An analytical investigation has been conducted on the performance of an adsorption chiller driven by solar collector panel for the climatic condition of Dhaka. A set of mathematical model and simulation technique are exploited to investigate the system performances of solar driven basic adsorption chiller with silica gel-water as adsorbent/adsorbate pair. For base run condition, at least 13 col...

A Model Predictive Control (MPC) implementation was developed for a university campus chilled water plant. The plant includes three water-cooled chillers and a two million gallon chilled water storage tank. The tank is charged during the night to minimize on-peak electricity consumption and take advantage of the lower ambient wet bulb temperature. A detailed model of the chilled water plant and...

Abstract A data centre is a facility where it hosts the server systems, computer and its associated components such as cooling units, redundancy power supplies storage systems. Data centres are very energy-demanding sector. Centre Dynamics magazine forecasts that by 2025, Centres will consume more than 2% of global electricity supply. Due to this forecast, become vital reduce energy consumption...

Campylobacter spp. cause foodborne illnesses in humans primarily through the consumption of contaminated chicken. The aim of this study was to evaluate the United States Department of Agriculture's (USDA) recommended methodology, protocol MLG 41.02, for the isolation, identification and direct plate counting of Campylobacter jejuni and C. coli samples from the broiler slaughtering process. A pl...

A mathematical model describing the behaviors of current commercialized silica gel-water adsorption chillers is presented in this study. Comparing with the previous study, this model comprises (i) a realistic representation of the thermal mass of the associated piping materials and fins; (ii) a distributed modeling of the reactor bed for the sorption processes. The model is demonstrated on a tw...

Growing concerns about the global warming impact of refrigerants used in HVAC&R equipment are driving development and evaluation of alternative refrigerants with lower global warming potentials (GWPs). The Air Conditioning, Heating, and Refrigeration Institute (AHRI) recently coordinated the Low-GWP Alternative Refrigerant Evaluation Program (AREP) in which commercial, university, and governmen...

Over the last few decades, total energy consumption has increased while resources remain limited. Energy demand management is crucial for this reason. To solve problem, predicting and forecasting water-cooled chiller power using machine learning deep are presented. The prediction models adopted thermodynamic model multi-layer perceptron (MLP), time-series MLP, one-dimensional convolutional neur...
