变频空调器间歇供冷能耗特征测试分析*
Test and analysis of energy consumption characteristics of variable speed air conditioner intermittent cooling
摘要：
变频空调器间歇供冷时，间歇期室内温度的升高会使空调器在开机过程中出现一个能效比较低的阶段，间歇供冷模式下变频空调器的平均能效比低于连续供冷模式。因此，针对变频空调器间歇供冷是否一定能够降低空调器的用电量一直存在争议。选取上海地区某公寓中间层的南向房间作为研究对象，通过实际测试，研究了变频空调器间歇供冷时空调器供冷量及空调器用电量的变化特征。测试结果表明，变频空调器间歇供冷能够降低空调器的供冷量，但并不一定能够降低空调器的用电量。
Abstract：
For intermittent cooling of variable speed air conditioners, the indoor air temperature rising during the off-period results in EER dropping in the starting-up stage. Thus, the average EER of the variable speed air conditioner for the intermittent cooling mode is lower than that for the continuous cooling mode. So, it is a controversial issue whether the intermittent operation can definitely reduce the power consumption of the variable speed air conditioner. Taking a south-oriented room of an apartment on middle floor in Shanghai as the research object, analyses the characteristics of the cooling capacity and the power consumption during the intermittent cooling of the variable speed air conditioner by testing. The results show that the intermittent cooling of the variable speed air conditioner can reduce the cooling capacity, but it may not necessarily reduce the power consumption.
