Liquid ventilator can perform therapeutic lung lavage, the washout of endogenous and exogenous debris from the lungs, without suspension of ventilation support (without apnea). For example, literature data suggest a radical change in the treatment of meconium aspiration syndrome (MAS) by considering the use of a liquid ventilator.
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
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 ...
A device that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This cooled liquid flows through pipes in a building and passes through coils in air handlers, fan-coil units, or other systems, cooling and usually dehumidifying the air in the building. Chillers are of two types; air-cooled or water-cooled.
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.
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.
ASHRAE Standard 62.2 was adopted in 2004; it clarifies the ventilation air requirements for low-rise residences. The Standard specifies that forced ventilation is required in houses with infiltration less than 0.35 ACH. [2] This is typically accomplished with heat recovery ventilation or exhaust fans running constantly or periodically.
