Solar collector (Air heater) has low thermal efficiency due to the low thermal conductivity between Air and absorber plate. So there is a need to enhance the thermal conductivity between air and absorber plate. This leads higher temperature to absorber plate and hence maximum thermal losses occurs to environment .It can be made possible by creating artificial roughness on absorber plate .There ...

Fish as a source of animal protein is fishery commodity that prone to quality deterioration and spoilage after the fish caught, so it needs fast, precise correct handling keep its in hands consumers. There for necessary have process extends durability through drying. One drying alternative use Solar Air Heater with an Ultra Violet (UV) Dryer house by making building made transparent material fu...

Evacuated tube solar water heater systems are widely used in China due to their high thermal efficiency, simple construction requirements, and low manufacturing costs. CPC evacuated tube solar water heaters with a geometrical concentration ratio C of less than one are rare. A comparison of the experimental rig of evacuated tube solar water heater systems with and without a mini-CPC reflector wa...

To minimize environmental impact and CO2 production associated with air-conditioning system operation, it is reasonable to evaluate the prospects of a clean energy source. Solar energy can drive an absorption chiller in order to satisfy the cooling needs of buildings. The objective of this work is to build a simulation environment that can evaluate accurately the energy consumption of an air co...

TThe present paper evaluates the plan of combustion air pre-heater installation on the fired heater from thermodynamics and thermos-economics point of view. As a real case study, one of the fired heaters (H_101) of Distillation unit in Tehran Oil Refinery, Iran, is intended. With applying an air pre-heater in this study, flue gases temperature falls down from 430 ºC to 200ºCand combustion a...

Due to the depletion of fossil fuel reserves, it is now more important than ever explore and use alternate forms energy. “Solar energy a promising long-term solution that can meet world's needs. essential we energy-related solutions as soon possible. Solar solution. Artificially roughened solar air heaters perform better smooth ones under same operating conditions. However, artificial roughness...
