A major problems in the operation of laptop computers is overheating since it can affect the performance and stability, sometimes leading to system crash and hardware fatality. The objective of this work was to study the thermal behavior inside a laptop computer and to test the effectiveness of aproposed cooling method to overcome overheating problem. The proposed cooling system contained a the...
In air conditioning cooling systems, especially in regions with extremely hot weather, reducing power consumption and improving performance are key concerns. the summer, system's efficiency drastically declines its use of electricity significantly rises. This article analysis an experimental theoretical study to improve evaporative condensers used using cooled air. The paper mainly focuses on e...
In Sliding Vane Rotary Compressors, as well as in most of positive displacement machines, the oil is injected to accomplish sealing and lubrication purposes. However, the oil injection could produce an additional outcome during the compression phase with a great saving potential from the energetic point of view. Being the air inside the cell at a higher temperature than the oil injected, a cool...
The present paper is a numerical and experimental comparative study of hermetic and semi-hermetic reciprocating compressors working with carbon dioxide as fluid refrigerant against the conventional R134a hermetic compressors. When cooling conditions for one-stage compressor type (i.e., evaporation temperatures between 7.2oC and –10oC) have been considered, the numerical and experimental results...
one way to increase the shelf life of agriculture products is using of controlled atmosphere storages. in order to obtain the controlled gas components, an equipped cold store with cooling system and atmosphere controller system designed and constructed. the injection of co2, o2 and n2 were controlled automatically into the store by programable logic control (plc). the store was a laboratory re...
• A new hybrid humidification–dehumidification and air conditioning system is proposed and investigated. • The proposed system keeps the function of the air conditioning system and uses it in water desalination. • The effects of system operating parameters on system performance were evaluated and correlated. a b s t r a c t a r t i c l e i n f o An experimental study of the performance of a hyb...
This work investigates a novel heat-driven multi-stage thermoacoustic cooler that can satisfy cooling requirements in the applications of natural gas liquefaction and high-temperature superconductivity. The proposed system consists compressor, multiple units (engines coolers) coupled by piston-cylinder assemblies. acoustic power input compressor is successively multiplied engine units, amplifie...
The main objective of this investigation was to design and investigate a radiant panel cooling system on small scale building type (office) under the central Sudan climatic conditions so as to explore the benefits of radiant cooling systems over conventional air conditioning systems (Variable air volume systems). Transient heat conduction of building (finite difference method) was used to evalu...
