Abstract

When the outside air temperature is low, an air conditioner 1 performs a heating operation while a heating unit 2 performs a main heating operation. When the outside air temperature is high, the air conditioner 1 performs a main heating operation, and the heating unit 2 performs an auxiliary heating operation. While the air conditioner 1 performs a heating operation, the heating unit 2 is turned off before the room temperature reaches a set temperature. That is, the heating unit 2 is turned on for a longer time as the outside air temperature becomes lower. In this way, the heating unit 2 is operated under the situation to thereby supplement the heating capacity of the air conditioner 1, so that comfortable heating is performed.

Claims

1-5. -5. (canceled)

6. An air conditioning apparatus configured by an air conditioner performing an air conditioning operation by driving a compressor, and a heating device operating in conjunction with the air conditioner, wherein:

when an outside air temperature is lower than a first predetermined temperature, the air conditioner performs a heating operation while the heating device performs a main heating operation; and

when the outside air temperature is not lower than the first predetermined temperature, the air conditioner performs a main heating operation, and the heating device performs an auxiliary heating operation.

7. The air conditioning apparatus according to claim 6, wherein, during the heating operation of the air conditioner, the heating device is turned off before the room temperature reaches a set temperature.

8. The air conditioning apparatus according to claim 7, wherein a stop temperature, at which the heating device is turned off during a heating operation, is set according to the outside air temperature, and a difference between the set temperature and the stop temperature decreases as the outside air temperature decreases.

9. The air conditioning apparatus according to claim 6, wherein the air conditioner performs a heating operation so that a number of revolutions of the compressor is in a high efficiency range or at a maximum rotational speed.

10. The air conditioning apparatus according to claim 7, wherein the air conditioner performs a heating operation so that a number of revolutions of the compressor is in a high efficiency range or at a maximum rotational speed.

11. The air conditioning apparatus according to claim 8, wherein the air conditioner performs a heating operation so that a number of revolutions of the compressor is in a high efficiency range or at a maximum rotational speed.

12. The air conditioning apparatus according to claim 6, wherein, when the outside air temperature is lower than a second predetermined temperature, the air conditioner stops a heating operation to perform a blowing operation, and the heating device operates.

13. The air conditioning apparatus according to claim 7, wherein, when the outside air temperature is lower than a second predetermined temperature, the air conditioner stops a heating operation to perform a blowing operation, and the heating device operates.

14. The air conditioning apparatus according to claim 8, wherein, when the outside air temperature is lower than a second predetermined temperature, the air conditioner stops a heating operation to perform a blowing operation, and the heating device operates.

15. The air conditioning apparatus according to claim 9, wherein, when the outside air temperature is lower than a second predetermined temperature, the air conditioner stops a heating operation to perform a blowing operation, and the heating device operates.

16. The air conditioning apparatus according to claim 10, wherein, when the outside air temperature is lower than a second predetermined temperature, the air conditioner stops a heating operation to perform a blowing operation, and the heating device operates.

17. The air conditioning apparatus according to claim 11, wherein, when the outside air temperature is lower than a second predetermined temperature, the air conditioner stops a heating operation to perform a blowing operation, and the heating device operates.
