“…There is another nanoparticle, for example, CeO2, ZnO, and SiO2 are accessible with better thermophysical and warmth move capacities. In this experimentation the Cerium Oxide and Zinc Oxide nanoparticles in the size of around 20-30nm and 30-50nm separately added with the homegrown R134a refrigerant [13,14]. This is around a 6.9 percent rise.…”

At the present scenario, the action of ensuing the philosophy of reducing energy consumption and saving it for longer period without drop off in performance is increased. On the other hand, global warming and ozone layer depletion become foremost challenges. These concerns are takes place in Thermal systems like refrigerator and air conditioning. To resolve the above challenges, the nano refrigerants are used in refrigeration, which has previously got the attention due to its distinctive properties such as thermal conductivity. They also have the potential to improve the heat transfer performance of refrigeration. This project interrogated on the performance of domestic refrigeration system using normal condenser and microchannel condenser with and without nanoparticles. The Cerium oxide and Zinc oxide nanoparticles in the size of about 20-30nm and 30-50nm respectively with R134a domestic refrigerant were used. The experimentation carried out using 2 gm ofCeO2and ZnO nanoparticles in three different ratios [0.5:1.5,1:1 and 1.5:0.5] with R134a refrigerant. Hereby, the result conquered that 33.3% increase in the Actual COP of domestic refrigeration system using normal condenser with 1:1 ratio of nanoparticles when compared with the refrigeration system using microchannel condenser with and without nanoparticles.

India is one of the largest contributors to the world?s agricultural products. The majority of people?s livelihood in India depends on agriculture and its allied sectors. According to an economics survey in the agricultural year of 2019-2020, India is estimated to have produced around 292 million tonnes of food grain. The share of agriculture in India?s GDP is 19.9%. Even though India is an active participant in global agricultural trade, the total agricultural product export is only 2.5%. Agricultural produce is easily perishable and the quality gets affected which will then affect their market value. To meet the future food demands, agricultural produce must be able to store for a longer amount of time for round the year availability. The traditional food storage practices cannot satisfy that condition. These perishables need a proper cold supply chain to increase the shelf life. In this paper performance of a Parabolic Trough Collector Integrated Vapor Absorption Refrigeration system was developed and studied. Renewable integrated cold storage would open door to the sustainable energy future.

“…They discovered that the improve in thermal efficiency and melting rate until the full melting of the PCM, paraffin wax, at higher power levels. The various geometries of heat sink with different base plate materials, uniform fin width heat sinks with phase change material and double base plate heat sink [13,14].The outcome of the base plate on the heat transfer efficiency of heat sinks also investigated. The experimental outcome are higher compared to the CFD findings.…”

Experimental research demonstrates the performance of electronic devices on plate fin heat sinks in order to guarantee that operating temperatures are kept as low as possible for reliability. Paraffin wax (PCM) is a substance that is used to store energy and the aluminum plate fin cavity base is chosen as a Thermal Conductivity Enhancer (TCEs). The effects of PCM material (Phase shift material), cavity form base (Rectangular, Triangular, Concave and Convex) with PCM, Reynolds number (Re= 4000-20000) on heat transfer effectiveness of plate fin heat sinks were experimentally explored in this research. The thermal performance of concave base plate fin heat sink with PCM is increased up to 7.8% compared to other cavity base heat sinks.
