摘要

建筑可持续发展的要求是要有环保的制冷和供暖系统。在冷却系统中使用相变材料(PCM)是最小化有功功率需求以及减小蒸汽压缩制冷VCR系统组件尺寸的潜在解决方案。制作了Air-PCM (T25™)热交换器的原型，并在实际环境条件下进行了测试。用盐水合物作为PCM的实验试验表明，当PCM的75%凝固时，冷却效果最大，为2.05 kW。基于结果，发现基于pcm的被动冷却有可能将空调(AC)的尺寸(制冷量)减小13%至46%。

PERFORMANCE ANALYSIS OF AN ENERGY-EFFICIENT PCM-BASED ROOM COOLING SYSTEM

The requirement for sustainable development for buildings is to have environmentally friendly cooling and heating systems. The utilization of phase change materials (PCM) in the cooling system is a potential solution for minimizing active power requirements as well as for reducing the size of components of a vapor compression refrigeration VCR system. A prototype of an Air-PCM (T25™) heat exchanger was fabricated and tested in actual environmental conditions. Experimental trials using a salt hydrate as PCM have shown the maximum cooling effect of 2.05 kW when 75% of the PCM was solidified. Based on the results, it is found that PCM-based passive cooling has the potential to reduce the size (cooling capacity) of the air conditioner (AC) in the range of 13 to 46 %.
