A refrigeration assembly includes a receiver tank, a heat exchanger, a first piping assembly, and a second piping assembly. The receiver tank has a fluid outlet and a fluid inlet that receives a working fluid. The heat exchanger is disposed within the receiver tank. The heat exchanger has coiled tubing that is fluidly coupled to the fluid inlet and to the fluid outlet. The first piping assembly is disposed between and is fluidly coupled to the fluid inlet and the coiled tubing. The first piping assembly has a first double riser and a first P-trap. The second piping assembly is disposed between and is fluidly coupled to the fluid outlet and the coiled tubing. The second piping assembly includes a second double riser and a second P-trap.

Oil management in refrigeration systems

Various embodiments disclosed herein related to a multistage oil separator. The oil separator includes a housing having a nozzle and defining an internal space and an oil outlet; a body disposed within the internal space, the body including a mixed fluid inlet configured to receive a coolant and oil mixture and a nozzle that receives at least a portion of the coolant and oil mixture from the mixed fluid inlet and discharges coolant and oil into the internal space of the housing; and, a wall disposed proximate to the nozzle of the body, wherein at least a portion of the discharged coolant and oil impacts the wall to direct the at least the portion of coolant and oil towards the nozzle of the housing. The oil separator functions to separate the coolant from the oil discharged from a compressor in a cooling system.
