeration engine

    Possible performance enhancement of small gas turbine power plants through the application of thermoacoustic systems is examined. The thermoacoustic subsystem is powered only by the waste heat of the gas turbine. Two different gas turbine configurations are considered: a Thermoacoustic refrigerator assisted gas turbine (TRG) and a Combined thermoacoustic heat pump and refrigeration assisted gas ...

  • Getting ready for the phase out of R-22 (HCFC) refrigerant gas

    Market Demand for R-22 HCFC Refrigerant Gas Will be 20% Higher than Available Supply The HCFC refrigerant gas called R-22 is the most pervasive refrigerant in everyday use around the world. Since the 1940's R-22 has been the refrigerant gas that we use in central air-conditioning (AC) systems at home and work. It is efficient, non-toxic and easy to use. It's difficult to grasp how important ...

  • Exergy analysis of a diffusion absorption refrigeration system

    An energetic and exergetic study on a diffusion absorption refrigerator (DAR) is presented in this paper. It uses ammonia as the refrigerant, water as the absorbent and hydrogen as the auxiliary gas. A computer model has been developed to calculate the thermodynamic properties of all state points, heat flow rates, exergy losses and COP degradation in each component of the system. The system ...

  • Refrigerant compliance includes calculating carbon emissions

    If you manage a facility using a refrigeration and air-conditioning (RAC) system or heating, ventilation and air conditioning (HVAC-R) system, it’s time to comply with federal and state environmental laws regarding carbon emissions. To help reduce greenhouse gases, the law requires calculating carbon emissions. This means monitoring, collecting data and performing extensive reporting of CO2 ...

  • Degassing Refrigerators - Drill-head and Piercing-plier

    1. For what purpose do we have to degas a refrigerator? A refrigerator has to be disposed as hazardous waste. The refrigerants inside a hazardous refrigerator are harmful for the environment (ozone depleting and greenhouse effect). Most common refrigerants are; R12, R134a and R600a. The uncommon is the removal of NH3. Refrigerants are developed to dissolve very easily into ...
