Fault detection and diagnosis (FDD) systems enable high cost savings energy that could have economic environmental impact. This study aims to develop validate a data-driven FDD system for chiller. The uses historical operation data capture quantitative correlations among variables. evaluated the effectiveness robustness of eight classification methods based on experimental chiller (the ASHRAE 1...

based on existence of the chromite deposits in the sistan and baluchestan province in iran, and also various applications of chromite in different industries, it is expected that the establishment of chromite processing plant is required in the erelong. the geographical location of a processing plant can have a strong influence on the success of an industrial venture. the processing plant site ...

Background: Defensin peptide isolated from plants are often heterogeneous in length, sequence and structure, but they are mostly small, cationic and amphipathic. Plant defensins exhibit broad-spectrum antibacterial and antifungal activities against Gram-positive and Gram-negative bacteria, fungi and etc. Plant defensins also play an important role in innate immunity, such as he...

In today’s dynamic market, organizations must be adaptive to market fluctuations. In addition, studies show that material-handling cost makes up between 20 and 50 percent of the total operating cost. Therefore, this paper considers the problem of arranging and rearranging, when there are changes in product mix and demand, manufacturing facilities such that the sum of material handling and rearr...

• Mechanical subcooling increases the COP of CO 2 systems at high outdoor temperature. The gas cooler pressure plants can be reduced with degree. Optimum degree and optimum cooling capacity subcooler are found. Dedicated Subcooling (DMS) is one most investigated effective strategies applied to increase performance commercial refrigeration in transcritical operation. Further benefits obtained by...

Abstract The organic Rankine cycle (ORC) power plant is derived from a centrifugal chiller air conditioning system as an alternative to diesel replacement modular due its low cost compared ORC’s manufacture. Biomass used heat source for the utilize vast amount of biomass in Indonesia. Research performed by designing ORC with that produces around 200 kWe. Simulation done Microsoft Excel and Refe...

Biofuels have become a source of renewable energy to offset the use fossil fuels and meet demand for electricity, heat, cooling in industrial sector. This study aims (a) develop simulation trigeneration system based on gas turbine cycle an absorption chiller unit, using biomass syngas from spent coffee grounds (SCGs) replace conventional currently supplying requirements instant plant located Gu...
