Oil separator

A method comprising:

• removing heat from a refrigerant using a high side heat exchanger;
• removing heat from a first space proximate to a load using the refrigerant;
• compressing the refrigerant from the first load using a compressor;
• receiving the refrigerant from the compressor using a horizontal oil separator comprising:
• a centrifugal chamber;
• and
• a horizontal body comprising a first side, a second side, a third side, a fourth side, and a fifth side, wherein:
• an inlet is coupled to the fifth side;
• a collector is coupled to the second side;
• a metal plate is coupled to the second side and the fourth side, the metal plate defining a plurality of apertures, the metal plate configured to allow the refrigerant to flow through the plurality of apertures, each aperture of the plurality of apertures having a diameter greater than a diameter of the inlet;
• a second filter comprising a mesh is coupled to the second side and the fourth side;
• an outlet is coupled to the third side;
• and
• rotating the refrigerant using the centrifugal chamber, wherein rotating the refrigerant separates an oil from the refrigerant;
• separating additional oil from the refrigerant using the metal plate;
• separating additional oil from the refrigerant using the second filter;
• collecting the oil separated in the centrifugal chamber and the additional oil using the collector;
• discharging the refrigerant to the high side heat exchanger using the outlet.
