Method for controlling frequency of compressor, device for controlling frequency of compressor and air conditioner

Abstract

The invention provides a method for controlling the frequency of a compressor, a device for controlling the frequency of the compressor and an air conditioner. The method for controlling the frequency of the compressor comprises the steps that after the air conditioner is started, if an initial set temperature is received, historical initial set temperatures in a time interval where the set moment of the initial set temperature is in are obtained, whether the initial set temperature is matched with the historical initial set temperatures or not is judged, and when a judging result is positive, the operation frequency of the compressor is controlled according to a received operation mode and historical temperature records in the time interval. According to the technical scheme, the air conditioner can have the self-learning capability, the frequency of the compressor of the air conditioner can be adjusted in real time according to the use habits of a user, so that the comfort degree experience of the user is improved, operation of the user is reduced, and the energy utilization efficiency is increased.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a compressor frequency control method, a compressor frequency control device and an air conditioner. Background technique [0002] At present, the setting parameters of air conditioners at the factory depend on national standards. For example, the cooling conditions mentioned in GB7725 are 35°C / 24°C outdoor and 27°C / 15°C indoors, that is, the air conditioner matches a specific refrigeration system for a specific working condition. , such as matching different refrigerant injection volumes, capillary tube lengths, and expansion valve openings for different working conditions. It will be different, and it is difficult to keep the temperature difference between the internal and external environment consistent with the national standard, and the user's usage habits at different times will also be different. [0003] However, in the existing air conditioner control m...

[0002] At present, the setting parameters of air conditioners at the factory depend on national standards. For example, the cooling conditions mentioned in GB7725 are 35°C/24°C outdoor and 27°C/15°C indoors, that is, the air conditioner matches a specific refrigeration system for a specific working condition. , such as matching different refrigerant injection volumes, capillary tube lengths, and expansion valve openings for different working conditions. It will be different, and it is difficult to keep the temperature difference between the internal and external environment consistent with the national standard, and the user's usage habits at different times will also be different.

[0003] However, in the existing air conditioner control methods, once the whole machine is debugge...
