Experimental evaluation of a vapour compression plant performance using R134a, R407C and R22 as working fluids

In this paper, the influence of the main operating variables on the energetic characteristics of a vapour compression plant, based on experimental results, is addressed. The experimental tests are performed on a single-stage vapour compression plant using three different working fluids, R134a, R407C and R22. The operating variables considered are the evaporating pressure, the condensing pressure and the superheating degree at the compressor inlet. The performance characteristics followed to analyse the energetic performance are the refrigerating capacity and the power requirements of the reciprocating compressor, presenting and discussing in this work the main experimental results obtained.
