In recent years, the airflow hits the user and the wind direction and volume are controlled so as to increase the wind speed without lowering the indoor temperature.The increase in the wind speed hitting the user supplements the cooling sensation and saves energy without compromising comfort. To improve the performance, for example, a configuration described in an embodiment of JP-A-6-18072 is known. The configuration will be described below.

A four-hour timer has a four-hour timer. At a specified time, if the indoor set temperature is raised and the indoor temperature rises, the feeling of comfort is impaired as it is. For example, the temperature, humidity, and airflow proposed by Yaglow etc. are considered. Then, based on the sensible temperature when these change, etc., the wind speed of the blown airflow is increased to compensate for the increase in the indoor temperature, that is, by increasing the set temperature in the room and increasing the wind speed hitting the occupants. In other words, the air conditioning is performed at a temperature lower than the indoor temperature, and energy saving is achieved.

有していた。However, in the above configuration, in the first field, whether or not to perform this control is determined by the outside air temperature or a 24-hour timer.
There is a problem that energy saving cannot be achieved when the outside air temperature is equal to or less than a certain threshold value or when the outside air temperature is other than a specified time.

た。In the second field, for example, in a room with a large load, the temperature of the airflow blown out of the air conditioner, that is, the blowout temperature becomes very low, so that it is very low in the target direction of the wind direction control. The temperature distribution in the room becomes large, for example, in a temperature region. That is, since the temperature to be controlled is the indoor temperature, regardless of the blow-out temperature, if the wind direction is directed to the user or the wind speed is increased even if the indoor temperature is simply increased or the rotational speed of the compressor is reduced, the blow-out temperature is increased. Depending on the user, there is a problem that the user feels a cool wind feeling, becomes very uncomfortable, and impairs comfort.

決定する。The operation of the above configuration will be described below. As shown in Table 3, when the room temperature (Ta) is significantly higher than the set room temperature (Tset), a higher absolute value is determined in advance to lower the room temperature quickly. At this time, for example, when the load on the room is high, it is desired to determine the frequency for each load on the room in order to shorten the time for lowering the room temperature. Therefore, the outside temperature is used as one means for estimating the load on the room, and the frequency is determined according to the outside temperature. For example, "when the value obtained by subtracting the room temperature from the set room temperature is less than -3.5 ° C, the outside air temperature becomes 34.0 ° C.
110 ° C if lower than 0 ° C, 34.0 ° C or higher and 36.0 ° C
120Hz when less than, 130H when more than 36.0 ° C
z, and the value obtained by subtracting the room temperature from the set room temperature is-
When the temperature is between 3.5 ° C. and less than −3.0 ° C., the outside air temperature is 34.0
70 ° C when the temperature is lower than 0 ° C, 80 Hz when the temperature is 34.0 ° C or higher and lower than 36.0 ° C, 90 Hz when the temperature is 36.0 ° C or higher, and the value obtained by subtracting the indoor temperature from the set indoor temperature is −3.0 ° C.
When the outside air temperature is less than 34.0 ° C., the frequency is 30 Hz when the temperature is less than −2.0 ° C., 40 Hz when the temperature is 34.0 ° C. or more and less than 36.0 ° C., and 50 Hz when the temperature is 36.0 ° C. or more. ” , The frequency is determined from the difference between the set room temperature and the room temperature and the outside air temperature. When the difference between the set room temperature and the room temperature is less than 2.0 ° C., it is determined in the same manner as the frequency determination means 18 described in the first embodiment.
