摘 要： 针对机房内热负荷不均匀的情况，设计了一种吊顶式机房专用空调机。其目的是利用双侧输出不同冷量来提高对机房设备的冷却效果，保持机房内温度分布均匀。通过对样机的实验研究，分析了空调机在被控室内温度25℃，变冷凝温度条件下的综合性能以及室内热源变化对机组能效比的影响。实验结果表明，在室内热负荷不均匀条件下，这种新型机房专用空调机能够达到要求的制冷效果。说明该空调机具有较好的实用价值。 关键词： 机房空调机 实验研究 能效比 Experimental Study On Room Air Conditioner Outputting Different Cold Quantity From Two Sides Liu Yang Zang Runqing Liu Eyu Zhao Xiaozhi Major Laboratory of Refrigeration in Tianjin, Refrigeration and Air Conditioning Engineering Department in Tianjin University of Commerce, Tianjin 300134, China Abstract: According to indoor thermal load uneven situation, a type of ceiling room air conditioner is developed. The purpose is to improve the cooling effect of computer equipments by outputting different cold quantity from two sides and to keep temperature well-distributed. By experimental study of prototype, the comprehensive performance of this air conditioner under indoor temperature 25℃ and varietal condensing temperature is analyzed. The change of heat source and its effects on air conditioner EER are also discussed. The experimental results show that this new type of room air conditioner can satisfy refrigeration requirement in indoor thermal load uneven condition. This shows that the air conditioner has good practical value.
