ABSTRACT:
In the air conditioning control apparatus of the present invention, the frequency determining means determines not only an operation frequency for the compressor depending on the load determined based on the detected room temperature and the set room temperature, but also an upper limit for the compressor operation frequency based on the air flow rate of the outlet air from the upper and lower outlet ports of the indoor unit and the successive operation time of the compressor. As a result, even if the compressor carriers out cooling operation under too great of a load, the temperature of the air blown off from the upper outlet port of the indoor unit is prevented from dropping down to less than a certain value, thereby eliminating economically the problem wherein dew is produced on the outer surface of the ceiling plate and so on.
