Abstract

The invention discloses a frequency conversion air conditioner and a stop control method and a stop control device for a compressor of the frequency conversion air conditioner. The method comprises the following steps: acquiring current operating frequency of the compressor when a stop instruction is received by the frequency conversion air conditioner; judging a frequency reduction interval to which the current operating frequency of the compressor belongs; and acquiring a corresponding frequency reduction rate according to the frequency reduction interval to which the current operating frequency of the compressor belongs, and reducing the operating frequency of the compressor according to the acquired frequency reduction rate until the operating frequency of the compressor reaches preset stop frequency. The method is capable of performing section-by-section linear frequency reduction on the compressor at a preset frequency reduction rate when the stop instruction is received by the frequency conversion air conditioner, and the compressor stops operating after the operating frequency of the compressor reaches the preset stop frequency, and therefore tubing vibration and stress at the stop moment of the compressor are reduced, danger that tubing is broken is avoided, and system reliability is increased.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and in particular to a method for controlling the shutdown of a compressor in an inverter air conditioner, a device for controlling the shutdown of a compressor in an inverter air conditioner, and an air conditioner. Background technique [0002] In the inverter air conditioner, the refrigerant pressure and load are relatively large during high-frequency operation. If the compressor is stopped directly during high-frequency operation, the refrigerant pressure and load energy will be released instantly, which will cause vibration and stress on the compressor piping. If it is too large, it may even cause the pipe to break. Therefore, how to reduce the piping vibration and stress of the compressor when the inverter air conditioner is shut down has become an urgent problem to be solved at present. Contents of the invention [0003] The present invention aims to solve one of the technical ...
