HVAC Contractors Prepare for DOE Efficiency Mandates

Air Conditioning/Heating/Refrigeration News, Oct. 18, 2015, by Joanna R. Turpin.

"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."

Cool Irrigation Thermal Storage

Engineered Systems, Oct. 2015, by Phil Jankovich, Stephen Connor, and Matt Wilson.

"...the design team realized they could pump irrigation water from the campus' main distribution line at night to use for cooling during the day if they could figure out how to store thousands of gallons of water on the new building's first floor.... Piping strategy, CFD, and chilled beams fill out an innovative closing argument on behalf of this Utah law school."

Efficiency In The Round [VAV systems ductwork]

Engineered Systems, Oct. 2015, by Eugene Smithart.

"When it comes to ductwork for VAV systems, could the shortest path to better air handling cost and efficiencies be round (or spiral)? Aided by static regain and streamlined installation, here's the case for no more corners."

Energy Star Honors 2015’s Most Efficient Geothermal Units

Air Conditioning, Heating & Refrigeration News, Sep. 28, 2015, by Herb Woerpel.

"Every year, the U.S. Environmental Protection Agency’s (EPA’s) Energy Star program acknowledges products it deems “Most Efficient” in the marketplace. This effort identifies leading products among those that qualify for Energy Star designation in numerous product categories. Here is a snapshot of Energy Star’s Most Efficient Geothermal Heat Pumps of 2015."

Ford in Europe Factories Save Enough Energy to Power Oxford for a Year

Automotive World, Oct. 15, 2015.

"Ford in Europe is on course to achieve a reduction in energy usage of 25 per cent from 2011 to 2016 per vehicle produced, following investments of €23 million specifically targeting energy waste."

Proper Procedure for a Boiler-Room Assessment

HPAC Engineering, Sep. 2015, by Steve Connor and Randy Smith.

"Efficiency, sustainability, reliability, safety—these are the keys to the optimal performance of a facility, and they are the focus of a properly conducted boiler-room assessment. This article discusses what goes into a properly conducted boiler-room assessment."

Chiller Retrofit: Cooler In Columbia [SC]

Engineered Systems, Sep. 2015, by Dan Reider.

"This chiller plant retrofit team encountered challenging existing conditions and answered with savvy choices for piping and valves as well as the chillers. Good communication, accurate documentation, and a creative bidding idea you might want to borrow also contributed to bringing the mechanical work in effectively and on budget."

Replacing The "Engine" On Your Boiler System

Engineered Systems, Sep. 2015, by Ray Wohlfarth.

"Pumps, flues, valves, sizing, maintenance... there's a lot more to consider than just the boiler. Keep the car metaphor in mind, and your next replacement might not drive you to despair."

Supermarkets: A Bellwether of Industry Changes

Air Conditioning, Heating & Refrigeration News, Sep. 7, 2015, by Ron Rajecki.

"Supermarkets and their needs will always be one of the front-and-center elements of the HVACR industry. These high-profile businesses operate long hours, use large amounts of energy, and have tens of thousands of dollars in perishable product that needs refrigeration 24/7. Trends in supermarkets can often provide insights into changes to come for the rest of the commercial refrigeration world, and — as is the case industry-wide — refrigerants are on the minds of many in the supermarket sector."

Direct-Fired Technology: From Makeup Air to Space Heating

ASHRAE Journal, Sep. 2015, by Thomas Boeckermann, and others.

"Direct-fired heating technology is a safe, energy-efficient, and cost-effective means to provide heating for a wide range of applications. The two main uses—makeup air and space heating—have different applications and require different approaches to deliver the most efficient design. This article summarizes the basic operating principles, safety, energy performance, psychrometric behavior, and recommendations for the use of direct-fired heating units."
