Definitions
- the present invention relates to an air conditioner and an air conditioner that performs heating with a heater.
- a heater is provided as an auxiliary heater. Heating by the heater is performed simultaneously with the heating operation by the refrigeration cycle of the air conditioner at a low outside air temperature. By operating the heater, it is possible to make up for the lack of heating capacity of the air conditioner.
- the heater operates at the same time, but the heater is switched on and off so that the heating capacity is not more than necessary. That is, while the air conditioner is performing the heating operation, after the room temperature rises and reaches the set temperature, the compressor of the air conditioner is stopped and the heater is also turned off. When the room temperature decreases, the heater operates together with the air conditioner. When the heater turns on, the room temperature rises too much. For this reason, the compressor and heater of the air conditioner are frequently turned on and off, consuming electric power unnecessarily and not realizing energy saving.
- an object of the present invention is to provide an air conditioner that can perform comfortable heating by supplementing the heating capacity of the air conditioner by operating the heater according to the situation.

- the room temperature can be set to the set temperature in a short time, and energy saving can be achieved.
- the air conditioner During heating operation of the air conditioner, it is preferable to turn off the heater before the room temperature reaches the set temperature. If it does in this way, after turning off a heater, it will be only heating by an air conditioner, and it can heat, suppressing change of room temperature.
- the stop temperature when the heater is turned off during the heating operation is set according to the outside air temperature, and the difference between the set temperature and the stop temperature is preferably smaller as the outside air temperature is lower. In this way, the lower the outside air temperature is, the more the heater can compensate for the low heating capacity of the air conditioner and the room temperature can be raised faster.
- the air conditioner performs the heating operation with the compressor rotating speed within the high efficiency range or the maximum rotating speed. In this way, the heating capacity of the air conditioner can be maximized, and the room temperature can be quickly raised.
- the air conditioner stops the heating operation and performs the air blowing operation so that the heater operates.
- the second predetermined temperature is lower than the first predetermined temperature. In this way, when the outside air temperature becomes lower than the predetermined temperature, the air conditioner does not perform the heating operation in order to protect the air conditioner. Therefore, only the heater operates, and heating is performed instead.
- the heater in addition to heating by an air conditioner, the heater can be used effectively, so that the room temperature can be raised quickly. Thereby, the power consumption at the time of heating can be reduced.

Claims (5)
- 圧縮機を駆動して空調運転を行う空気調和機と、空気調和機に連動して作動する加熱機とから構成される空気調和装置であって、外気温が第1の所定温度未満のとき、加熱機による暖房をメイン暖房として、空気調和機が暖房運転を行い、外気温が第1の所定温度以上のとき、空気調和機の暖房運転をメイン暖房として、加熱機による暖房を補助暖房とすることを特徴とする空気調和装置。
- 空気調和機の暖房運転中、室温が設定温度に達する前に加熱機がオフすることを特徴とする請求項1記載の空気調和装置。
- 暖房運転中に加熱機がオフするときの停止温度は、外気温に応じて設定され、設定温度と停止温度との差は、外気温が低いほど小さいことを特徴とする請求項2記載の空気調和装置。
- 空気調和機は、圧縮機の回転数を高効率範囲あるいは最大回転数にして暖房運転を行うことを特徴とする請求項1~3のいずれかに記載の空気調和装置。
- 外気温が第2の所定温度より低くなったとき、空気調和機は暖房運転を停止して、送風運転を行い、加熱機が作動することを特徴とする請求項1~4のいずれかに記載の空気調和装置。
