Abstract

The invention discloses an air conditioner and a combined control method for a compressor in the air conditioner and an outdoor draught fan. The combined control method comprises the following steps that a user control instruction is received; a motor of the compressor is controlled according to the user control instruction so as to adjust the rotating speed of the motor of the compressor; the current rotating speed of the motor of the compressor is acquired, and the target rotating speed of a motor of the outdoor draught fan is worked out according to the current rotating speed of the motor of the compressor; and the motor of the outdoor draught fan is controlled according to the target rotating speed of the motor of the outdoor draught fan so that the rotating speed of the motor of the outdoor draught fan can be matched with the rotating speed of the motor of the compressor, and combined control of the compressor and the outdoor draught fan is achieved. The mismatching degree of the compressor and the outdoor draught fan is effectively decreased, and the energy efficiency of the air conditioner is ensured. In addition, the combined control method is simple and easy to achieve and has high universality and practicality.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a combined control method for a compressor and an outdoor fan in the air conditioner. Background technique [0002] Compared with fixed-speed air conditioners, inverter air conditioners have the advantages of energy saving and low noise, so they have won the trust of the majority of users. [0003] At present, most air conditioner manufacturers at home and abroad use the control method of built-in fan drive + compressor drive + dual chip to control the compressor and outdoor fan. Its main advantages are: easy to use, easy to transplant, and does not require a powerful Chip resources, hardware resources and higher PCB (Printed Circuit Board, printed circuit board) wiring requirements. [0004] However, the adoption of the dual-chip control method not only increases the hardware cost, but also increases the control complexity of the air conditioner....
