Use of Hydrocarbons and Other Blends as Refrigerant
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 1
Abstract
Abstract: This paper presents a study of different environmental friendly refrigerants of either hydrocarbon or Hydro fluoro carbons (HFC) class. Hydrocarbons (HCs) have zero ODP and very low GWP whereas HFCs have zero ODP but a quite higher GWP. Almost in all the cases, when R-134a was replaced with HCs the COP of the system was improved, ON time ratio and energy consumption was reduced. Due to a higher value of latent heat of HCs, the amount of refrigerant charge was also reduced as compared with HFC-134a. When hydro chloro fluoro carbons (HCFCs) were replaced with HFCs the system delivered a poor performance with increased energy consumption. When nano particles were added to the refrigerant, system delivered better performance with reduced energy consumption than that of pure refrigerant.
