The mechanical bypass uses a slotted rod that is actuated by a lever on the large dashpot plunger shaft to provide another leakage path in the dashpot. The lever is positioned so that the bypass opens at a gate position above speed no load, when the unit is normally on line. If it is necessary to operate isolated, the bypass arm is moved out of the way and the unit dashpot will function normally. The solenoid operated dashpot bypass provides a leakage path in the dashpot when the solenoid is energized. The rate of leakage is. | MECHANICAL VENTILATION WITH HEAT RECOVERY IN NEW HOMES INTERIM REPORT VENTILATION AND INDOOR AIR QUALITY TASK GROUP January 2012 NHBC Foundation Housing research in partnership with BRE Trust Zero Carbon Hub The Zero Carbon Hub was established in the summer of 2008 to support the delivery of zero carbon homes from 2016. It is a public private partnership drawing support from both Government and the Industry and reports directly to the 2016 Taskforce. The Zero Carbon Hub has developed five workstreams to provide a focus for industry engagement with key issues and challenges Energy Efficiency Energy Supply Examples and Scale Up Skills and Training Consumer Engagement NHBC Foundation The NHBC Foundation was established in 2006 by NHBC in partnership with the BRE Trust. Its purpose is to deliver high-quality research and practical guidance to help the industry meet its considerable challenges. Since its inception the NHBC Foundation s work has focused primarily on the sustainability agenda and the challenges of Government s 2016 zero carbon homes target. Research has included a review of microgeneration and renewable energy techniques and the groundbreaking research on zero carbon and what it means to homeowners and housebuilders. The Zero Carbon Hub is grateful to the NHBC Foundation for its support in the dissemination of the guidance arising from this consultation.
