Claim Text:
1. A method of controlling an air conditioning device, the method comprising: performing a first air conditioning step at a first operation temperature for a first duration time; performing a second air conditioning step at a second operation temperature for a second duration time after the first air conditioning step has been performed, wherein the second operation temperature is higher than the first operation temperature; alternately repeating the first air conditioning step and the second air conditioning step multiple times to provide heating or cooling to a room; decreasing the first duration time of the first air conditioning step and then increasing the first duration time as the first air conditioning step is repeated multiple times; and increasing the second duration time of the second air conditioning step and then decreasing the second duration time as the second air conditioning step is repeated multiple times, wherein alternately repeating the first air conditioning step and the second air conditioning step multiple times includes increasing the second operation temperature of the second air conditioning step to a third operation temperature higher than the second operation temperature after increasing the first operation temperature of the first air conditioning step to the second operation temperature and performing the first air conditioning step at the second operation temperature and the second air conditioning step at the third operation temperature multiple times in a repetitive operation, without providing the first operation temperature, after alternately repeating the first air conditioning step at the first operation temperature and the second air conditioning step at the second operation temperature multiple times.
