Inverter air conditioner and energy-saving operation control method thereof

Abstract

The invention discloses an energy-saving operation control method for an inverter air conditioner. The energy-saving operation control method for the inverter air conditioner comprises the following steps of establishing energy-saving operation parameter libraries which correspond to different working conditions and comprise energy-saving working frequency; enabling the inverter air conditioner to work in the inverter control mode; detecting the indoor temperature T1i and the outdoor temperature T4i; judging the degree of closeness of the indoor temperature T1i and the set temperature Ts; and when the degree of closeness achieves a preset energy-saving control preset value, enabling the inverter air conditioner to invoke a corresponding energy-saving operation parameter to work according to the working condition. Because the energy-saving operation control method for the inverter air conditioner, which is disclosed by the invention, is characterized in that the corresponding energy-saving operation parameter is invoked for working when the degree of closeness achieves the preset energy-saving control preset value, the inverter air conditioner is prevented from working under the low-frequency condition so as to improve the total energy efficiency of the inverter air conditioner, and the energy saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an inverter air conditioner and its energy-saving operation control method. Background technique [0002] The existing control method of the inverter air conditioner is to control the operating frequency of the compressor according to the difference between the set temperature and the indoor ambient temperature by using the user's set temperature and the indoor ambient temperature as control parameters. The frequency conversion air conditioner adopting this method changes from large to small as the load decreases, and when the indoor ambient temperature is equal to or lower than the set temperature, the operating frequency of the compressor of the variable frequency air conditioner decreases continuously to the lowest operating frequency. [0003] Because the compressor is affected by the clearance volume, the compressor has an optimal energy efficiency operating frequen...

AI Technical Summary

Problems solved by technology

[0003] Because the compressor is affected by the clearance volume, the compressor has an optimal energy efficiency operating frequency under a certain working condition. If the operating frequency of the compressor is too low, the energy efficiency will decrease instead.

Therefore, when the operating frequency of the existing inverter air conditioner drops below the optimal energy efficiency operating frequency, its corresponding energy efficiency ratio will gradually decrease.
