| Summary: | According to special requirements of refrigerants used in centrifugal chillers, a new ternary mixture alternative, LXR2a, was proposed. The basic thermophysical properties and cycle performances of LXR2a were compared with those of R12. Moreover, the effects of different evaporating temperature, condensing temperature, super-heating temperature, and super-cooling temperature on the cycle performances were simulated. In addition, the leakage simulation was analyzed. The results show that LXR2a is a drop-in refrigerant with good performances and it may be a medium-term alternative to R12 in centrifugal chillers. |
