Problems solved by technology

[0004] However, since the pressure of the air conditioning system is greatly affected by the indoor and outdoor temperatures, and the pressure of the system changes due to the compression of the refrigerant by the compressor after the compressor is started, the load of the compressor also changes, and the system disturbance increases. The closed-loop start-up method of the compressor is likely to cause the compressor to fail to start, so the above start-up method is not applied to the air-conditioning system

Embodiment Construction

[0048] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0049] figure 1 A schematic flowchart of a control method 100 for starting a compressor of an air conditioner provided by an embodiment of the present invention is given. Such as figure 1 The execution subject of the shown control method 100 may be an air conditioner or a control device on the air conditioner. Control method 100 includes:

[0050] 110. According to the rotational speed of the compressor rotor, it is judged whether the compressor is in a stopped state.

[0051] 120. If the compressor is in the stopped state, detect the air conditioner state, and acquire the previous compressor startup mode.

[0052] 130. Determine the current compressor startup mode according to the air conditioner status and the...

Abstract

The invention relates to a start control method and device of an air conditioner compressor. The control method comprises the steps that whether the compressor is in a stop state or not is judged according to the rotation speed of a rotor of the compressor; if the compressor is in the stop state, the air conditioner state is detected, and the last compressor start mode is obtained; the present compressor start mode is determined according to the air conditioner state and the last compressor start mode; the compressor is controlled to be started in the present compressor start mode; and after the compressor is started in the present compressor start mode, the compressor is controlled to operate at a preset speed. The start control method and device of the air conditioner compressor can determine the start ways of the compressor according to the actual state of an air conditioner system, and noise and energy consumption can be reduced while the effect that the compressor is easily started is ensured.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a control method and a control device for starting an air conditioner compressor. Background technique [0002] Inverter air conditioners are more energy efficient and efficient than fixed frequency air conditioners. At present, the start-up control method of the inverter compressor used in the inverter air-conditioning room includes the following four stages: (1) DC excitation positioning; (2) open-loop pulling; (3) open-loop to closed-loop; (4) closed-loop control. In the two stages of DC excitation and open-loop pulling, in order to prevent startup failure, the starting current / torque must be greater than the starting current / torque required for actual starting. However, excessive starting current / torque will generate vibration and noise, which will affect user comfort. , and consumes a lot of energy. [0003] Another motor starting method in the inverter industry i...
