This paper investigates the effects of subcooling the condenser outlet refrigerant in a compression refrigeration by an absorption refrigeration in an integrated refrigeration system from energy view point. For this purpose the thermodynamic system is analyzed, base on the mass and energy equation and also the effects of operating parameters such as prime mover, ambient temperature and evaporat...

in civil engineering concrete is a material combined of hydraulic cement, sand, gravel and water. gravel and sand compose 60 to 70 percent of concrete. these aggregates support compression force of concrete. cement paste acts as glue to stick grain together. in bushehr factories producing aggregates do not operate according to astm standards, so that fineness modulus (fm) of the produced sands ...

There are various methods of power generation such as combined cycle power plants. There are many variables in a power plant boiler unit, but the most important variables are Pressure and specially drum level that control system should be put it in the safe range. The purpose of this article is, modifying the oscillatory behavior of the drum level of Kerman combined cycle power plant and especi...
