  • Improving energy efficiency: About oil fouling in refrigeration systems

    Introduction Most air conditioning and refrigeration systems have a mechanical compressor which relies upon lubricating oil to function. During the normal course of the refrigeration process, ½% to 8% of the compressor’s lubricating oil is circulated throughout the system along with the refrigerant. Since the early days of refrigeration and air conditioning technology, the ...

  • 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 ...

  • 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 ...

  • Scientists call manmade chemicals like refrigerant gases a cause of climate change

    A major cause of climate change is the harm that is done to the Earth by man-made chemicals. Whilst chemicals, such as those used to produce day by day items, operate equipment and generally make life easier, are necessary, they present a threat to the environment. Governments around the world have set new regulations to limit the use of substances that contribute to global warming and deplete ...

  • 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 ...

  • Energy efficiency: la Compagnie des Fromages counts on innovation with Emerson technologies

    The subsidiary of the Bongrain Group is pursuing a policy to reduce its energy usage and CO2 emissions by investing in a facility designed by Cofely Axima, a leader in industrial refrigeration and a subsidiary of GDF Suez. This solution stands out for its use of a process that heats and cools within a single cycle and its use of key components supplied by the Emerson Group – a Vilter ...

  • The oil intensity of food

    Today we are an oil-based civilization, one that is totally dependent on a resource whose production will soon be falling. Since 1981, the quantity of oil extracted has exceeded new discoveries by an ever-widening margin. In 2008, the world pumped 31 billion barrels of oil but discovered fewer than 9 billion barrels of new oil. World reserves of conventional oil are in a free fall, dropping every ...

  • Where does the oil go after treatment with the SRA?

    Oil is necessary in a refrigeration unit; it is needed to lubricate the compressor pump. Over time, much of this oil has circulated through the pipes of the refrigeration circuit and clings to inner walls of the pipes that carry the refrigeration liquid or vapour. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) calls the oil that clings to the inside walls ...

  • Eliminate Degassing When Measuring Viscosity of Compressor Oils

    Compressor oils can create unique challenges when trying to measure viscosity. Dissolved gases from refrigerants, in particular, tend to bubble out when these oils are measured using traditional viscometers. This can create errors in the measurement, typically causing readings to be much lower than they should be. One way to get around this problem is to allow the oil ...

  • Oil refinery vapour gas case study

    1.0 Evaluation of Refinery Gases Various refinery gases are generated in the process of oil refining. These vary, depending upon the type of crude oil being distilled, such as Reduced Crude distillation, or Naphtha cracker. For the purposes of this case study the description and range of refinery gases are those gases produced from refining Crude Oil and Reduced Crude only. Crude ...

  • Achieving

    Introduction The leak repair requirements, under Title VI Section 608 of the Clean Air Act Amendments of 1990, require that when an owner or operator of an appliance that normally contains a refrigerant charge of more than 50 pounds discovers that refrigerant is leaking at a rate that would exceed the applicable trigger rate during a 12-month period, the owner or operator must take corrective ...


  • Effect of storage conditions on physico-chemical properties and fatty acid ratio, C18:2/C16:1 of blended fat

    Hydrogenated palm kernel oil (HPKO) blended with butter in ratio 3:1 and 3:2 were investigated for different physicochemical properties and fatty acid ratio, C18:2/C16:0. The antioxidant treated samples and the control samples, packed in LDPE bags, PET and glass jars were stored at room and refrigerating temperature for ten months. Storage of control samples in LDPE bags at room temperature was ...
