| Popis: | This paper presents the effects produced by a suction/liquid heat exchanger installed in a refrigerating cycle, evidencing that, its use can improve or decrease the system performance depending on the operating conditions. Attention is focused on developing an easy operating method in order to predict the behaviour of the system introducing the heat exchanger, changing the operating conditions and/or the refrigerant fluids. To this aim, 19 different ozone friendly fluids (R-22, R-32, R-152a, R-125, R-134a, R-236a, R-227a, RC-318, R-410A, R-413A, R-407C, R-417, R-502, R-507A, R-717, R-290, R-600, R-600a and R-1270) have been considered, varying evaporating and condensation temperatures, respectively in the range −40 °C/10 °C and 25 °C/50 °C. The advisability of the installation of the heat exchanger can be evaluated as a function of thermodynamic properties. Furthermore, a simple chart allowing to verify the effectiveness of installation of heat exchanger has been developed for each refrigerating fluids and for the specified operating conditions. |
