温度変化による快適性の低下を防止できる。As described above, the cooling operation, the heating operation, and the air blowing operation are automatically controlled based on the difference between the set room temperature T0 and the room temperature t. In the heating operation, the compression function becomes smaller as the room temperature becomes lower than the set room temperature. Compressor that increases the compression capacity when the room temperature is higher than the set room temperature, decreases the compression capacity when the room temperature is higher than the set room temperature, and decreases the compression function when the room temperature is lower than the set room temperature during cooling operation. When the mode is switched from the heating mode to the cooling mode, the cooling start temperature T2 which is two steps higher than the set temperature T0 is performed.
Since the air-conditioning load is such that the cooling operation is started and the heating is switched from the heating, the room temperature rapidly drops. However, the conventional set room temperature T0 until the compressor stop number X reaches the predetermined number X1.
Is set to a constant temperature A higher, the capacity control of the compressor 6a works early on the decrease in the room temperature, the capacity can be reduced, and the room temperature does not cause a sudden decrease in the room temperature. Can be prevented from lowering.

の低下を防止できる。Similarly, when the mode is switched from the cooling mode to the heating mode, the number X of times the compressor is stopped is set to the predetermined number X2.
The conventional set room temperature T0 is kept at a constant temperature B lower until the temperature of the compressor 6a is reached, so that the capacity control of the compressor 6a works early in response to the rise of the room temperature, the capacity can be reduced, and the room temperature rises sharply. Therefore, it is possible to prevent a decrease in comfort due to a sudden temperature change.

を防止できる。As described above, the cooling operation, the heating operation, and the blowing operation are automatically controlled based on the difference between the set room temperature T0 and the room temperature t. In the heating operation, the compression function becomes smaller as the room temperature becomes lower than the set room temperature. Compressor that increases the compression capacity when the room temperature is higher than the set room temperature, decreases the compression capacity when the room temperature is higher than the set room temperature, and decreases the compression function when the room temperature is lower than the set room temperature during cooling operation. When the mode is switched from the heating mode to the cooling mode, the cooling start temperature T2 which is two steps higher than the set temperature T0 is performed.
Since the air-conditioning load is such that the cooling operation is started and the heating is switched from the heating, the room temperature rapidly decreases. However, the conventional set room temperature T0 is increased to a constant temperature A higher, and the original temperature gradually increases with the elapsed time of the timer 33. By returning the temperature to the set room temperature T0, the capacity control of the compressor 6a works earlier with respect to the lowering of the room temperature, and the capacity can be reduced. Drop can be prevented.

By gradually returning the temperature to the original set room temperature T0 with the elapsed time of the timer 33, the capacity control of the compressor 6a works early in response to the rise of the room temperature, and the capacity can be reduced, and the room temperature rises rapidly. Therefore, it is possible to prevent a decrease in comfort due to a rapid change in temperature without causing any trouble.

The lower the temperature, the higher the compression function power, the lower the room temperature is higher than the set room temperature, the lower the compression function power. Performs compressor capacity control to reduce the functional power, and then switches from the heating mode to the cooling mode, the cooling operation starts from the cooling start temperature two steps higher than the set temperature, and the air conditioning load is such that it switches from the heating. Therefore, the room temperature drops sharply, but the conventional set room temperature is raised to a certain temperature higher until the number of times the compressor stops reaches a predetermined number, so that the compressor can be cooled earlier than the room temperature decreases. Force acts control, since gradually decreases without abrupt room temperature reduction, there is no discomfort due to rapid change in room temperature, there is an effect that it is possible to maintain a comfortable indoor environment.
