感を与えるだけではｌく、快適な温調ができなかった。Problems to be Solved by the Invention However, in the conventional configuration described above, when the indoor temperature is detected by the air temperature sensor installed in the indoor heat exchanger suction part during heating operation, it is difficult to detect when the indoor temperature distribution is poor or when the indoor temperature distribution is poor. When the indoor unit is installed high on the ceiling, there will be a difference between the temperature around the user and the detected air temperature, which will not only give the user a feeling of cold air but also make it difficult to control the temperature comfortably. There wasn't.

と言う）という課題を有していた。Additionally, when the outside temperature is high and the indoor air temperature is detected by the temperature sensor installed on the remote control, the temperature of the air sucked into the indoor heat exchanger will be higher than the detected temperature, and the discharge pressure of the compressor will rise. . At this time, the discharge pressure of the compressor exceeded the pressure switch setting to protect the system, resulting in the problem of forcibly stopping the air conditioner (hereinafter referred to as "high pressure cut").

The purpose is to provide

ある。Means for Solving the Problems To achieve this object, the air conditioner of the present invention detects the indoor temperature when the outside air temperature is above a predetermined temperature (for example, 6
°C or higher), the indoor temperature is selected as the temperature detected by the first room temperature sensor installed on the suction side of the indoor heat exchanger, and if the outside temperature is lower than a predetermined temperature (for example, lower than 6 °C),
The device includes a control device that selects the indoor temperature to the temperature detected by a second room temperature sensor that detects the temperature around the remote controller.

Even when the temperature is higher, by setting the indoor temperature to the air temperature around the user, we provide a comfortable environment without giving the user a feeling of cold air. It is possible to prevent forced stoppage of the operation of the air conditioner.
