Abstract: With the promotion of the carbon peak and neutrality strategy, air conditioner energy saving is becoming more and more important. So a household air conditioner energy saving method based on regression analysis is proposed. Establish a model between the compressor running time and indoor temperature difference, and solve its coefficients through regression algorithm, the temperature difference can be calculated and the compressor frequency can be adjusted in advance, so the energy waste caused by excessive dehumidification and temperature adjustment can be avoided. The experiment results show that this method can save energy up to 10% which can be used widely.

Key words: Regression analysis, Calculate, Energy saving
