Multi-compressor oil migration mitigation climate system

A climate system for conditioning air within a compartment of a vehicle, comprising:

• a refrigerant circuit;
• a first compressor fluidly coupled to the refrigerant circuit, where the first compressor includes a first compressor inlet and a first compressor outlet;
• a second compressor fluidly coupled to the refrigerant circuit, the second compressor including a second compressor inlet and a second compressor outlet;
• a first refrigerant-to-air heat exchanger fluidly coupled to the first compressor outlet and the second compressor outlet via a first set of one or more refrigerant lines, wherein the first refrigerant-to-air heat exchanger is thermally coupled to an exterior of the vehicle and forms part of the refrigerant circuit;
• a second refrigerant-to-air heat exchanger (i) fluidly coupled to the first refrigerant-to-air heat exchanger via a second set of one or more refrigerant lines and (ii) fluidly coupled to the first compressor inlet and the second compressor inlet via a third set of one or more refrigerant lines, wherein:
• the second refrigerant-to-air heat exchanger is thermally coupled to the compartment of the vehicle and forms part of the refrigerant circuit, and
• a first refrigerant line of the third set of one or more refrigerant lines includes a first section configured to cause any compressor oil mixed in the refrigerant to flow from a first lower elevation to a first higher elevation before flowing to the first compressor to restrict a flow of compressor oil to the first compressor when the first compressor is inactive;
• and
• a second refrigerant line of the third set of one or more refrigerant lines includes a second section configured to cause any compressor oil mixed in the refrigerant to flow from a second lower elevation to a second higher elevation before flowing to the second compressor to restrict a flow of compressor oil to the second compressor when the second compressor is inactive;
• and
• a controller communicatively coupled to the first and second compressors and including instructions that are configured to selectively activating and deactivating the first and second compressors.
