  • the energy performance of a single screw compressor for natural gas liquefaction process effects of the lubricating oil flow rate
    International Journal of Energy Research, 2019
    Co-Authors: Yong Li, Yuanwei Lu, Yuting Wu, Bengt Sundén
    Abstract:

    An experimental test system including the oil circulation system and the gas circuit system has been designed and built to explore the effects of the lubricating oil flow rate on the performance of a single-screw compressor, used in a portable natural gas liquefaction process. Outlet Pressure, Outlet volumetric flow rate, volumetric efficiency, and specific power rate are the parameters for evaluation of the energy performance of the single-screw compressor. The experimental results indicate that the Outlet Pressure and Outlet volumetric flow rate can be effectively increased by increasing the flow rate of the lubricating oil at different rotational frequencies and that a certain amount of lubricant oil is helpful to improve the volumetric efficiency. In terms of the specific power rate, the optimum oil-gas ratios are 0.7%, 0.93%, and 1.79%, and the corresponding Outlet Pressures are 0.45, 0.45, and 0.48 MPa at the conditions of 50, 40, and 30 Hz, respectively.

  • thermodynamic analysis of transcritical co2 refrigeration cycle with an ejector
    Applied Thermal Engineering, 2011
    Co-Authors: Sun Fangtian, Ma Yitai
    Abstract:

    A comparative study on transcritical carbon dioxide refrigeration cycle with ejector and with throttling valve was performed by the first and second laws of thermodynamics in theory. The effects of the entrainment ratio of the ejector, heat rejection Pressure, Outlet temperature of gas cooler and evaporating temperature on the coefficient of performance (COP) and exergy loss were investigated in transcritical carbon dioxide refrigeration cycle with ejector and with throttling valve. It is found that ejector instead of throttling valve can reduce more 25% exergy loss and increase COP more 30%. In addition, critical entrainment ratio of the ejector, optimal heat rejection Pressure and critical Outlet temperature of gas cooler affects COP greatly for the transcritical carbon dioxide refrigerating cycle with ejector.
