Method and device for configuring parameters of frequency converter of air conditioner

Abstract

The invention belongs to the technical field of air conditioners, particularly relates to a method and device for configuring parameters of a frequency converter of an air conditioner and aims at solving the problem that a frequency conversion compressor cannot work in a stable state due to the fact that obtained local characteristic parameters of a compressor motor are directly applied to vectorcontrol of a frequency conversion controller in the prior art. The method for configuring the parameters of the frequency converter of the air conditioner comprises the steps of identifying local characteristic parameters of the compressor of a frequency conversion air conditioner according to electric parameters of the frequency conversion air conditioner; matching the local characteristic parameters with prestored motor parameters of multiple types of compressors to obtain the type of the compressor of the frequency conversion air conditioner; and obtaining motor parameters and control parameters of the compressor of the frequency conversion air conditioner for control of the frequency conversion controller of the frequency conversion air conditioner on the compressor of the frequency conversion air conditioner on the basis of the type of the compressor of the frequency conversion air conditioner. According to the method provided by the invention, a potential quality hazard caused byan artificial setting error can be avoided and complete and accurate motor parameters and control parameters of the compressor can be applied to vector control.

Description

Technical field [0001] The invention belongs to the technical field of air conditioners, and specifically relates to a method and a device for configuring parameters of an air conditioner frequency converter. Background technique [0002] In inverter air conditioners, in order to simplify production management and reduce the types of inverter controllers, usually a hardware specification inverter controller will match multiple types of inverter compressors, but the motor parameters of different compressors are different, and the inverter controllers The controlled parameters are also different. The common method is to store the motor parameters and control parameters corresponding to multiple compressors in different areas of the same non-volatile memory of the inverter controller. In the air conditioning production or after-sales maintenance process, it needs to be compressed according to the inverter controller drive. The specific model of the machine is used to select the dat...
