An experimental investigation of ternary refrigerant blends performance proposed as substitutes for CFC-12.

Author(s) : SAMI S. M., SCHNOTALE J., SMALE J. G.

Summary

Thermal capacity, COP, pressure ratio, system pressures, temperatures and compressor power are discussed for several compositions of the blend. This has been accomplished with the help of a brine/water vapour-compression experimental rig. Results obtained indicated that the performance of the proposed blends, has a strong dependency on the blends concentrations. The proposed blends have superior performances over R12, in both refrigeration and air conditioning applications. The proposed blends need a slightly higher pressure than R12.
