Air conditioner and method of controlling the same
First Claim
1. An air conditioner, comprising:
- a compressor which rotates in opposing directions;
a drive unit which rotates the compressor in a first or second direction;
a start determining unit which determines whether the compressor has started to rotate in the first direction; and
a control unit which operates the drive unit so as to rotate the compressor in the second direction opposite to the first direction, and then re-start the compressor in the first direction, when the compressor has failed to start.

Abstract
An air conditioner has a variable capacity rotary compressor, which allows the compressor to be smoothly re-started, thus increasing start reliability of the compressor. The air conditioner includes a compressor rotated in opposite directions. A drive unit rotates the compressor in a forward or reverse direction. A start determining unit determines whether the compressor has started to rotate in a forward direction or not. A control unit operates the drive unit so as to rotate the compressor in a direction opposite to the forward direction, and then re- start the compressor in the forward direction, when the compressor has failed to start. The air conditioner and a method of controlling the air conditioner allow the compressor to be smoothly and rapidly re-started even when the compressor has failed to re-start, thus increasing start reliability, and shortening a time required to re-start the compressor.

4. A method of controlling an air conditioner, the air conditioner having a compressor which is rotatable in opposing directions, the method comprising:
-
starting the compressor to rotate the compressor in a first direction;
determining whether the compressor has started to rotate in the first direction; and
re-starting the compressor in the first direction after rotating the compressor in a second direction, when the compressor has failed to start. - View Dependent Claims (5, 6, 24)
