摘要： A heat exchanger system is provided. The heat exchanger system includes a vapor-compression circuit. The vapor compression circuit includes a compressor (11), an expansion valve (12), a condenser (13) fluidly interposed between the compressor and the expansion valve and an evaporator (14) fluidly interposed between the expansion valve and the compressor. The condenser includes a de-superheating segment (20) and a condensing segment (30). The condensing segment is receptive of a first liquid downstream from the de-superheating segment. The condensing and de-superheating segments are receptive of a second liquid in parallel. Flows of the second liquid into the de-superheating segment are controllable by a control valve (70) based on the temperature of flows of the second liquid exiting the de-superheating segment measured by a temperature sensor (60).

摘要： A compressor arrangement includes two or more compressors (16a, 16b) arranged in a fluidly parallel configuration and a lubricant sump (38) containing a volume of lubricant operably connected to the two or more compressors. A lubricant sump pressure (P) is greater than a lubricant cavity pressure of each compressor (Pa, Pb, Pc) of the two or more compressors at all operating conditions of the two or more compressors. An equilibrium lubricant line (40) connects the lubricant sump to the two or more compressors to convey lubricant from the lubricant sump to a lubricant cavity (42) of each compressor of the two or more compressors.
