Chilled-water cooling systems used in the chemical processing, petroleum manufacturing, and power generation industries remain fertile ground for electrical energy savings. This is in spite of the lack of attention given to industrial cooling by energy auditors and rebate program designers. This article discusses the large energy savings that can be achieved through hardware and operational imp...

Cooling towers are a source of Legionnaires' disease. It is important from a public health perspective to survey industrial cooling towers for the presence of Legionella. Prospective surveillance of the extent of Legionella pollution was conducted at factories in Shijiazhuang, China between March 2011 and September 2012. Overall, 35.7% of 255 industrial cooling tower water samples showed Legion...

Legionella pneumophila serogroup 1 causes Legionnaires' disease. Water systems contaminated with Legionella are the implicated sources of Legionnaires' disease. This study analyzed L. pneumophila serogroup 1 strains in China using sequence-based typing. Strains were isolated from cooling towers (n = 96), hot springs (n = 42), and potable water systems (n = 26). Isolates from cooling towers, hot...

In this manuscript we present the design and construction of a pilot system that incorporates both a heat exchanger component and a cooling tower add-on. This prototype was constructed in order to simulate real industrial open recirculating cooling systems. Heat exchanger planning was realized using mass and energy balance. The application of mass balance was realized under permanent (static) c...

A steady-state model for a centralized cooling system is developed to enable proper provisioning of cooling resources in capital intensive projects such as data centers. The model resolves the energy equations for a cooling tower and a centralized water-cooled chiller simultaneously. It requires inputs that are readily available to the design engineer. The user inputs are the ambient conditions...

Abstract The paper proposes a computational method to study and test the relationship between shape performance for built environment, sustaining use of smart geometry support design operation. A comprehensive working principles hyperboloidical cooling tower is presented. case in Marghera (Venice), 1938 explored.
