Enhancement in the COP of Thermoelectric Cooler Used for Cooling of Small Electronic Circuits
Abstract: Amidst growing environment concern, the need for alternative methods of cooling is on the rise, demanding higher intervention of technological advances. Conventional cooling systems working on CFC refrigerant pose threat to environment. The present work deals with performance investigation of thermoelectric cooler based on Peltier effect. Air cooling and water cooling systems are studied involving several parameter modifications. From the experimental work it is evident that optimum cooling is achieved …

Energy Efficient for Heat Exchanger, Refrigeration and Air Conditioning
Abstract: Scientifically, it is difficult to predict the relationship between global temperature and greenhouse gas (GHG) concentrations. The climate system contains many processes that will change if warming occurs. Critical processes include heat transfer by winds and tides, the hydrological cycle involving evaporation, precipitation, runoff and groundwater and the formation of clouds, snow, and ice, all of which display enormous natural variability. The equipment and infrastructure for energy supply and use …

Effect of Blanching on the Quality of Frozen Product of Carrot
Abstract: Carrot is one of the important root vegetables rich in bioactive compounds. The consumption of carrot and its products is increasing steadily due to its recognition as an important source of natural antioxidants having anticancer activity. Blanching is scalding the vegetables in water or in steam for a short time. The influences of blanching on the frozen product of carrots were investigated to determine the quality and shelf life of …

A Review Paper on Performance Evaluation and Enhancement of Cooling Tower
Abstract: Abstract Cooling towers are commonly used to reject heat from condenser water, heat exchanger, and other processing equipment. A cooling tower cools the hot water by a combination of heat and mass transfer. Energy and mass transfer through cooling tower play significant roles in cooling water temperature. Specifically, the work aims to conduct a detailed analysis of the heat and mass transfer processes in a natural draft wet cooling tower, …
