Now your question was can we simply replace R600a with R134a ? Les meubles frigorifiques (vitrines réfrigérées, armoires, congélateurs, distributeurs de glace, etc.) The simulation is a transient turbulent model. However, if by 232 and 93 you mean that total cooling capacity is 325 W, so the product should be an SBS. Today we work on three refrigerants and see what best among them and what is advisable. I’m sorry but you really need a proofreader, if not an editor. Hi Wilber, To change a system from R600 to R134a is easy.. All you have to do is change the comp, cond, evap, suction pipe and the capillary. C’est … R134a is used in organic Rankine cycle for energy extraction from low temperature waste flue gas from different industries. Two properties are critical: the ozone depleting potential (ODP) and the global warming potential (GWP). 3) Cp of R600a much  higher than R134a. But when I want to calculate the mixture of ammonia and water the following error is shown: h = refpropm('h','T',288,'P',1e2,'water','ammonia',[0.7 0.3]).
