A review on Design of Cascade Vapour compression Refrigeration System
Abstract: Cascade refrigeration system is an ultra-low temperature multi-stage refrigeration systems operating at ideal low temperatures ranging from -30°c to -100°c.Cascade system is a frigid system that adopts dual refrigerants having diverse boiling points, that escape through the medium of their particular frigid cycle and are combined by a cascade heat exchanger. Cascade refrigeration systems are used for obtaining faster cooling in a much lower time than the normal vapour compression …

Analysis of Combined Heating Cooling Power Plant
Abstract: Exergy analysis is a useful concept for ecology and sustainability because it can use as a common measure of resource quality along with quantity. The exergy of an energy form or a substance is a measure of its usefulness or work potential. Plant efficiency management in first instance is concerned with thermal efficiency. Ultimately plant wants to produce as much output for least expenditure of fuel. When plant efficiency deteriorates, …

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 …

Piezo-electrically driven Thermoacoustic Refrigerator
Abstract: Thermoacoustic refrigeration is an emerging field of technology. This technology uses sound waves to pump heat across a temperature gradient and the sound waves are produced using piezoelectric material. The main aim of this idea is to reduce the usage of harmful refrigerants which are great threat to the global warming. The study focuses technically on using the piezo-electric materials to get the desired refrigeration effect. Moreover, the added advantage …
