  • 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 ...

  • Energy and exergy analysis of a combined transcritical CO2 compression refrigeration and single effect H2O-LiBr vapour absorption system

    A refrigeration system is conceived and analysed wherein high grade waste heat from the gas cooler of a TCRS is utilised to operate a single effect H2O-LiBr VARS. A simulation program is developed for computation of optimum gas cooler pressure of TCRS. The COP and ? ex for individual TCRS and VARS as ...

  • Leaking Chillers Caused By Condenate Line Gel Blockages

    Refrigeration engineers can be forced to spend up to 50% of their time performing a task so unpleasant and mind-numbingly dull that you would by rights expect to see it on the work plan of a Victorian gutter snipe - namely sucking out and disposing of the filthy black gel that blocks refrigeration condensate drains (a substance commonly known as 'elephant ...

  • 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 ...

  • 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 ...
