Scroll compressor and air conditioner including the same

摘要

The scroll compressor includes a fixed scroll including a first wrap, an orbiting scroll disposed to have a phase difference with respect to the fixed scroll, the orbiting scroll including a second wrap defining a compression chamber together with the first wrap, a suction part to receive a refrigerant into the compressor chamber, a driving shaft to transmit a rotation force to the orbiting scroll, a first injection part disposed in one position of the fixed scroll to introduce a refrigerant into the compression chamber, and a second injection part disposed in another position of the fixed scroll to introduce a refrigerant into the compression chamber, where the second wrap is disposed on the orbiting scroll such that the first injection part is opened to introduce the second refrigerant before the receipt of the first refrigerant through the suction part is completed during the orbiting of the orbiting scroll.

1. A scroll compressor comprising:
a fixed scroll comprising a first wrap; an orbiting scroll disposed to have a phase difference with respect to the fixed scroll, the orbiting scroll comprising a second wrap defining a compression chamber together with the first wrap; a suction part to receive a first refrigerant into the compressor chamber; a driving shaft to transmit a rotation force to the orbiting scroll; a first injection part disposed in one position of the fixed scroll to introduce a second refrigerant into the compression chamber; and a second injection part disposed in another position of the fixed scroll to introduce a third refrigerant into the compression chamber, wherein the second wrap is disposed on the orbiting scroll such that the first injection part is opened to introduce the second refrigerant before the receipt of the first refrigerant through the suction part is completed during the orbiting of the orbiting scroll, wherein the opening of the first injection part allows the second refrigerant injected through the first injection part to be mixed with a first refrigerant compressed in a first stage of the compression chamber and the second wrap is moved such that the mixed first and second refrigerants re compressed in a second stage of the compression chamber.
