Summary :
|
|
THE PRESENT WORK AIMS THE COMPUTATIONAL SIMULATION OF THE ENERGY EFFECTS OF THE SUBSTITUTION OF THE WORKING FLUID R-12 FOR THE R-134A IN COMPRESSION REFRIGERATION SYSTEM, WITHOUT MODIFYING THE ORIGINAL DESIGN OF THE MACHINE. THE SIMULATION WAS DONE THROUGH AN ALGORITHM OF SOLUTION OF NON LINEAR SYSTEMS BY THE NEWTON-RAPHSON METHOD IN LANGUAGE PASCAL. SYSTEMS OF EQUATIONS REPRESENTING THE FUNCTIONING OF ONE AND TWO STAGES VAPOR-COMPRESSION REFRIGERATION CYCLES HAVE BEEN IMPLEMENTED. SPECIAL ATTENTION IS PAID TO THE FRICTION LEAD LOSS THROUGH LINES AND VALVES AS WELL AS TO THE REALISTIC VARIATION OF THE COMPRESSOR ADIABATIC EFFICIENCY ACCORDING OF THE OPERATION CONDITIONS.
