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

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.
