in this study,the effect of ozonated water(0.2, 0.5, and 1 ppm) with different exposure times (5,10, and 15 min) for control of staphylococcus aureus , escherichia coli and total counts in poultry carcass, on chiller water in slaughter house were investigated. for this purpose, control samples passed chiller water(without ozone) for (5,10, and 15 min) .other examples also treated (5, 10 , and 1...

ABSTR&CT Seven brickmaking clays from various geological horizons have been studied by differential thermal and X-ray methods. The minerals detected included kaolinite, illite, montmorillonite, chlorite, swelling chlorite, calcite and quartz, and rough estimates were made of the quantities present. For the same clays, deformation-under-load was measured at four different heating rates, and stre...

For many countries, increasing energy efficiency and reducing greenhouse gas emissions are key countermeasures to cope with the energy crisis and climate change. Of the various heating equipment such as heat pumps, gas-fired boilers, oil-fired boilers, or electric boilers, heat pumps are widely adopted for space heating, water heating, and process heating by households, business, and industry d...

More than half the energy to run a data center can be consumed by vapor-compression equipment that cools the center. To reduce consumption and recycle otherwise wasted thermal energy, this paper proposes an alternative cooling architecture that is heat driven and leads to a more efficient data center in terms of power usage effectiveness (PUE). The primary thermal source is waste heat produced ...

Chiller plants are the most energy consuming system during summer season in residential, commercial and hospital buildings. The highly variable cooling demand of buildings connected to a hybrid chiller plant included absorption vapor compression chillers achieve higher efficiencies is one important issues. Cooling load sharing strategies apply water flow have significant impact on consumption c...

We developed an appropriate Absorption chiller to "Solar cooling system" in 2010. In addition, we added the improvement to the machine. "Solar cooling system" can be easily constructed with the machine. and, we constructed the demonstration plant, and verified the utility

Buildings account for almost 40% of global energy consumption. Due to the high consumption chilled water plants, various studies have optimized chiller loading in plants with multiple chillers conservation. However, few dual-temperature even though better efficiency could be achieved than that typical single-temperature plants. This paper proposes two optimal control strategies strategy B and C...

Adsorption refrigeration, as a renewable cooling method, has received more attention in the last few years. The interest this technology comes especially from developing and tropical countries, where demand for increases every year due to economy population growth. Based on scenario, work aims develop numerical model of an adsorption chiller driven with solar energy, which can be used optimize ...
