Embodiment Construction
[0054] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0055] This embodiment provides a compressor lower limit frequency control method, including:
[0056] The operating parameters of the air conditioner are detected, and the minimum operating frequency of the compressor is adjusted according to the operating parameters, wherein the operating parameters include the phase current of the compressor.
[0057]Wherein, the operating parameters are parameters that can reflect the operating conditions of the compressor, so that the current operating conditions of the compressor can be judged according to the operating parameters. In this embodiment, if it is judged according to the operating parameters that the compressor is under a non-heavy load condition, the minimum operating frequency of the c...
