An investigation into the applicability of R450A as a replacement for R134a in heat pump tumble dryers was made in collaboration with Gorenje, d.o.o.This paper presents the results of an experimental study evaluating R450A as a possible drop-in replacement for R134a in household heat pump tumble dryers. A heat pump Read more…
Existing capillary tube models rely heavily on friction factor correlations, which enable the specification of the relative surface roughness. However, measuring the surface roughnesses of capillary tubes is a time consuming task, which requires specialized equipment. In this research we have developed a friction factor correlation, which does not Read more…
