"Evaporative-cooling equipment is selected to provide a fluid (usually water) to a system at a certain temperature and flow rate. If the temperature of the fluid delivered to a system (chiller) is higher than desired, the system will suffer increased wear and tear and usage. Decreasing leaving-water temperature by just 2°F can lower electricity expenditures by 6 percent.

Routine inspection and maintenance is paramount in achieving desired temperature and flow rate, and it plays an important role in extend operating life

"Most light-commercial HVAC products are designed for a useful life of 15 to 20 years. During that time, however, the reliability and cost-effectiveness of operation often is dictated by factors beyond the manufacturer’s control. At the same time, newer, more efficient HVAC products often can reduce maintenance and utility costs. When it comes to deciding whether to repair or replace an older rooftop unit, it is important to consider a number of factors, including current condition, age, efficiency, maintenance/repair history, and associated utility costs. This article will discuss the process of making an informed decision."

"The symptoms are familiar: hot and cold complaints, higher-than-expected costs, etc. Here’s a look at how the retrocommissioning process should work to tackle these and other developments for your facility."

Establishing Proper Pressure Drop for Feedwater Flow Control Valves

Power Magazine, Feb. 2014, by S. Zaheer Akhtar, PE.
http://www.powermag.com/establishing-proper-pressure-drop-for-feedwater-flow-control-valves/

"Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, conventional methods used for establishing control valve pressure drop cannot be used at face value without reviewing all plant operating scenarios."
