Problems solved by technology

[0002] In related inverter air conditioners, the pressure and load of the refrigerant are high during high-frequency operation. If the compressor is stopped directly, the pressure of the refrigerant and the energy of the load will be released instantly, resulting in excessive vibration and stress of the piping, and even the risk of pipe breakage
In the related art, the frequency reduction method is usually used to control the shutdown of the compressor, that is, to control the compressor to reduce the frequency to a low frequency and then stop the compressor to reduce the vibration and stress of the piping during the shutdown time. However, its disadvantages are: At the moment when the compressor of the inverter air conditioner stops, there may still be large piping vibration and stress

Abstract

The invention discloses an air conditioner as well as a shutdown control method and device for a compressor of the air conditioner. The method comprises steps as follows: a rotor phase with the minimum load of the compressor is acquired; in the shutdown process of the air conditioner, the rotor position of the compressor is acquired, and whether a rotor of the compressor is located in the rotor phase with the minimum load of the compressor or not is judged according to the rotor position of the compressor; if the rotor of the compressor is judged to be located in the rotor phase with the minimum load of the compressor, the compressor is controlled to stop running, so that produced tubing vibration and stress are smaller, then the tubing vibration and stress at the stop moment of the compressor are effectively reduced, and the risk of tubing breakage is prevented.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a method for controlling the shutdown of a compressor in an air conditioner, a device for controlling the shutdown of a compressor in an air conditioner, and an air conditioner with the device. Background technique [0002] In related inverter air conditioners, the pressure and load of the refrigerant are high during high-frequency operation. If the compressor is stopped directly, the pressure of the refrigerant and the energy of the load will be released instantly, resulting in excessive vibration and stress of the piping, and even the risk of pipe breakage . In the related art, the frequency reduction method is usually used to control the shutdown of the compressor, that is, to control the compressor to reduce the frequency to a low frequency and then stop the compressor to reduce the vibration and stress of the piping during the shutdown time. However, its disadvantag...
