Abstract

The invention discloses a frequency increasing method and system for a variable frequency air conditioner. The frequency increasing method comprises the steps that the environment temperature of the environment where the variable frequency air conditioner is located and the set temperature set by a user are acquired; whether an absolute value of a difference value between the environment temperature and the set temperature is larger than a temperature threshold value is judged; if yes, the first frequency increasing speed of a compressor is calculated through a fuzzy control algorithm according to the environment temperature and the compressor current, and the operation frequency of the compressor is increased according to the first frequency increasing speed; if not, the operation frequency of the compressor is increased according to the preset second frequency increasing speed; the first frequency increasing speed is higher than or equal to the second frequency increasing speed. According to the frequency increasing method and system, the frequency increasing speed of the compressor can be quickly increased to achieve the purpose of quick refrigerating or heating, and therefore great convenience is brought to a user.

Description

technical field [0001] The present invention relates to the technical field of frequency conversion air conditioners, in particular to a method and system for increasing the frequency of frequency conversion air conditioners. Background technique [0002] At present, in the household air conditioner market, due to its energy-saving and comfort effects, the share of inverter air conditioners is gradually increasing. It takes a long time for the inverter to increase the frequency to the rated frequency, which leads to poor cooling or heating effect when the inverter air conditioner is started. [0003] In the existing inverter air conditioners, a method of starting the DC inverter compressor is generally used. In order to ensure the oil return and noise problems of the compressor when the compressor is started, it generally adopts a fixed speed of 1Hz / s to increase the frequency. Therefore, it takes about 60 seconds for the compressor to rise from the start-up 1Hs to the rate...
