AIR CONDITIONER AND METHOD OF CONTROLLING THE SAME
First Claim
1. An air conditioner comprising:
- a compressor;
a heat exchanger performing heat exchange between a refrigerant and air through movement of the air;
a frost formation detector provided in the heat exchanger for detecting a frost formation degree in the heat exchanger to output a detection signal; and
a controller configured to compute a frost formation level due to freezing in the heat exchanger according to the detection signal inputted from the frost formation detector, and to perform a defrosting operation according to the frost formation level.

Abstract
An air conditioner and a method for controlling the same for securing reliability and increasing efficiency are provided. The air conditioner and the method of controlling the same detect freezing occurring in the heat exchanger of the outdoor unit, determine a time of the defrosting operation according to a freezing degree such that the defrosting operation is performed, thereby preventing cooling/heating operation efficiency and capability due to a frequent defrosting operation from being deteriorated. The air conditioner and the method of controlling the same according to the present invention provide comfort of a predetermined level to the user to solve deterioration of convenience, and remove freezing due to a defrosting operation to thereby improve efficiency during cooling/heating operations.
