摘　　要：在济南某基站安装了笔者自主研发的自然冷源降温系统,对其室内降温特性进行了测试分析。结果显示,其节能效果随室外温度降低而提高。对测试数据进行了拟合分析,代入济南近6年天气温度离散逐时值,计算了不同室内温度上限值时的能耗数据,结果显示新系统节电率和节电量随上限值的升高而分别提高和降低。基于2016年天气数据,室内温度上限值为22,26,28,30℃时自然冷源降温系统的节电量分别为3 425.76,2 929.88,2 403.97,1 784.22 kW·h,节电率分别为28.44%,37.66%,42.57%,50.77%。Base on a free cooling energy efficient unit developed by authors, installed in a base station in Jinan, tests the performances of indoor temperature decrease. The experimental results show that the energy saving effect increases rapidly with outdoor temperature decrease. Based on fitting and analysis of experimental data, inputting hourly discrete weather temperature of Jinan to calculate energy consumption with different upper limit indoor temperatures in recent 6 years, the calculated data show that power saving rate and power saving of the new system increases and decreases respectively with increasing upper limit. Based on the weather data in 2016, energy saving of the new system is 3 425.76, 2 929.88, 2 403.97, 1 784.22 kWh at upper limit temperatures of 22, 26, 28, 30 ℃, then corresponding energy saving rates are 28.44%, 37.66%, 42.57% and 50.77% respectively.
