Design of a tester table to make tests of the refrigeration thermodinamical cycle of vapor compression

Abstract

The tester’s table CRC­4 (Carnot’s Rverse Cicle ­4) like a learning way for the UVM’s students, shows in the fist contact with refrigeration equipments and systems all the components of those: Evaporator, Condensator, Compressor, and Expansion valve, as the way how those elements works into the system. In other ideas order, this tester table, is able to show a refrigeration’s system behavior in different work conditions. Identify all material changes (Refrigerant) as the calculation of some operation variables. This testes table was created with the propose to show in a easy way the vapor’s compression refrigeration cycle, proposed by fist time n 18824 by the French engineer Sadi Carnot . Its building is really simple, Has a cooled by water Evaporator and Condensator, a semi hermetical compressor , and an expansion, valve. Some secondary elements are present. The building cost of this tester table are 4.576,83 Bs.F, in the same way, some thermical charges has been calculated to three refrigerants (R­12, R­22 and R­134), obtaining that, the Tester’s table CRC­4 will be able t cover all these.
