The energy demand of industries accounts for about 30–35% world yearly consumption, a relevant percentage is due to the need heating and cooling demand. Solar technologies can be integrated in industrial processes reduce fossil fuels consumption as well related greenhouse gas emissions. This paper reports experimental analysis novel hybrid sorption-compression chiller refrigeration purposes cas...

Thermal energy storage (TES) for a cooling plant is crucial resource load flexibility. Traditionally, simple, heuristic control approaches, such as the priority which charges TES during nighttime and discharges daytime, have been widely used in practice, shown reasonable performance past benefiting both grid end-users buildings district systems. However, increasing penetration of renewables cha...

Heat driven cooling technologies like vapour absorption and adsorption systems are environmentally friendly. Use of thermal compression in these systems saves precious and fast-depleting fossil fuel resources. Solar energy and low-grade waste heat can be effectively used in running these cooling systems. The present work focuses on the development of a solar-powered vapour adsorption based cool...

This study was conducted to determine the prevalence of Salmonellae contamination of chicken carcasses in slaughterhouses in central Iran (Yazd province). 435 samples were obtained from liver, breast— before and after chilling—and bacteriological and serological examinations were done. The results showed that the rate of contamination of liver, breast meat—before and after chiller—were 8.1, 18....

Use of multi-plant extracts against infectious diseases is increasing in rural Tanzania. The study evaluated this ethnomedicinal practice by using mixed root extracts of Carisa edulis, Ximenia caffra, Harrisonia abyssinica and Euclea natalensis against single extracts of the same plants. Disc diffusion assay and Tube dilution techniques were used to compare bioactivity of plant extracts in-vitr...

The energy saving is becoming an important topic also in the food industry. For this reason, it is important to use multi-energy systems to produce hot water for processes and space heating. The application considered in this paper, which concerns a chocolate factory, focuses on the hot water production through a multi-source storage tank. The water inside the tank is heated by four solar panel...

This paper presents the development and use of benchmarking grey-box models for detection diagnosis multiple-dependent faults (MDFDD) a water-cooled centrifugal chiller. Models are developed using data recorded by Building Automation System (BAS) from central cooling plant an institutional building. The forward residual-based fault model identifies symptom, when difference between measured valu...
