Projeto de bancada de refrigeração: ciclo de compressão em paralelo

Abstract

The refrigeration benches use the standard vapor compression refrigeration cycle. In industry, generally the standard vapor compression cycle is inadequate, then series or parallel vapor compression cycles are used, by reducing the cost and reaching very low temperatures. A parallel compression cycle bench for studying the refrigeration cycle was dimensioned, with pressure gauges and temperature gauges in the circuit, for better visualization of temperature and pressure variations, as well as losses in the system. The refrigerant that provides the adequate cooling capacity was chosen, taking into account its cost. The bench will be used in a didactic way, to demonstrate a more complex compression refrigeration cycle. Students contact with the parallel compression refrigeration cycle, and with the thermodynamic process that occur, add a lot of knowledge, and the visualization of the system makes it easy to understand what is happening at each stage of the process.
