2015 AHR Expo in Chicago on Record Pace
WESTPORT, Conn.—Early indications are that the 2015 AHR Expo in Chicago is on track to set size records. "To accommodate the demand for exhibit space in Chicago, we’ve already had to expand the space layout," said Clay Stevens, president of International Exposition Company, which produces and manages the AHR Expo. "Chicago is historically the site of our largest events, and it is very encouraging that so many HVAC&R manufacturers and suppliers have already reserved space." Stevens cited generally positive news about the economy and increased demand in the building sector as factors leading to optimism about the Show. The 2015 AHR Expo will be held January 26–28. AHR Expo is cosponsored by ASHRAE and the Air-Conditioning, Heating and Refrigeration Institute (AHRI).

Does Daylight Saving Time Actually Save Energy?
MEDFORD, Mass.—The reason we "spring forward" each year for daylight saving time (DST) has more to do with what we spend on summer fun than with lowering our consumption of energy, according to an article from Tufts University. The article cites research contrary to a study by the U.S. Department of Energy (DOE). Some studies report small reductions in electricity use, but the most comprehensive study of household energy demand and many others report an increase in overall energy consumption ranging from 1% to 4% during DST, says Michael Downing, a Tufts lecturer in English and author of Spring Forward: The Annual Madness of Daylight Saving Time. “The barbeque grill and charcoal industries say they gain $200 million in sales with an extra month of daylight saving—and they were among the biggest lobbies in favor of extending DST from six to seven months in 1986,” he said. He also cited the gasoline and retail industries as other benefactors of increased activity, and energy use, during DST. He added that the reduced cost of indoor lighting on sunny spring and summer days is offset by higher air-conditioning costs at offices, factories and shopping malls.

HARDI, DOE Reach Settlement in Regional Efficiency Standards Lawsuit
COLUMBUS, Ohio—Heating, Air-Conditioning and Refrigeration Distributors International (HARDI) announced this week that a settlement has been reached in the long-running lawsuit regarding regional efficiency standards for residential gas furnaces and central air conditioners finalized by the U.S. Department of Energy (DOE) in 2011. Under the settlement agreement, the regional nonweatherized furnace standards will be vacated, and DOE will undertake another rulemaking for those products. In addition, the agreement provides for an 18-month grace period—until July 1, 2016—for compliance with the regional air-conditioning standards, a provision designed to avoid stranded inventory. In addition, DOE has agreed to engage in a process to review the regulatory processes that established the regional efficiency standards. Shortly after announcement of the settlement, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) announced its approval of the resolution of the lawsuit. AHRI and Air Conditioning Contractors of America (ACCA) were signatories to the settlement agreement.

European Parliament Formally Adopts HFC Phase-Down Regulations

BRUSSELS—The European Parliament this week formally passed legislation calling for a 79% reduction in hydrofluorocarbons (HFCs) used in refrigeration and air conditioning. The "F-Gas" regulation will cap the amount of HFCs that can be placed on the market in the European Union (EU) and will gradually reduce it to 21% of current levels by 2030. The regulations go into effect Jan. 1, 2015. In its "plenary session"—the meeting of the entire Parliament, which culminates the work of committees—the body passed the F-Gas regulations as proposed by 644 votes to 19 (with 16 abstentions). The proposal was made last December (an article was linked to in the Jan. 2 issue of The HVAC&R Industry). The European Parliament is the directly elected parliamentary institution of the 28-nation EU, and acts as its legislative branch.

Indiana Could Turn Lights Out on State Energy Efficiency Program
INDIANAPOLIS—A two-year-old program designed to cut energy consumption in Indiana homes, schools, stores and factories could end Dec. 31, under a bill that passed the Senate by a wide margin March 10. Senate Bill 340 would shut down the Energizing Indiana program, under which energy auditors visit homes and businesses and recommend ways to reduce energy consumption. The bill, which also passed the House two weeks ago, now goes to Gov. Mike Pence for his consideration. Its future is not certain. "The governor recognizes the important role energy efficiency has to play in Indiana’s energy portfolio," said Kara Brooks, the governor’s spokeswoman. "SB 340 proposes a departure from Indiana’s current program, and the governor is carefully weighing whether this is best for Indiana."

Engineers Remain Confident in Future of Employers, Jobs
ATLANTA—Engineers largely feel secure in their jobs and are confident in their employers' futures, according to the latest Randstad Engineering Employee Confidence Index. Each quarter, Randstad Engineering places a numerical value on its index based on an online survey. The most recent poll found a strong level of confidence in workers' outlook, with 72% showing confidence in their companies' future. Eighty-six percent of respondents also reported feeling secure in their positions. However, there was a one percentage point decrease from the previous index of engineers who feel confident in their ability to find a new job. Still, 60% of engineers feel confident they can get a new job should they lose their current position.

Weather Satellite Attempting to Clean 'Space Junk'
TANEGASHIMA, Japan—Scientists hope that the recent launch from Japan of the H-2A rocket will be a giant leap toward cleaning up tons of "space junk" orbiting the Earth. The rocket, which was developed by the U.S. and Japan, includes two satellites. One satellite will monitor global weather, and the other, called the Space Tethered Autonomous Robotic Satellite-2 (Stars-2), is designed to harness space debris to make orbital lanes safe for future equipment and explorers. It features a tether, measuring 300 m (1,000 ft) when fully extended, which will generate electricity along its length as it passes through Earth’s magnetic field. The electricity will reduce the speed of pieces of dead rockets and satellites that have ended their missions and lure them closer to Earth, where they should burn up upon reentry into the atmosphere. The second satellite will have a more mundane, yet important, task of monitoring global rainfall and forecasting extreme weather. NASA estimates that there are more than 20,000 pieces of junk floating in space that are at least the size of a softball.

Electronic Expansion Valves Versus Thermal Expansion Valves
By Renato Lazzarin, Daniele Nardotto, and Marco Noro, Ph.D.
Many refrigerating machines use thermostatic expansion valves (TEVs). However, TEVs have some characteristics that can limit versatility and performance of the machines. For example, they require a minimum pressure drop between condensation and evaporation. Some applications, such as refrigerating machinery in supermarkets, are particularly sensitive to the problems of TEVs. One solution to the problems of TEV is the electronic expansion valve (EEV), which controls the refrigerant flow at the evaporator by means of a pressure sensor and a temperature sensor. This article evaluates the possibilities of using EEV versus TEV.

Economizer From Enervex
ALPHARETTA, Ga.—Enervex introduces the VHX 10-300 Vortex Heat Exchanger, a high-efficiency economizer with a built-in bypass. It uses a radiator-style heat exchanger, which helps it to be much smaller than traditional economizers. The design creates a turbulent flow across the heat exchanger surface, maximizing heat transfer. When combined with a mechanical draft fan, a single VHX can serve multiple boilers, no matter whether they are of atmospheric, fan-assisted or forced-draft design.
