Problems solved by technology

If the compressor works at a high speed for a long time, it is easy to cause the compressor to work in a high temperature range for a long time, which will increase the internal load of the compressor and the air conditioner, which will not only affect the service life of the compressor, but also affect the life of the air conditioner, and increase the power. If the temperature of the compressor is too high, one method may cause compressor failure and damage, on the other hand, it will reduce the cooling effect

Abstract

The invention relates to a rotation speed control method for an air conditioner compressor, which comprises the following steps: setting the rotation speed value of an air conditioner compressor into N rotation speed shifts from low to high, and setting a corresponding rotation speed adjusting coefficient interval and a rotation speed instruction value; acquiring indoor temperature and outdoor machine temperature in real time; according to a cooling temperature value set for an air conditioner, the indoor temperature, an outdoor machine standard temperature setup value and the outdoor machine temperature, calculating a rotation speed adjustment coefficient; according to the calculated rotation speed adjustment coefficient, confirming the rotation speed adjustment coefficient interval, confirming a corresponding rotation speed instruction value; adjusting a current rotation speed value of the air conditioner compressor to be equal to the calculated rotation speed instruction value. By adopting the rotation speed control method for the air conditioner compressor, the service life of the air conditioner compressor can be prolonged, and the cooling effect of the air conditioner compressor can be improved.

Description

Technical field [0001] The invention relates to a method for controlling the speed of an air conditioner compressor. Background technique [0002] The compressor is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it by clicking to operate, and discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. If the compressor is working at a high speed for a long time, it will easily cause the compressor to work in an excessively high temperature range for a long time, which will increase the urgent load of the compressor and the air conditioner, which will not only affect the service life of the compressor, but also affect the service life of the air conditioner, and increase the power. If the compressor temperature is too high, one method may cause the compressor to malfunction and damage, and on the other han...
