Auxiliary frequency converting control method and system of air conditioner and variable frequency air conditioner

Abstract

The invention relates to the technical field of air conditioners and discloses an auxiliary frequency converting control method and system of an air conditioner and the variable frequency air conditioner. The auxiliary frequency converting control method of the air conditioner comprises the steps that the first indoor temperature and the second indoor temperature before and after a first preset time period of the air conditioner are acquired, and the second indoor temperature is compared with an expected temperature; when the difference value between the second indoor temperature and the expected temperature is not larger than an auxiliary control triggering threshold value, the indoor temperature difference value corresponding to the first preset time period is determined according to the first indoor temperature and the second indoor temperature, wherein the auxiliary control triggering threshold value is smaller than a main control triggering threshold value triggering the main frequency converting control system to execute main frequency converting control actions; the auxiliary frequency converting amount is determined according to the indoor temperature difference; and according to the auxiliary frequency converting amount, a compressor is triggered to execute frequency converting actions. The correction of the frequency of the compressor is achieved according to the temperature rising and decreasing of the indoor temperature, and the temperature fluctuation caused after the indoor temperature reaches a user set temperature is prevented.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an auxiliary frequency conversion control method and system for an air conditioner and a frequency conversion air conditioner. Background technique [0002] Inverter air conditioners achieve the purpose of controlling room temperature by controlling the speed of the compressor's speed. Due to the advantages of low power consumption and high comfort, inverter air conditioners have become more and more popular among users. The compressor is the core component of the inverter air conditioner. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, and discharges high-temperature and high-pressure refrigerant gas through the exhaust pipe to provide power for the refrigeration (heating) cycle. [0003] When the heat pump inverter air conditioner is started each time, it first performs cooling or heating with the maximum power and maximum air volume,...
