Performance Test of a R134a Centrifugal Water Chiller
Jinhee Jeong,Pil-Hyun Yoon,Ghil-Yeung Kim,Hyeonkoo Lee 대한설비공학회 2002 International Journal Of Air-Conditioning and Refr Vol.10 No.2
A centrifugal water chiller using alternative refrigerant R134a has been developed. The prototype was designed to have refrigerating capacity of 300 RT. Its compressor employs a single high-speed impeller, airfoil diffuser and collector. Newly developed, enhanced tubes were installed in the evaporator and the condenser to reduce the required head for the compressor. Off-design characteristics at various conditions, performance test of the compressor and analysis of the refrigeration cycle were performed. So the probability of use in part load condition was checked and the direction for revision was suggested.
