Abstract Seasonal energy efficiency ratio (SEER) of three variablespeed air conditioners under three kinds of running time was analyzed, respectively. Running time frequency (RTF) was taken to characterize the distribution of running time on temperature intervals. Bar graph was used to show the distribution of cooling load and energy consumption on temperature intervals. The results show that, the smaller the temperature under maximum RTF, the higher the SEER is. The faster the accumulation speed of RTF on low temperature intervals, the higher the SEER is. The regularity of distribution of cooling load and energy consumption on temperature intervals is decided by running time. The potential temperature can be showed on the bar graph, which has high reference value in performance optimization and selection of variable-speed room air conditioner.
