1. A scroll compressor comprising:
an orbiting scroll coupled to a rotating shaft and including an orbiting wrap, the orbiting wrap being disposed at an orbiting end plate and configured to orbit;
a fixed scroll including a fixed wrap disposed at a fixed end plate, the fixed wrap being configured to engage the orbiting wrap and define a compression chamber together with the orbiting wrap; and
a refrigerant accommodating groove defined at at least one of (i) a side surface of the fixed wrap defining the compression chamber or (ii) a side surface of the orbiting wrap,
wherein the compression chamber comprises a first compression chamber defined at an inner surface of the fixed wrap and a second compression chamber defined at an outer surface of the fixed wrap,
wherein the fixed end plate defines a first discharge port configured to discharge refrigerant in the first compression chamber and a second discharge port configured to discharge refrigerant in the second compression chamber, and
wherein the refrigerant accommodating groove is provided between the first discharge port and the second discharge port along a direction in which the fixed wrap extends.
 
13. A scroll compressor comprising:
an orbiting scroll coupled to a rotating shaft and including an orbiting wrap, the orbiting wrap being disposed at an orbiting end plate and configured to orbit;
a fixed scroll including a fixed wrap disposed at a fixed end plate, the fixed wrap being configured to engage the orbiting wrap and define a compression chamber together with the orbiting wrap; and
a refrigerant accommodating groove defined at at least one of (i) a side surface of the fixed wrap defining the compression chamber or (ii) a side surface of the orbiting wrap,
wherein the compression chamber comprises a first compression chamber defined at an inner surface of the fixed wrap and a second compression chamber defined at an outer surface of the fixed wrap,
wherein the fixed end plate defines a first discharge port configured to discharge refrigerant in the first compression chamber and a second discharge port configured to discharge refrigerant in the second compression chamber, and
wherein an auxiliary discharge port is provided between the first discharge port and the second discharge port and inserted through the fixed end plate.
