...V. Baiju; C. Muraleedharan The refrigerants used in the present study are methanol of 99.99% purity and R134a. All the properties of the refrigerants used in the paper are taken from Refprop (version 8) software. The activated carbon of 1.5 kg of particle diameter of 0.25 mm is used...

...Jingming Dong; D. A. Pounds; P. Cheng; H. B. Ma A steam ejector refrigeration system with a movable primary nozzle was developed in order to determine the nozzle exit position (NXP) effect on the coefficient of performance (COP). Experimental results show that there exists an optimum NXP...

...Vijayaraghavan S. Chakravarthy; Ramesh K. Shah; G. Venkatarathnam In this paper, a comprehensive review of the principles of different refrigeration methods covering the temperature range from 4 K to 300 K is presented. The methods covered are based on steady state systems, such as the Carnot cycle...

...P. Zhang; Z. W. Ma; R. Z. Wang The application of phase change material slurry to the refrigeration and air conditioning system opens a new way for energy saving and reduction of the quantity of refrigerant in the system involved because it can serve as both the energy storage...

... conditions are subject to a number of constraints, including energy consumption, controllability, and the volume or size of the package. Calculations indicate that the only possible approach to meeting this heat flux condition, while maintaining the chip temperature below 65 ° C , is to utilize refrigeration...
