SAN DIEGO – Valves are one of those things you don’t think about – until someone tells you it’s a $300 billion market. That’s right, those things that open and close. The automotive world spends $2 billion alone on little valves inside hydraulic transmissions. Washing machines, Butterfly Valves soda dispensers, ice machines and air conditioners all require various types and sizes of valves to do their thing. The vast majority of these industrial must-haves are mechanical. Austin, Texas-based startup Microstaq wants to bring valves into the electronic age, using microelectromechanical systems (MEMS) technology. Launching here at the DEMO startup conference in San Diego, Microstaq showed off a Tic-Tac-sized – though flatter- valve made out of a sandwich of silicon. Plug Valves When an electric current is applied to the silicon it heats up and expands, shifting a tiny lever that ultimately shoves open a larger hole in the chip. That’s a valve, folks - hole that opens and closes on demand. The advantage of an electronic valve is the precision with which it can be opened and closed. In Microstaq’s case, their valve technology is initially built into a valve that will be used in an air conditioner. Air conditioners are typically been very inefficient machines. With an electronic valve installed, and electronic control system guiding it, Microstaq officials claim they can improve the overall efficiency of AC systems by 20% to 30%. Since the Filter valve can precisely control the flow of the cooling fluid, the machine can fully utilize the heat exchange, which means the compressor runs less and the overall energy use goes down. That should grab the attention of utility companies under pressure to cut greenhouse gas emissions, particularly those in the Sunbelt where air conditioning accounts for much of the electricity demand. Whether Microstaq’s claims hold up, will be known soon. The company is in field tests with two major HVAC manufacturers and expects its product to be in the market in the first half of 2009. The technology behind Microstaq’s valve was originally developed for automotive use within TRW Automotive and spun out into a standalone company in 2000. Mark Luckevich, Microstaq’s VP of engineering is quick to point out his company’s technology can’t address the entire valve market. “I would say we could apply our MEMS approach to about one-quarter to one-third of it,” he says with a smile. Of course he’s smiling – that’s still a $100 billion market to go after.

译文：电子阀承诺大型能源节约
圣迭戈 - 阀门是这些东西你不想想1 - 直到有人告诉你，这是一个三千点零零零亿美元市场。没错，那些东西，打开和关闭。在汽车世界里花费很少阀液压传动二十〇万点〇〇〇万美元单。洗衣机，苏打水饮水机，制冰机，空调，都需要不同类型和规模的阀门做他们的事。绝大多数这些工业必备的机械。得克萨斯州奥斯汀的启动麦克罗要带入电子时代的阀门，利用微机电系统（MEMS）技术。开展了在圣地亚哥演示启动大会上，麦克罗展示了井字规模 - 尽管平坦阀由一个硅三明治了。当电流应用到硅它加热和扩大，移动一个微小的杠杆，最终猛推芯片中打开一个更大的洞。这是一个阀门，人们 - 孔打开和关闭的需求。一个电子阀的优点是与它可以打开和关闭的精度。在麦克罗的情况下，他们阀技术最初是建成将在空调器用阀。空调通常是非常低效率的机器。与电子安装阀门，电子控制系统的指导它，麦克罗官员声称，他们可以提高20％，空调系统的整体效率为30％。由于阀门可以精确控制冷却液流动，机器可充分利用热交换，这意味着少压缩机运行的整体能源使用停机。这应该抓住压力下减少温室气体排放的公用事业公司的注意，特别是在阳光地带在那些对电力的需求很大空调帐户。无论麦克罗的说法阻碍，很快就会知道。该公司在现场测试的两大暖通空调制造商，预计其产品在市场将在2009年上半年。背后的麦克罗的阀门技术最初是为美国天合汽车的汽车内使用，并纺成一家独立的公司在2000年。马克Luckevich，麦克罗工程副总裁很快就指出，其公司的技术不能满足整个阀门市场。 “我想说，我们可以运用我们的MEMS的办法大约有12时45分，它的三分之一，”他笑着说。当然，他的微笑 - 这仍然是一个1000亿美元追逐。
