Flow and separation of the oil from compressor discharge to external separator
Oil is essential for most of the refrigerant compressors, but oil circulating in the refrigeration or air conditioning systems has a side effect on the heat transfer and total efficiency. Oil separator is an important component to reduce the amount of oil circulating in the system and to keep the …

A computational and experimental investigation into the performance of industrial refrigeration helical oil separators
An oil separator is a key component in an industrial refrigeration system as it prevents the compressor discharge oil creating a liquid film on the internal walls of the heat exchangers which leads to a reduction in efficiency of the system and increased operating costs. The Henry Technologies …

Mist to annular flow development quantified by novel video analysis methods
… transport properties, specifically refrigerant-oil flows. While the primary purpose of the model is to predict the development of liquid from the mist to annular regimes, additional models were able to predict the development of film speed, thickness, and wavelength. Furthermore, the …

Oil flow from compressor valve to discharge tube
Oil existence is important for compressor operation because it provides lubrication, cooling and sealing. But the discharge process of the compressor inevitably entrains some oil in the refrigerant vapor, which makes oil leave compressor and circulate in the system. For better heat transfer and …

An air-to-air heat pump
… heat pumps is the defrosting of the outside coil. Several methods were outlined but the best solution for defrosting the coil would depend upon the conditions pertaining to each unit. Several suggestions were outlined where research is needed for the proper utilization of air as a heat source …

Experimental and modeling study of lubricant effect on refrigerant distribution in microchannel evaporators
… automobile air conditioning systems where oil separator is less commonly used, the lubricant pumped out of the compressor is mixed with refrigerant and travels throughout the system. In this study, lubricant effect on refrigerant distribution in microchannel evaporators is investigated and …
