Four different double-compression CO2 transcritical refrigeration cycles are studied: double-compression external intercooler cycle (DCEI), double-compression external intercooler cycle with an expander (DCEIE), double-compression flash intercooler cycle (DCFI), double-compression flash intercooler cycle with an expander (DCFIE). The results showed that the optimum gas cooler pressure and optim...
Increasingly, military and civilian applications of electronics require extremely high-heat fluxes on the order of 1000 W /cm2. Thermal management solutions for these severe operating 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 f...

Refrigerator is one of the home appliance utilizing mechanical vapour compression cycle in it process. Performance of the system becomes main issue and many researches are still ongoing to evaluate and improve efficiency of the system. Therefore, this paper presents the development process of refrigerator test rig and performance evaluation of a domestic refrigerator that has been used in Malay...
The vortex tube is a structurally simple device with no moving parts that is capable of separating a highpressure flow into two lower pressure flows with different energies, usually manifested as a difference in temperatures. The vortex tube is relatively inefficient as a stand-alone cooling device but it may become an important component of a refrigeration system when employed as an alternativ...
Refrigeration is one way to maintain the temperature of a material or room at lower level than ambient conditions around it by absorbing heat from room. The refrigeration system that widely used today for industrial purposes use vapor compression cycle, where in this cycle components has an important role compressor. Over time, performance compressor will decrease, so affect absorption process ...
The coefficient of performance (COP) for a gas refrigeration cycle was estimated using Matlab/Simulink and fuzzy logic. A model the developed, output compared to theoretical data. Additionally, logic used estimate COP arbitrary low- high-pressure levels. Simulation results were develop multi-input-multi-output (MIMO) Takagi-Sugeno-Kang (TSK)-based model. Both MIMO found be very well correlated ...
