The Dual Work Exchanger EnergyRecovery DWEER is an energyrecovery device. In the 1990s developed by DWEER Bermuda and licensed by Calder AG ref http www.hwsdesalination.com Membrane 20Desalination.html Membrane Desalination ref for use in the Caribbean . Seawater reverse osmosis SWRO needs high pressure and some of the reject stream can be reused by using this device. According to Calder AG, 97 of the energy in the reject stream is recovered. The DWEER system uses a piston doublechamber reciprocating hydraulically driven pump, and a patented valve system in a high pressure batch process with large pressure vessels, similar to a locomotive , to capture and transfer the energy lost in the membrane reject stream. Its advantage is its high efficiency rate, but it suffers from complex and large mechanical components which are susceptible to corrosion from seawater due to its metal composition. ref http www.sciencedirect.com science? ob ArticleURL& udi B6TFX 44BNGN9 11& user 10& rdoc 1& fmt & orig search& sort d&view c& version 1& urlVersion 0& userid 10&md5 58b2e9a6896ada95cd4b671e63d40d64Energy A twelve year history of large scale application of work exchanger energyrecovery technology ref References reflist energy stub Category Water power ... more details

In architecture , an airshaft is a small, vertical space within a tall building which permits ventilation of the building s interior spaces to the outside. The floorplan of a building with an airshaft is often described as a square donut shape. Alternatively, an airshaft may be formed between two adjacent buildings. Windows on the interior side of the donut allow air from the building to be exhausted into the shaft, and, depending on the height and width of the shaft, may also allow extra sunlight inside.

Unreferenced date July 2008 Otheruses Ventilation In firefighting , ventilation refers to the tactic of creating a draft with an opening above or opposite the entry point so that heat and smoke will be released, permitting the firefighters to find and attack the fire. If a large fire is not properly ventilated, not only will it be much harder to fight, but it could also build up enough poorly burned smoke to create a smoke explosion , or enough heat to create a flashover . Contrarily, poorly placed or timed ventilation may increase the fire s air supply, causing it to grow and spread rapidly. Mechanical fans can be used for such ventilation tactics, as can existing openings such as window s, skylight window skylights or heat smoke vents on the roof. If there is no suitable existing hole, firefighters may use their equipment to make one, such as specialised saw s for cutting a large hole in the roof. A conical hose stream aimed around an opening of a window or door, etc. entrains smoke and thus increases the exhaust rate of smoke from the space. This is a process called hydraulic ventilation . This strategy might be used when the fire is small and protecting property from smoke damage can be achieved safely. It can also be used more aggressively when a structure is fully involved and the smoke is obstructing the nozzlemans view of the hotspots. High rise buildings sometimes also incorporate fans to produce a positive pressure in stairwells and elevator shafts to reduce smoke infiltration into those spaces. When glass windows in a burning structure burst from internal pressure and heat, or the fire burns through the roof, it may be said to have auto ventilated or self ventilated.

The source of these gases are equipment that runs on diesel engine s, blasting with explosives , ref name Hard Rock Miner s Handbook Section 18 cite book last De la Vergne first Jack title Hard Rock Miner s Handbook publisher McIntosh Engineering date 2003 location Tempe, Arizona Tempe North Bay, Ontario North Bay ... isbn 0 968006 1 6 ref and the orebody itself. ref MNCU1107A Implement the Ventilation Management Plan Commonwealth of Australia 2001 ref The largest component of the operating cost for mine ventilation is electricity to power the ventilation fans, which may account for one third of a typical underground mine s entire electrical power cost. ref name Hard Rock Miner s Handbook Section 18 Types of ventilation Flow through ventilation is the main ventilation circuit for the mine. Air enters the mine from surface via a shaft mining shaft , raise mining ventilation raise or adit . The air is distributed through the mine via internal ventilation raises and ramps, and flows are controlled by regulators and permanently mounted ventilation fans.

High frequency ventilation is a type of mechanical ventilation that employs very high respiratory rate s 60 breaths per minute and very small tidal volume s usually below anatomical dead space . ref name krishan cite journal author Krishnan JA, Brower RG title High frequency ventilation for acute lung injury and ARDS journal Chest volume 118 issue 3 pages 795 807 year 2000 pmid 10988205 doi 10.1378 chest.118.3.795 http www.chestjournal.org cgi content full 118 3 795 Free Full Text . ref High frequency ventilation is thought to reduce ventilator associated lung injury VALI , especially in the context of ARDS and acute lung injury . ref name krishan This is commonly referred to as lung protective ventilation . Fact date March 2008 Types of High Frequency Ventilation There are different flavors of High frequency ventilation . ref name krishan Each type has its own unique advantages and disadvantages. The types of HFV are characterized by the delivery system and the type of exhalation phase. High Frequency Ventilation may be used alone, or in combination with conventional mechanical ventilation. In general, those devices that need conventional mechanical ventilation do not produce the same ... will vary depending on the device manufacturer.

Pressure Support PS is a spontaneous mode of ventilation also named Pressure Support Ventilation PSV . The patient initiates the breath and the ventilator delivers support with the preset pressure value. With support from the ventilator, the patient also regulates the respiratory rate and the Lung volumes tidal volume . In Pressure Support, the set inspiratory pressure Support technical analysis support level is kept constant and there is a decelerating flow. The patient triggers all breaths. If there is a change in the mechanical properties of the lung thorax and patient effort, the delivered tidal volume will be affected. The user must then regulate the pressure support level to obtain desired ventilation.
