REFRIGERANT COOLING AND LUBRICATION SYSTEM WITH REFRIGERANT VAPOR VENT LINE

摘要

Generally, apparatuses, systems, and methods are described to vent refrigerant vapor from the refrigerant pump line using a vent line, such as during priming of the pump and/or during a startup of the compressor, directed to a relatively reduced volute casing mass of the refrigerant pump, and/or directed to returning refrigerant to an economizer or chiller component other than the condenser.
