以R134a为工质的高温冷水系统性能实验研究

Experimental Study on the Characteristics of High-temperature Chilled Water System Using R134a as Working Fluid

针对以R134a为工质的高温冷水系统,分别在名义工况、变工况和部分负荷工况下进行了实验研究,分析了制冷量及能效比在不同工况下的变化规律。研究结果表明:高温冷水系统的制冷量和能效比受运行参数、负荷率的影响,在正常工况下运行能效比能达到6以上,明显高于传统的冷水系统。

With R134a as working fluid,experiments on high-temperature chilled water system were carried out respectively in nominal working conditions, variable conditions and partial load conditions. The refrigerating capacity and EER were analysed and the results showed they were influenced by operating parameters and the load rate. The system＇s EER can reach 6.0 at least when running under normal working conditions, which was obviously higher than the traditional chilled water system.
