The invention provides an air conditioner and a control method, the air conditioner comprises a compressor and a control element, the control element controls the compressor to work in a preset frequency range, and meanwhile the control element controls the proportion of the primary return air volume, the secondary return air volume and the fresh air volume of the air conditioner according to the external real-time temperature TW1 and the set temperature T1 of an area to be subjected to temperature adjustment. And the compressor works at the rated frequency or within a small frequency range, so that the technical problem of high failure rate of the compressor caused by frequent start and stop of a fixed-frequency air conditioner and large frequency fluctuation range of a variable-frequency air conditioner is solved, the failure rate and maintenance cost of the compressor are reduced, and the service life of the compressor is prolonged. And meanwhile, the air quality and comfort of the to-be-regulated area are improved.
Description
technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner and a control method. Background technique [0002] At present, air conditioners use fixed-frequency or variable-frequency compressors. The speed of the fixed-frequency compressor is basically unchanged, and the indoor temperature is adjusted by continuously starting and stopping the compressor; the variable-frequency compressor uses the frequency converter to change the power supply frequency to adjust the compressor speed to adjust the indoor temperature. , to achieve stepless adjustment. Due to the frequent start and stop of fixed frequency compressors, the service life of the compressor is greatly affected. At the same time, its adjustment response speed is generally slow, and the indoor ambient temperature and humidity often fluctuate greatly, and the comfort level is not high. The variable frequency compressor adjusts the indoor temp...
