Shell-and-tube latent heat thermal energy storage units employ phase change materials to store and release at a nearly constant temperature, deliver high effectiveness of transfer, as well charging/discharging power. Even though many studies have investigated the material formulation, transfer through simulation, experimental studies, there is limited research dedicated unit design methodology....

Two experiments (EXP), utilizing the skin attachment model (SAM), were conducted to determine the bactericidal activity of six potential carcass disinfectants [EXP 1: 20, 400, and 800 ppm sodium hypochlorite; EXP 2: 5% acetic acid (AA), 8% trisodium phosphate (TSP), and 1% sodium metabisulfite (SS)] during simulated scalder (50 C for 2 min), chiller (0 C for 60 min), or post-process dip (23 C f...

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....

Recent world events and geopolitics have brought the vulnerability of critical infrastructure to cyberattacks forefront. While there has been considerable attention attacks on Information Technology (IT) systems, such as data theft ransomware, vulnerabilities dangers posed by industrial control systems (ICS) received significantly less attention. What is very different that can be made do thing...

An appropriate design of a chiller plant is crucial to guarantee highly performing solutions. However, several variables, such as type systems, total cooling capacity, and hydraulic arrangement, need be considered. On the one hand, at present, different technical criteria for selecting most suitable variables are available. Studies that corroborate influence over operational missing. In order f...

Investigating the pool boiling process in absorption chiller generator by studying valid parameters may enhance chiller?s COP. In present study, transient 2-D numerical modelling of LiBr/H2O solution was carried out using two-phase Eulerian-Eulerian approach, extended Rensselaer Polytechnic Institute model and renormalization group k-? turbulence model. The applied on three types bare, notched ...

As the phase-out of chlorofluorocarbons (CFC's) approaches, there is a current need for the development of new vapor compression chillers which can operate with non-CFC refrigerants while still maintaining high operating efficiencies. Redesign of the traditional flooded evaporator used in refrigeration chillers so as to incorporate a spray evaporation capability offers both a potential for incr...
