Scroll compressor and air conditioner having the same

A scroll compressor, comprising:

• a casing defining an inner space therein that is communicably coupled to a discharge pipe configured to be connected to an inlet side of a condenser of a cooling cycle device;
• a drive motor provided in the inner space of the casing;
• a rotation shaft coupled to the drive motor;
• a frame provided at a lower side of the drive motor;
• a first scroll provided at a lower side of the frame, with a first side of the first scroll formed with a first wrap;
• and
• a second scroll formed with a second wrap configured to engage with the first wrap, with the rotation shaft eccentrically coupled to the second wrap and configured to, as the rotation shaft rotates, move the second wrap along an orbital motion around the shaft with respect to a fixed position of the first wrap to form a compression chamber between the first scroll and the second scroll, with the compression chamber being connected to an outlet side of an evaporator of the cooling cycle,
• wherein the compression chamber is configured to be communicable, through an opening in the first scroll, with an injection unit having a first end that is configured to branch from a refrigerant pipe arranged between the condenser and the evaporator.
