Experimental data for flow boiling of R450A in a horizontal tube

“…For different applications, Gatarìc and Lorbek [10] tested R450A in household heat pump tumble dryers and Molinaroli et al [11] in a water-to-water heat pump, with similar outcomes related to the energy consumption and efficiency (not much different from R134a) and heating capacity (slightly reduced because of the lower condensation pressure with respect to R134a). Several numerical approaches including Artificial Intelligence have also been followed to investigate the possible use of R450A in refrigeration systems (Belman-Flores et al, 2017 and Zendehboudi et al, 2019) [12] [13] and in waste heat-solar driven ejector heat pumps for simultaneous heating and cooling (Al-Sayyab et al, 2021) [14], all with encouraging and positive outcomes.…”

Energy Analysis of Vapor Compression Refrigeration Cycle Using a New Generation Refrigerants with Low Global Warming Potential

“…HFO is an unsaturated HFC and it is the fourth generation of fluorinated gases [7][8][9]. Nowadays, the attention of all researchers is focused on the feasibility of replacing HFC R134a with HFOs [10][11][12][13]. Many works are currently in search of new ecological fluids which can have less impact on the ozone layer thus also on the global warming of our planet.…”
