基于运行时间的变频型房间空调器季节能效比和潜力温度分析

Study on Seasonal Energy Efficiency Ratio and Potential Temperature of Variable-Speed Room Air Conditioner Based on Running Time

计算了3台变频型房间空调器基于北京、上海、广州3种运行时间的季节能效比(SEER);采用运行时间频数(RTF)表征空调器运行时间在温度区间上的分布规律;绘制了3台空调器基于3种运行时间的制冷量和耗电量分布图.结果表明:RTF最大值对应的温度越小,SEER越大;RTF在低温段累计速度越快,SEER越大;空调器制冷量和耗电量在温度区间上的分布规律由运行时间决定;基于运行时间的制冷量和耗电量分布图能够直观反映当地的潜力温度,可为空调器性能的优化和选型提供参考依据.

Seasonal energy efficiency ratio （SEER） of three variable-speed air conditioners under three kinds of running time was analyzed, respectively. Running time frequency （RTF） was taken to character ize 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.
