Experimental testing of the heat transfer in a Lorenz process using zeotropic mixtures.
Eksperimentalno preskusanje prenosa toplote v Lorenzovem postopku z uporabo zeotropnih zmesi./ Experimental testing of the heat transfer in a Lorenz process using zeotropic mixtures.
Summary
A comparison has been made between the thermodynamic efficiency of R22 and a substitute zeotropic mixture R407C in a system operating under the same conditions. The construction of a refrigerating system that uses R22 and R407C is presented, along with measurements of all the relevant data (temperature, pressure and flow rate), their acquisition, and their analysis. The results show that the refrigerant R407C is a good substitute for R22 at higher evaporation temperatures. Although the theoretical results suggest that R407C will increase efficiency compared with R22, the experimental results did not confirm this.
