Evolutionary Diffusion Optimization, Part II: Performance Assessment

Compact, Low Temperature Refrigeration of Microprocessors

A compact, two-stage R-404A / R-508b cascade refrigeration system designed for interface with a high-performance microprocessor is under development. Such a system, designed to remove 100 W at –70 °C, can avoid the high cost of deep cryogenic cooling. Because thermal interface design is critical in maintaining low chip temperatures, a compact, microchannel evaporator is used. A chemically micro...

Exergoeconomic Assessment of Solar Absorption and Absorption-Compression Hybrid Refrigeration in Building Cooling

The paper mainly deals with the match of solar refrigeration, i.e., solar/natural gas-driven absorption chiller (SNGDAC), solar vapor compression–absorption integrated refrigeration system with parallel configuration (SVCAIRSPC), and solar absorption-subcooled compression hybrid cooling system (SASCHCS), and building cooling based on the exergoeconomics. Three types of building cooling are cons...

Mathematical Model of a Vapour Absorption Refrigeration Unit

By means of carefully devised assumptions, a simple linear model is presented for an absorption refrigeration unit employing either water-lithium bromide or ammonia-water refrigerant-absorbent pairs. Absorption systems are an alternative to vapour compression systems by being thermally activated. Such heat energy may come from the sun or even from hot exhaust gases from a particular engineering...

Study on Refrigeration System Designed for Low Temperature

In this paper study on refrigeration system designed for low temperature which has Zero-Ozone depleting point better heat transfer characteristic gives greater refrigerant effect. In this paper we study the main function part like compressor, evaporator, refrigerant, fan and motor, Technical Details of the components. Energy is the primary and most universal measure of all kind of work by human...
