Wherein F is 1 Is a constant greater than zero.
Along with the development of energy-saving and environment-friendly technology, the energy-saving requirement of people on the air conditioner is higher, the simple control of the operation frequency of the variable-frequency air conditioner in the prior art cannot meet the requirement of users, when the operation frequency of the variable-frequency air conditioner is adjusted, consideration of energy-saving effect is lacking, when the compressor is in a high-frequency state, the energy efficiency ratio is lower, and when the compressor is operated in a long-time high-frequency state, the reliability of the compressor is influenced, and the service life of the compressor is shortened.
The energy consumption of the compressor accounts for most of the energy consumption of the whole air conditioner, the energy efficiency ratio of the air conditioner can be greatly improved by reducing the energy consumption of the compressor, and the upper limit operation frequency of the compressor is limited to reduce the energy consumption because the energy efficiency ratio of the compressor operated at different frequencies is different, especially the energy efficiency ratio is lower during high-frequency operation. In addition, the scheme comprehensively considers the refrigerating requirement of the room where the air conditioner is located, so that the air conditioner can adjust the upper limit operating frequency of the compressor under the condition that the use experience of a user is not affected, thereby reducing the energy consumption of the compressor and improving the energy consumption ratio of the air conditioner.
Specifically, a first upper limit operating frequency F 1 The maximum frequency upper limit reference value is the highest frequency upper limit reference value which is qualified by condensation of the air conditioner under the high-humidity working condition.

Specifically, the indoor unit of the air conditioner is provided with a temperature sensor which can detect the temperature T of the inner ring Inner ring 。
It should be noted that, in the air conditioner performing the cooling mode, the indoor temperature difference Δt is calculated by Δt=t Inner ring -T Setting up The indoor temperature difference delta T represents the difference between the indoor temperature and the set temperature of the air conditioner, and the larger the indoor temperature difference delta T is, the higher the indoor temperature is, so that the user experience is poor; the smaller the indoor temperature difference deltat is, and the indoor temperature is not different from the set temperature, even lower than the set temperature, and the better the user experience is. When the indoor temperature difference deltat is large, the air conditioner is required to quickly reduce the indoor temperature to the set temperature, and the upper limit operating frequency of the air conditioner is not adjusted at this time, so that the air conditioner can quickly refrigerate. When the indoor temperature difference deltat is smaller, the indoor temperature is not greatly different from the set temperature, and the air conditioner is not required to quickly refrigerate at the moment, so that the upper limit operating frequency F of the air conditioner is adjusted at the moment Upper limit of To reduce the energy consumption of the compressor.
