Frequency reduction control method of frequency conversion air conditioner and frequency conversion air conditioner

Abstract

The invention belongs to the field of air conditioners, and particularly discloses a frequency reduction control method of a frequency conversion air conditioner. The air conditioner is provided withmultiple frequency reduction modes and multiple outdoor environment temperature reference ranges, the multiple outdoor environment temperature reference ranges are not overlapped, the different frequency reduction modes correspond to different compressor current control threshold values under the same outdoor environment temperature, the same frequency reduction mode corresponds to the different compressor current control threshold values under the different outdoor environment temperature reference ranges, when a frequency reduction instruction is received, according to the detected current outdoor environment temperature, the outdoor environment temperature reference range of the temperature is determined, according to the outdoor environment temperature reference range, the compressor current control threshold value under the frequency reduction mode in the frequency reduction instruction can be determined, and according to the current control threshold value, a compressor is correspondingly controlled. According to the control method, through mode dividing current control, in combination with temperature zone dividing current control, the frequency of the compressor is controlled, the power of the whole air conditioner is reduced, and the aim of reducing the power consumption is achieved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a frequency reduction control method of an inverter air conditioner and the inverter air conditioner. Background technique [0002] The starting power of the compressor is an important parameter of the air conditioner, and the energy saving of the air conditioner is an important indicator for the user to measure the product. Usually users judge the energy saving degree of an air conditioner through the energy efficiency ratio. At present, due to the special situation of some underdeveloped countries, some air conditioners in the market have developed air conditioners with reduced power to control power consumption, so as to meet the country's power grid supply demand. [0003] However, the existing air conditioners with power reduction or power consumption functions in the industry directly use the control of the total current or total power of the air condi...

AI Technical Summary

Problems solved by technology

In fact, when the air conditioner is running under different working conditions, due to the different environmental loads, the power and current of the air conditioner under different environmental working conditions are very different. Under this condition, it is impossible to achieve a unified qualitative standard and achieve a qualitative power reduction effect. As a result, the power consumption of the air conditioner after frequency reduction varies greatly with the ambient temperature, which cannot be maintained.
