2. Description of the Related Art Conventionally, in controlling the indoor temperature of an air conditioner, the operating frequency of the compressor is calculated by fuzzy calculation from the difference between the indoor temperature and the set temperature and the change (rate of change) of the indoor temperature per unit time. The rotation speed of the machine is controlled, the cooling or heating capacity of the air conditioner is changed, and the room temperature is maintained at the set temperature. However, the fluctuation of the indoor temperature is also influenced by the outdoor temperature and the size of the room to be air-conditioned, and it is not possible to unambiguously control the rotation speed of the compressor from the difference between the indoor temperature and the set temperature and the rate of change of the indoor temperature. ,
There are cases where the temperature does not match the set temperature very quickly. For example, even if the difference between the room temperature and the set temperature and the rate of change of the room temperature are the same, it takes longer to reach the set temperature due to the outside air temperature, the size of the room to be air-conditioned, etc.
To meet the set temperature quickly, a slightly higher cooling or heating capacity, or a lower cooling or heating capacity may be required.
