Description

technical field [0001] The invention relates to the field of air conditioner production, in particular to a test system for an outdoor unit of a variable frequency air conditioner in a production process. Background technique [0002] Inverter air conditioner is an air conditioner using inverter compressor and fuzzy control technology, which can adjust the cooling speed according to the change of indoor temperature. Inverter air conditioners are compared with ordinary air conditioners. The compressor motor of ordinary air conditioners adopts AC asynchronous motors, and the speed remains unchanged, while inverter air conditioners use inverter compressors, which adjust the compressor speed through frequency changes, so that the cooling capacity changes continuously and adapts to air conditioners. load needs. [0003] The inverter air conditioner adopts the organic combination of inverter power supply, inverter compressor, electronic expansion valve and microcomputer technolog...
