  2. Liquid ventilator - Wikipedia

    en.wikipedia.org/wiki/Liquid_ventilator

    A liquid ventilator is similar to a medical ventilator except that it should be able to ensure reliable total liquid ventilation with a breatheable liquid (a perfluorocarbon). [ 1 ] [ 2 ] Liquid ventilators are prototypes that may have been used for animal experimentations but experts recommend continued development of a liquid ventilator ...

  3. Windcatcher - Wikipedia

    en.wikipedia.org/wiki/Windcatcher

    The construction of a windcatcher depends on the direction of airflow at that specific location: if the wind tends to blow from only one side, it is built with only one downwind opening. This is the style most commonly seen in Meybod , 50 kilometers from Yazd: the windcatchers are short and have a single opening.

  4. Ventilation (architecture) - Wikipedia

    en.wikipedia.org/wiki/Ventilation_(architecture)

    For residential buildings, which mostly rely on infiltration for meeting their ventilation needs, a common ventilation rate measure is the air change rate (or air changes per hour): the hourly ventilation rate divided by the volume of the space (I or ACH; units of 1/h). During the winter, ACH may range from 0.50 to 0.41 in a tightly air-sealed ...

    Where possible, sufficient detail is supplied in the bibliographic details for users to trace and order the material via their own libraries. Topics covered by AIRBASE include ventilation strategies, design and retrofit methods, calculation techniques, standards and regulations, measurement methods, and indoor air quality and energy implications.

  7. Building airtightness - Wikipedia

    en.wikipedia.org/wiki/Building_airtightness

    An airtight building has several positive impacts [3] when combined with an appropriate ventilation system (whether natural, mechanical, or hybrid): [4] Lower heating bills due to less heat loss, with potentially smaller requirements for heating and cooling equipment capacities; Better performing ventilation system

  8. Engineering controls - Wikipedia

    en.wikipedia.org/wiki/Engineering_controls

    Local exhaust ventilation (LEV) is the application of an exhaust system at or near the source of contamination. If properly designed, it will be much more efficient at removing contaminants than dilution ventilation, requiring lower exhaust volumes, less make-up air, and, in many cases, lower costs.

  9. Mechanical systems drawing - Wikipedia

    en.wikipedia.org/wiki/Mechanical_systems_drawing

    These drawings are often a set of detailed drawings used for construction projects; it is a requirement for all HVAC work. They are based on the floor and reflected ceiling plans of the architect. After the mechanical drawings are complete, they become part of the construction drawings, which is then used to apply for a building permit.
