Industrial Utility Efficiency    

Technology

AHR EXPO is an incredible, powerhouse of a show for all involved in the cooling system industry. Since 1930, the Show has provided a unique forum for the entire HVACR industry, including OEMs; engineers; contractors; manufacturers; distributors; commercial, industrial and institutional facility operators.

Chillers

Manufacturers are under continual pressure to control costs without affecting operations or worker comfort and safety. Because energy ranks as one of the largest operating expenses, improving energy efficiency of mechanical cooling systems is one of the best ways to reduce operating costs. In a typical water-cooled chiller plant, the chiller itself accounts for most of the energy consumption. That’s why improving chiller efficiency is critical to controlling operating costs.

Cooling Towers

Cooling tower customers want product innovations that can give them a greater amount of cooling for the energy used. In this age of shrinking operational budgets, they also seek ways to reduce installation and maintenance costs. These customer needs cut across industry lines, whether for light industrial or heating, ventilation and air conditioning (HVAC) applications, or for power and process cooling operations.

Fluid Coolers

There are six basic types of cooling systems that you can choose from to meet the cooling needs of your load. Each one has its strengths and weaknesses. This article was written to identify the different types of cooling systems and identify their strengths and weaknesses so that you can make an informed choice based on your needs.

Dry Coolers

This article contains pieces from an audit report developed for a fish processing plant located in Yangon, Myanmar. is located in the Thinbawgin Ward of Dawbon Township in Yangon, Myanmar.  The objective is to show factories the information they may want to have gathered on their refrigeration systems and supporting cooling systems.

Water Filtration

Water treatment professionals understand that if applied correctly, solid-form products can be just as effective of a method to protect cooling and heating systems from corrosion and scale as their liquid counterparts. And with the additional sustainability, safety, ease of use, and shipping cost benefits of solids, hundreds of facilities are transitioning to these products each year world-wide.

Heat Exchangers

We are certain it comes as no surprise to the readership of this journal that a third of the total energy end use for commercial buildings in the U.S. is consumed by HVAC (DOE 2008). Chillers are usually the single largest individual user of electricity in commercial and institutional HVAC facilities. Maintenance and engineering managers have three primary options to improving chiller performance: replacement, control strategies and maintenance. As chillers are required to reject heat to complete the vapor-compression cycle, a condenser heat exchanger is used which allows heat to migrate from the refrigerant gas to either water or air. Heat transfer has the greatest single effect on chiller performance.

Cooling Controls

Chrysler’s Technology Center (CTC), located in Auburn Hills, MI, is home to some fourteen thousand employees responsible for keeping the automotive giant in motion. Completed in 1991, the complex is essentially a small city, encompassing 5.3 million square feet situated on over 500 acres. In addition to corporate offices, the facility houses a full laboratory level of various wind tunnels with thermal testing capabilities, a 1.8-mile evaluation road, a noise/vibration facility, an electromagnetic compatibility center, an environmental test center (able to create rain, snow and extreme temperatures), and a pilot production plant.
Held September 16-19, 2018 in Chicago, the first-ever event drew 750 attendees who came together to learn and share ideas about the countless ways to achieve efficiencies with compressed air, blower, vacuum and cooling systems – and in the process – save energy and improve profitability.
Penn State Health Milton S. Hershey Medical Center, Hershey Pa., is all about energy and resource efficiencies, which is why it adopted a new approach to managing its chilled water operation. The approach, which revolves around a software and analytics platform used to optimize three chiller plants in addition to various equipment upgrades, has allowed it to save 4.16 GWh/yr in electrical energy consumption – and shave $300,000 off of its annual electrical costs. With an incentive from the local utility of $415,799, the multi-phased initiative achieved a payback of 4.3 years. 
The NPE 2018 International Plastics Showcase was held at the Orange County Convention Center in Orlando, Florida, May 7-11. Setting all-time records, the Show attracted 2,180 exhibitors — including Chiller & Cooling Best Practices and Compressed Air Best Practices® Magazines! Over 1,200,000 square feet of exhibition space was used, breaking the all-time NPE record. Held once every three years, NPE 2018 registered attendance was 56,000.
Rush University Medical Center (RUMC) is Chicago's second-largest hospital with multi-story buildings that dominate the city's medical district. But that prestigious location posed problems when RUMC's 11-story Professional Building 2 needed to replace two aging centrifugal chillers. It appeared the only alternative was to move a crane down a crowded street to lower new chillers through the roof. But some simple surgery made it possible for Smardt split-shell chillers with Danfoss Turbocor® compressors to simply take an elevator up to the penthouse mechanical room, a solution that cut installation costs while boosting energy savings.

In this age of shrinking operational budgets, they also seek ways to reduce installation and maintenance costs. These customer needs cut across industry lines, whether for light industrial or heating, ventilation and air conditioning (HVAC) applications, or for power and process cooling operations.
Data center power consumption is on the rise, increasing 56 percent worldwide and 36 percent in the U.S. from 2005-2010. These substantial energy demands come at a price, and controlling operational costs in data centers has been a persistent challenge. IT systems are designed to ramp up and down based on a businesses’ use, yet cooling systems in data centers were not previously designed to do that.
The ComEd® Energy Efficiency Program offers incentives to help facilities save money by improving the efficiency of their equipment. Industries can receive standard cash incentives for common energy efficiency improvements or custom cash incentives for making improvements not included in the standard program.
An airside economizer is typically used on a packaged rooftop or tied to an indoor AHU, allowing filtered outside air into the space when outdoor temperatures drop below 55°F (12 °C) (the common supply air temperature of indoor spaces) thus alleviating the need for the refrigeration cycle to be running. Interior space is being cooled yet the refrigeration system is not running, hence the name Free Cooling.
Commercial buildings in the United States will be looking to replace centrifugal chillers as many are near or past their median replacement life of 25 years. This becomes apparent when you consider nearly half of all commercial buildings were constructed before 1980 according to data from the U.S. Energy Information Administration. The same can be said of buildings on American college campuses, which according to the same data, more than half of which were built before 1990. Bottom line — if you’re a commercial building owner or a facility manager/director in the United States, you may need to replace a chiller.
One of the most important steps in the mold making process is a consistent and proper cooling cycle. This is due to the fact cooling rates can have a significant influence on the overall quality of the finished item. The cooling cycle must remain consistent throughout the entire production run to ensure all items are equal in quality.
