Experimental study of a domestic refrigerator using (SiO 2 /PAG oil/R- 134a) nano-refrigerant as a replacement for pure R-134a

Cost-Effective COP Enhancement of a Domestic Air Cooled Refrigerator using R-134a Refrigerant

This paper presents a cost-effective method to increase the COP and utility of a domestic refrigerator using R-134a refrigerant. A cabin was installed on the top of a domestic refrigerator with condenser coils of refrigerator serving as heating coils inside the cabin. Known quantity of water was heated by the condenser coils (due to convection currents) thereby increasing the overall COP of the...

High Efficiency R-134a Compressor for Domestic Refrigerator

Because of high growth in economy and rapid increase in energy consumption , the government has made efforts to resolve the difficulties of the shortage of energy by restricting the amount of electrical energy consumption for home electrical products and several products consuming energy. Especially, the rules specified how the amount of electrical energy consumption was tested is expected to r...

Development of HFC-134a Compressor for Domestic Refrigerator

Emission of Refrigerant R-134a from Mobile Air-Conditioning Systems

Evaluation of HFO-1234yf as a Potential Replacement for R-134a in Refrigeration Applications

In response to concerns about the contribution of fluorocarbon refrigerants to global climate change, a new, more environmentally sustainable, refrigerant molecule has been developed and is being evaluated. This new molecule is the hydrofluoroolefin 2,3,3,3,-tetrafluoroprop-1-ene, or HFO-1234yf. The molecule has been shown to be stable inside refrigeration equipment, but to quickly decompose if...
