Air Conditioning Systems: A Challenge to Climate Change
Abstract: Abstract Demand for air conditioning is growing speedily especially in developing countries (South-East Asia) due to income growth, population growth and the need for better comfort level to protect from heat exposures. Only few models estimated future air conditioning use in major areas with increased heat level. However, worldwide and local studies concerning climate variables with air conditioning alone are lacking when facing additional heat due to climate change. More …

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, …

Ecological Optimization of Irreversible Carnot Magnetic Refrigerator
Abstract: Abstract An irreversible Carnot Cycle model is analyzed, with the help of various irreversibility factors, such as finite time analysis and heat leakage. In which, several important performance parameters, such as the cooling rate, coefficient of performance (COP), power input, exergy output rate, entropy generation rate, and ecological function are derived, with taking the assumptions like, heat leakage and the time of the isothermal processes in account. Ecological optimization factor …
