However, the risk of developing unstable pressure control can only be reduced – it cannot be eliminated.

Different Approach Measures Flow Rate Instead of using two differential pressure transmitters, a flow meter can be used as the second pump control input. The flow meter has the capability of measuring the output of one chiller plant and will not directly interfere with the pressure control of the other chiller plant. A flow meter that has no moving parts is preferred because it provides a smooth and steady signal. The pump

As might be expected with a new control method, Citizens experienced a learning curve when implementing flow meter control. According to Joe Ray, senior operator for Citizens Thermal, however, “The flow meter control method works very well. Citizens has spent time to train the operators on how to set the flow control and has developed enough confidence to start chillers remotely. Investment in a reliable control system and some cameras to get a remote view of the chiller assisted greatly in transitioning to a remote chiller start.” Ray adds that “chiller dispatching decisions are made at the operator level

IDEA2q10Digital.indd 19 4/7/10 2:03 PM Since we do not inject amines, we needed to ensure that the pH of the condensate would not erode or corrode the new condensate system piping. In reviewing different types of piping for condensate, it was noted immediately that we had to keep the temperature of the returning condensate below 200 degrees F in order to use a pipe that had a resistance to low pH for long-term use. The pipe we chose was a preinsulated PEX and polyethylene with an oxygen diffusion barrier rated at 204 F. Our specifications for the customers are that the condensate needs to be returned at temperatures between 140 F and 200 F. In addition there are some specifications related to the conductivity of the condensate to ensure water quality.

As a consequence, most boilers operating today have efficiencies that are less than 81 percent. Such low efficiencies have a significant impact on the country’s energy consumption, since approximately 40 percent of all the energy used in America is consumed in boilers. The importance of boilers in our energy mix, the volatility of energy costs and the increased emphasis on reducing carbon footprint have combined to heighten the urgency to improve boiler efficiency and emissions. This has spurred research and development toward the so-called “Super Boiler”: an ultra-high-efficiency, ultra-low-emissions compact gas-fired packaged boiler originally conceived of

Recognizing these various sources represented a substantial heat sink, Mortensen enlist- ed Benz Air Engineering Co. to design and incorporate a heat recovery system into the new boiler project. A pinch analysis of preheating boiler makeup and process water using boiler flue gas heat recovery was used to design a condensing heat exchanger. The resulting design (fig. 2) integrated the condensing heat exchanger into the boiler system, which, when combined with the control system, yielded some novel features that would result in efficiency exceeding 93 percent: l Installation of an additional heat exchanger between the makeup water and the feed water provided significant reduction in the needed Source: Del Monte Foods Modesto.

Get 16% energy savings by optimizing your chiller plant’s speed

District-cooling plants can cut their energy costs by as much as 16% by utilizing variable-speed drives (VSDs) on their centrifugal chillers. Although the chillers run at high loads, on average, the tower-water temperature and the plant load both fall as the outdoor temperatures fall. And tower-water temperature has a 200% to 500% greater impact on VSD savings than does chiller load. Get up to speed on the savings that VSD technology can offer your facility by contacting your local Johnson Controls ofﬁ ce.

IDEA2q10Digital.indd 62 4/2/10 4:32 PM ® LEED + Q: New and Improved Version 2.0: Where is it? District Energy A: Throughout 2009, IDEA worked closely with the U.S. Green Building Council (USGBC) to develop a new guidance document to address the specifics of applying the LEED guidelines Reporting to buildings that were connected to district energy. While there is an existing guidance document available and in From Reno: force today, this guidance is difficult to follow and does not address many of the Discussions reflect both system options available to district energy operators. In addition, it often puts district energy systems on an uneven and frustration and hope unfair playing field when compared to Tim Griffin, PE, LEED AP, IDEA USGBC Liaison building standalone systems. IDEA’s efforts last year ended in a much improved district energy guidance document that puts district energy on a level playing field. In fact, last quarter’s column (first quarter 2010, p. 62) highlights many of the improvements the new guidance document will have over the old. Unfortunately the document still has not been released. The original release date was anticipated to be October 2009, which would have paralleled the release of LEED 2009, the latest new and existing building rating system.

Allow me to explain: In these tough economic times when we are all looking to pinch pennies or stretch the few that we have, there may be opportunities to do so right before our eyes, but we miss them. One example is adding an adjustable-speed drive (ASD) to a pump or fan motor to reduce electrical consumption at part load. Varying the speed of a pump or fan takes advantage of the affinity laws where power is proportional to the cube of the shaft speed.

Baltimore-based global asset management firm Legg Mason moved into its new corporate headquarters in the Legg Mason Tower skyscraper in summer 2009. The sleek, modern and sustainable structure is part of the new Harbor East development that reflects the city’s waterfront urban revitalization and has redefined Baltimore’s downtown area. With views of the harbor and the surrounding prom- enade, the 24-story tower, designed by HKS Hill Glazier Studio with Beatty Harvey Coco Architects as the architect of record, and developed by H&S Properties Development Corp., stands 350-ft tall and is a customer of Veolia Energy’s Trigen Inner Harbor business unit. The 70-acre Harbor East neighborhood extends into Baltimore’s harbor, bridging the Inner Harbor and Fells Point. Legg Mason’s premier waterfront tower contains 660,000 gross sq ft of commercial
