... heat removal process?” As an answer, this paper presents a direct comparison of single-phase water, a 50% water–ethylene glycol mixture and several two-phase refrigerants, including the new fourth generation refrigerants HFO1234yf and HFO1234ze. Two-phase cooling using HFC134a had an average junction...

...P. Zhang; Z. W. Ma; R. Z. Wang The application of phase change material slurry to the refrigeration and air conditioning system opens a new way for energy saving and reduction of the quantity of refrigerant in the system involved because it can serve as both the energy storage...

...Zahid Ayub Global environmental and energy concerns have prompted the heating, ventilating, air-conditioning, and refrigeration industry to revisit the use of natural refrigerants. Nearly all natural refrigerants have superior transport properties as compared with synthetic refrigerants; however...

... refrigerants was developed for the straight capillary tube on the basis of the experimental data of R-407C of the present study, and the data of R-134a, R-22, and R-410A measured by other researchers. Additionally, a refrigerant-specific correlation for the spiral capillary was also proposed on the basis...
