Abstract:
A refrigeration system includes first and second compressors and an oil separator. The oil separator includes an inlet for receiving refrigerant and oil from the first compressor, a refrigerant outlet, and an oil outlet. The oil separator separates the oil from the refrigerant. A portion of the oil separator below a horizontal plane intersecting the refrigerant outlet collects separated oil and has a volume equal to a first compressor oil supply. The first compressor oil supply is greater than or equal to 100% and less than or equal to 250% of a first compressor initial oil charge. The first compressor receives oil from the oil outlet when an amount of oil in the portion is less than or equal to the first compressor oil supply. The second compressor receives oil from the refrigerant outlet when the amount of oil in the portion is greater than the first compressor oil supply.

Claim (Index 1):
A refrigeration system comprising:\n at least one first compressor fluidly connected to a first suction line and a first discharge line; at least one second compressor fluidly connected to a second suction line and a second discharge line, the second suction line being fluidly connected to the first discharge line; a condenser operable to receive refrigerant from the at least one second compressor; a first evaporator operable to receive refrigerant from the condenser and discharge refrigerant to the first suction line; a second evaporator operable to receive refrigerant from the condenser and discharge refrigerant to the second suction line; and an first oil separator comprising a first inlet fluidly connected to the first discharge line, a first refrigerant outlet fluidly connected the second suction line, a first oil outlet fluidly connected to a first sump of the at least one first compressor, a first horizontal plane intersecting the first refrigerant outlet, wherein:\n the first oil separator is adapted to receive refrigerant and oil from the at least one first compressor through the first inlet and separate at least a portion of the oil from the refrigerant; \n a first portion of the first oil separator below the first horizontal plane is configured to collect separated oil; \n the first portion is sized to have a volume equal to a first compressor oil supply, the first compressor oil supply being greater than or equal to about 100% of a first compressor initial oil charge and less than or equal to about 250% of the first compressor initial oil charge; \n the at least one first compressor is configured to receive oil from the first oil outlet when an amount of oil in the first portion is less than or equal to the first compressor oil supply; and \n the at least one second compressor is configured to receive oil from the first refrigerant outlet when the amount of oil in the first portion is greater than the first compressor oil supply.
