Abstrakt
This study presents a new trend of natural and mixed refrigerants as the ideal refrigerants, environmentally friendly and an ideal solution to the problems of ozone-depleting substances and the surrounding environment. HFC refrigerants are presently the main swap for CFC and HCFC refrigerants in air-conditioning refrigeration systems. During this period of time much consideration has been paid to the conceivable utilize of fluorinated propene isomers for the substitution of HFC liquids, being much of the time high-GWP refrigerants. However, the available hydrofluoroolefins (HFOs) can't cover all the refrigeration, heat pump and air-conditioning systems when utilized as pure fluids this because the thermodynamic properties are not reasonable for all working conditions. Also, in this paper analyses the behavior of different new trends in the natural and mixed refrigerants and their areas of applications in air conditioning and refrigeration systems. Comparison of flow boiling heat transfer coefficient of the new mixture refrigerant and natural refrigerant are investigated in this study.
