要約

The steady state thermofluid behavior of a visi-cooler has been mathematically modeled using a distributed parameter technique for R-12 and R-134a/R-290/R-600a mixtures. The pressure drop in condenser and evaporator tubes, pressure-volume diagram, temperature glide, compressor power, and per day energy consumption for various operating conditions have been extracted. Experiments also have been conducted for both the refrigerants for similar operating conditions. The simulation revealed that a mixture of R-134a, R-290, and R-600a with mass percentage of 91%, 4.068%, and 4.932%, respectively, is more efficient than R-12 in all performance aspects. The deviation of experimental results from the simulated values is observed to be within ±12%. The experiments also showed that the percentage reduction in the per day energy consumption with the mixture is between 10.8% and 19.6% for the tested conditions.
