A novel double-temperature chiller with zeotropic mixture R32/R236fa is proposed in this paper, and chilled water with two different temperatures is produced, such as low temperature water (T-L,T-out = 7 degrees C) and high temperature water (T-H,T-out = 16 degrees C). An experimental setup is established to test the performance of the chiller. Effects of mass fraction of R32 in mixture R32/R236fa (M (R32)), TL,out, TH,out and the heat transfer media flow rate on the performance of the chiller are studied. When TH,out is 18 degrees C, T-L,T-out is 8 degrees C and M (R32) is 0.6, COP and refrigerating capacity are 4.11 and 4.42 kW, respectively. COP and refrigerating capacity increase as M (R32) increases. Exhausting pressure of the chiller increases with the increase of M (R32). As M (R32) is 0.6, exhausting pressure is about 1.95 MPa. Compression ratio decreases with the increase of M (R32). When M (R32) increases from 0.3 to 0.6, the compression ratio decreases from 3.0 to 2.9. (C) 2016 Published by Elsevier Ltd.
