摘要
在焓差实验室中模拟家用空调器的实际运行环境,相同条件下对比研究相同制冷量的定频和变频空调器的节能舒适特性。结果表明:相同条件下定频空调器能使室内更早的达到设定温度,当空调器设定温度16℃,室外温度35℃时,定频和变频空调器的耗电量达到相同的时间为11h,室外温度为40℃时,定频和变频空调器的耗电量达到相同的时间为6.3h,室外温度越高,定频和变频空调器耗电量相同的时间越提前,变频空调器需要更长的时间才能体现出节能优势;室外温度35℃时,运行变频和定频空调器,室内不同高度之间的温差分别在0.2℃~0.5℃和0.7℃~1℃,室内温度波动周期分别为2.4h和0.25h,变频空调器温差低于定频空调器,且波动周期大,室内温度变化缓慢,舒适性优于定频空调器。
The energy saving and comfort were investigated under the same experimental conditions in enthalpy difference lab. The results show that the constant - speed air - conditioners can make the room reach the set temperature quickly under the same conditions. When the power consumptions of the constant - speed and variable - speed air - conditioners reach the same, the time is 11 hours at the outdoor temperature of 35℃ and 6.3 hours at the outdoor temperature of 40℃, so the higher the out-door temperature is, the earlier the time of the same power consumption is, the variable - speed air - conditioner needs more time to reflect the advantage of energy saving. Operating constant - speed and variable - speed air conditioner at the outdoor tempera- ture of 35~C, the temperature difference is 0.2℃~0.50℃ and 0.7℃-1℃ at different heights respectively, and the fluctuation cycle of the indoor temperature is 2.4h and 0.25h respectively, the comfort of the variable - speed air - conditioner is better than the constant - speed air - conditioner.
