Pay attention to energy efficiency ratings and APF values: Air conditioner energy efficiency ratings in China are based on national standards, with Level 1 being the most energy-efficient. When purchasing, you should not only look at the energy efficiency rating (the new national standard has 5 levels) but also pay attention to the APF (Annual Performance Factor) value. Within the same energy efficiency rating, a higher APF value indicates greater energy savings.
Choose energy-saving technologies: Prioritize air conditioners using full DC inverter technology. Their compressors, fans, and other core components are all inverter-driven, resulting in greater energy savings compared to air conditioners with only some inverter components. Additionally, consider products with one-button energy-saving modes (such as ECO or Cool Energy Saving modes) and high-temperature self-cleaning functions. The former automatically optimizes operating strategies, while the latter maintains high efficiency.
Match the horsepower to the room size: Choose an air conditioner with the appropriate horsepower based on the room area. Too low a horsepower will cause the air conditioner to operate under continuous high load, while too high a horsepower will cause the compressor to frequently start and stop, both increasing energy consumption.
