PROBLEM TO BE SOLVED: To properly control temperature of blowoff air in response to an air conditioning environment by controlling the speed of a compressor based upon set temperature determined by a room temperature set means and room temperature detected by an indoor sensor. SOLUTION: Upon heating operation, room temperature set means 113 employs as an initial value set temperature Ts of a manual room temperature set value 114, and determines set temperature Tsc based upon detected room temperature Ta and indoor heat exchanger temperature Tc. Selection means 115 selects the set temperature Tsc of the room temperature set means 113 to apply it to compressor speed control means 116, and it select the set temperature Ts only when an operation instruction due to the set temperature Ts is given from the manual room temperature setting unit 114 to apply it to the compressor speed control means 116. The compressor speed control means 116 controls the number of revolutions of the compressor 101 also taking into consideration a difference between the set temperature Tsc or Ts and the room temperature Ta detected by the room temperature sensor 111. |
