Optimization of Water - Cooled Chiller – Cooling Tower Combinations
Water-cooled chiller systems have typically been designed around entering condenser water temperatures of 85°F with a Optimization of Water Cooled Chiller – Cooling Tower Combinations The warm water leaving the chilled water coils is pumped to the evaporator of the chiller, where the unwanted heat from the building is transferred by the latent heat of vaporization of the refrigerant. The compre...
متن کاملMicrobiology of broiler carcasses and chemistry of chiller water as affected by water reuse.
A study was conducted to determine the effects of treating and reusing poultry chiller water in a commercial poultry processing facility. Broiler carcasses and chiller water were obtained from a commercial processing facility which had recently installed a TOMCO Pathogen Management System to recycle water in sections 2 and 3 of two 3-compartment chillers. In this system, reused water is blended...
متن کاملIntegrated Chiller System Reduce Building Operation and Maintenance Costs in Cold Climates
Although water-cooled chillers are more energy efficient than air-cooled chillers, a majority of chilled water systems use air-cooled chillers. In cold weather climates, air-cooled chillers are capable of functioning in low ambient temperatures with few operational concerns, where as water-cooled chiller systems must be equipped to prevent cooling tower freezing. The integrated chiller system a...
متن کاملMaintenance of Water Distribution Systems
The efficient long term management of large-scale public funded assets is an area of growing importance. Ageing infrastructure, growth, and limited capital all result in the need for more robust and rigorous methodology to prioritise rehabilitation and renewal decisions and more importantly, to forecast future expenditure requirements. The overall objective of this research is to develop a Baye...
متن کاملEnhancement of bactericidal effects of sodium hypochlorite in chiller water with food additive grade calcium hydroxide
An alkaline agent, namely food additive grade calcium hydroxide (FdCa(OH)2) in solution at 0.17%, was evaluated for its bactericidal efficacies in chiller water with sodium hypochlorite (NaOCl) at a concentration of 200 ppm total residual chlorine. Without organic material presence, NaOCl could inactivate Salmonella Infantis and Escherichia coli within 5 sec, but in the presence of fetal bovine...
