摘要

The performance enhancement of hydrocarbon mixture refrigerant R290/R600 (79/21 by wt %) was analyzed as an alternative to R12 and R134a, with and without the effect of magnetic field force at the condenser outlet. Six magnets with a Gauss level of 4000 each were attached on the refrigerant full liquid line of the condenser outlet. Experiments were conducted with R12, R134a, and R290/R600 mixture refrigerant at different condensing and evaporating tem peratures. The parameters investigated were refrigeration capacity, compressor power, and coefficient of performance. The test results showed that the R290/R600 refrigerant mixture had a 30.5-78% higher refrigeration capacity and a 4.6-28.2% higher coefficient of performance than that with R12 without magnetic field effect. The refrigerant R134a showed a slightly lower coefficient of performance than that of R12. The magnetic field force lowered the compressor power consumption by 1.5-2.4% and enhanced the coefficient of performance of the system by 1.6-2.5% compared with that with no magnets. The R290/R600 (79/21 by wt %) refrigerant blend can be considered as an alternative refrigerant for R12 and R134a, with or without the effect of magnetic field.
