Air conditioner

An air conditioner comprising:

• a housing having an inlet port and having an opening;
• a heat exchanger configured to exchange heat with air sucked in through the inlet port;
• a blower configured to circulate air into or out of the housing;
• and
• a discharge unit having an outer circumferential surface and configured to be rotatable relative to the housing, the discharge unit having a first outlet port formed in a portion of the outer circumferential surface to discharge the heat-exchanged air and a second outlet port formed in another portion of the outer circumferential surface to discharge the heat-exchanged air at different speed from the air discharged from the first outlet port, the discharge unit being rotatable to a first position at which the first outlet port is aligned to discharge air through the housing opening, and being rotatable to a second position at which the second outlet port is aligned to discharge air through the housing opening.
