Method for controlling energy-saving operation of frequency converting air conditioner

Abstract

The invention discloses a method for controlling the energy-saving operation of a frequency converting air conditioner. The method for controlling energy-saving operation comprises the following steps of: obtaining refrigerating capacity / heating capacity of different frequency bands under a rated working condition, the refrigerating capacity / heating capacity under different working conditions anda correcting value of input power by a test; setting target temperature; calculating the power consumption of an outdoor air conditioner and time t2 when the set temperature is reached under different targets K3'; and finally finding out the optimal target K3' with least power consumption, which meets the condition that t2 is smaller than t1 (t1 is the longest time allowed to take to reach the set temperature) and further obtaining the energy-saving operating frequency f of a frequency converting compressor. By using the method, the air conditioner has less power consumption on the premise ofmeeting the requirement on the comfortableness of a user after entering an energy-saving mode, thereby improving the energy efficiency of the frequency converting air conditioner.

Description

Technical field: [0001] The invention relates to the field of air conditioners, in particular to a control method for energy-saving operation of frequency conversion air conditioners. Background technique: [0002] With the continuous popularization of the concept of low-carbon environmental protection, inverter air conditioners are favored by many consumers because of their energy saving, high efficiency, environmental protection and comfort, so the sales of inverter air conditioners are increasing year by year. According to the requirements of national standards, the air conditioners currently on the market need to be marked with energy efficiency grades, as an important performance index of air conditioners to guide consumers in purchasing air conditioners. The air conditioner energy efficiency stipulated in the standard is obtained in the enthalpy difference laboratory according to the standard requirements, under the working conditions and methods specified in the stand...

AI Technical Summary

Problems solved by technology

The air conditioner energy efficiency stipulated in the standard is obtained in the enthalpy difference laboratory according to the standard requirements, under the working conditions and methods specified in the standard. Although it is relatively close to the actual use of the air conditioner, due to the difference in the use environment of the inverter air conditioner and the user's setting habits, There are still some differences in the actual energy efficiency of inverter air conditioners
