"When the efficiency of a facility’s plumbing and HVAC systems is maximized, building owners realize energy- and operational-cost savings. Optimal efficiency can be achieved through seasonal maintenance and best practices regarding water pumps."

HVAC Contractors Prepare for DOE Efficiency Mandates

"At the beginning of the year, the U.S. Department of Energy’s (DOE’s) minimum efficiency standards for residential air conditioners and heat pumps went into effect, dividing the country into three regions — North, South, and Southwest. The standards dictate that contractors in the latter two regions are allowed to install 13-SEER heat pumps and air conditioners until mid-2016 (or until supplies run out); then, they must only offer 14-SEER (or higher) equipment. Many HVAC distributors in those regions stocked up on 13-SEER equipment ahead of the deadline and are happy to see that their bets paid off as the inventory flew off the shelves."

"The plant is having process issues, and the culprit appears to be a process centrifugal pump. The area production manager has asked you to check the pump to see if it is operating on its curve. “Pump won’t pump, make pump pump,” he says. Sounds like a reasonable request. However, other questions need to be answered, such as: Where is the pump running on its curve? If it is not running on its curve, why?"
