PURPOSE:To perform the optimum air conditioning even when the temperature change is slow like in an intermediate stage when an operation signal from a temperature sensing element by causing to perform a forced heating operation for a certain duration in a certain interval so as to forcibly circulating the air in the room. CONSTITUTION:When the operation is started under a condition where the room temperature Ta is Ta<T100, a room fan 16, a compressor 20, a outside fan 18 and an electric heater 21 are energized, and the compressor 20 is operated at 100% of its capacity. When the room temperature Ta becomes higher than a temperature T80 since, the compressor 20 operates at 80% of its capacity. When the room temperature Ta is further lowered to temperature T0, the compressor 20 and outside fan 18 are turned OFF, and only the room fan 16 is operated. Then, a 9min timer is started. If the air conditioning load is small at this time and the temperature reduction is so slow that the room temperature Ta is still above the set temperature Ts after the 9min timer has timed up, a 3min timer starts counting after the 9min, and the compressor 20, outside fan 18 and room fan 16 are energized to start the operation. |
