た。FIG. 3 shows the control method and room temperature when the load on the room is relatively large and the outside air temperature is relatively low. When the outside air temperature is relatively low and the load is large, the maximum capacity operation is performed at room temperature because the room temperature does not reach the set temperature even after the predetermined operation time T 1, and the maximum operation is canceled after T 1 hour. Was difficult to reach the set temperature.

るものである。In the prior art, as described in the previous section, when the load on the room is large and the outside air temperature is relatively low, the room temperature is less likely to reach the set temperature.
The present invention intends to provide an air conditioner that quickly sets room temperature to a set temperature even when such a load is large.

FIG. 4 is a control flowchart of one embodiment of the present invention. Description will be given using FIG. When the main operation is turned on at the start of operation, the outside temperature is detected by the outside temperature detecting thermistor 8 installed in the outdoor unit. The outside air temperature determines the time for maximum capacity operation (operation in which at least one of the compressor, the indoor air blower, and the outdoor air blower has the maximum output). 5 and 6
Shows an example of a table for determining the maximum capacity operation. Figure 5
Is an example in the case of heating operation, and the lower the outside air temperature is, the longer the maximum capacity operation time is. FIG. 6 shows the case of the cooling operation, and the higher the outside air temperature, the longer the maximum capacity operation time. This is because when the outside air temperature is low during heating and when the outside air temperature is high during cooling, the room cooling and heating loads increase, and a larger capacity is required to bring the room temperature to the set temperature. . As a method of determining such a maximum capacity operation time, there is a method of making a table as shown in FIGS. 5 and 6, but a method of storing it in a microcomputer as an arithmetic expression of a function.
