Energy efficiency ... meeting higher standards and lowering operating costs Who's helping you meet the challenge? Behind the trends and spikes, global demand is driving the price of energy upward. The price would be higher still if it weren't for efficiency improvements over the last thirty years. Since 1970, research shows that energy intensity (the amount of energy it takes to produce one dollar's worth of goods) in the U.S. industrial sector fell by about 50 percent. Half of this reduction is due to improved energy efficiency. And there’s more good news: significant opportunities remain to further reduce energy consumption overall. For example, consider that a typical supermarket uses between three and six million kWh of electric power each year. With more than 31,000 supermarkets in North America, total energy consumption could be as high as 186 billion kWh. In commercial buildings, a 1999 survey shows 1.08 trillion kWh were consumed. On this scale, even small improvements in equipment efficiency will have a big impact. |

See new savings with a combined focus To help improve energy efficiency in OEM equipment and systems, Danfoss provides advanced component and control technologies. For example, Danfoss ADAP-KOOL® control systems have helped one global retailer with 10,000 stores worldwide save over 270,000 kWh per year. On the component side, our Danfoss TXV thermostatic expansion valves maintain a constant evaporator superheat to keep the evaporator active throughout its entire length, maximizing its efficiency and reducing compressor run time in every application. Currently, Danfoss TR6 thermostatic expansion valves are helping the manufacturers of residential air-conditioning systems meet the SEER 13 energy requirements mandated by the Department of Energy. |
