  Energetic and Exergetic Investigation on Vapor Compression Refrigeration System Using Ag₂O-R134a Nanofluid as Refrigerant

  By R Jyothu Naik, Sachin G Ghalme, Nandkishor M. Sawai, P Kumar

  Abstract: This paper experimentally explored energetic and exergetic performance investigation of VCR System using Ag₂O-R134a Nanofluid as Refrigerant. The integration of silver oxide (Ag₂O) nanoparticles within polymer and composite materials offers promising avenues for enhancing the thermal and physical properties of advanced systems. The energetic and exergetic performance study of VCR were investigated with test parameters including compressor power consumption, cooling capacity, coefficient of performance (COP), discharge temperature, irreversibility in the …

  Comprehensive Thermal and Environmental Investigation of An Enhanced Evacuated Tube Solar Water Heater with Wavy Tape and Latent Heat Storage

  By Punam Kumar Agade, Nitin Dubey, Rahul Agrawal

  Abstract: Evacuated tube solar collectors (ETSCs) are widely used for thermal energy applications; however, enhancing their thermal and exergetic efficiency remains a challenge. This study investigates performance enhancements through structural and material alterations. Four ETSC cases were tested experimentally, case-1: a standard ETSC, case-2: Wavy tape (WT) inserted ETSC, case-3: Phase change material (PCM) integrated ETSC, and case-4: Dual-Enhanced ETSC (PCM + WT). A binary eutectic PCM was utilized for latent …
