This paper introduces a new chemically-assisted mechanical refrigeration system that combines the advantages of the vapor compression, vapor absorption, and refrigeration/solvent resorption systems. Principles of the new system are presented and the search for suitable refrigerant/solvent pairs for the system is discussed. The feasibility of the proposed system has been verified by a sample cal...
The aim of reviewing information was characterizing in the labor factor using refrigeration technology is and their impact on environment. development industry occurred thanks to progress towards coolants. most important aspect refrigerators health human life, atmosphere. By caring for health, European Union achieves legal rights. Research thermodynamic factors pose a wide field work many scien...
Natural gas is often associated with nitrogen and heavy compounds. The Heavy components in the natural gas not only can feed downstream units, owing to the low temperature process may be formed solid as well. Therefore, heavy components separation can be a necessity and produce useful products. Virtually, all natural gases are containing nitrogen that would lower the heating value of natural ...
Improvement of simple and regenerative gas turbine using simple and ejector-absorption refrigeration
The exhaust gases of gas turbine power plant carry a significant amount of thermal energy that is usually expelled to the atmosphere this causes a reduction in net work and efficiency of gas turbine. On the other hand, the generated power and efficiency of gas turbine plants depend largely on the temperature of the inlet air, So that they both increase as the inlet air temperature decreases. Th...

a refrigeration cycle is a chain of various pieces of equipment including compressors, condensers, evaporators, and expansion devices each of which takes on a particular thermodynamic process duty in the cycle that eventually results in the production of the required refrigeration. the results of optimized mixed refrigerant cycles (mrcs) in part i show that the configuration of mrc is an effect...
Thermal-driven refrigeration systems have attracted increasing research and development interest in recent years. These systems do not cause ozone depletion and can reduce demand on electricity. The main objective of this work is to perform theoretical analyses of a thermal-driven refrigeration system using a new sorbent-sorptive pair as the working pair. The active component of sorbent is sodi...
This paper is a study of the ventilation, cooling and refrigeration system design of the Mindola copper mine in Zambia. The challenges that were addressed varied from the restrictions imposed by an ageing infrastructure to the requirement for increasing the annual production rate, coupled to the introduction of a higher level of mechanization while maintaining acceptable conditions and limiting...
A vapor jet refrigeration system (VJRS) is an alternative to the conventional mechanically driven vapor-compression refrigeration system. The VJRS utilizes supersonic ejector as thermal compressor and has the potential to reduce energy consumption and utilize low grade energy for driving the refrigeration systems. In the present study, the performance characteristics of VJRS ejectors with R134a...
