Abstract

Drop-in tests were conducted using R290/R32 (31:69) or R290/DME (65:35) mixture in a ice-cream maker for possible replacement of R-502 and R-404A. At the standard room temperature ($20^{\circ}C$), the time required for initial ice-cream making was 4'7' for R290/32, 4'39' for R404A and 4'59' for R290/DME. The electric energy consumed was 436 kJ for R290/32, 425 kJ for R404A and 439 kJ for R290/DME. The mass flow rate as well as the temperature and pressure data are also provided.
