2. Chilled beam - Wikipedia

   en.wikipedia.org/wiki/Chilled_beam

   A chilled beam is a type of radiation/convection HVAC system designed to heat and cool large buildings through the use of water. [1] This method removes most of the zone sensible local heat gains and allows the flow rate of pre-conditioned air from the air handling unit to be reduced, lowering by 60% to 80% the ducted design airflow rate and the equipment capacity requirements.

3. Underfloor air distribution - Wikipedia

   en.wikipedia.org/wiki/Underfloor_air_distribution

   Air returns from the room at ceiling level or the maximum allowable height above the occupied zone. [1] The UFAD system takes advantage of the thermal plume and stratification phenomenon: the conditioned air is supplied directly to the occupied zone (OZ). The thermal plumes generated by the occupants and other heat sources introduce the ...

4. Displacement ventilation - Wikipedia

   en.wikipedia.org/wiki/Displacement_ventilation

   Pairing displacement ventilation with radiant chilled ceilings is an effort to mitigate this problem. [12] According to some studies, displacement ventilation systems can only provide acceptable comfort if the corresponding cooling load is less than about 13 Btu/h-sf or 40 W/m 2 .

5. Radiant heating and cooling - Wikipedia

   en.wikipedia.org/wiki/Radiant_heating_and_cooling

   Since radiant heating systems tend to be in the floor, the obvious choice would be to use the same circulation system for cooled water. While this makes sense in some cases, delivering cooling from the ceiling has several advantages. First, it is easier to leave ceilings exposed to a room than floors, increasing the effectiveness of thermal mass.

6. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   Due to their simplicity, flexibility, and easy maintenance, fan coil units can be more economical to install than ducted 100% fresh air systems (VAV) or central heating systems with air handling units or chilled beams. FCUs come in various configurations, including horizontal (ceiling-mounted) and vertical (floor-mounted), and can be used in a ...

7. Thermal destratification - Wikipedia

   en.wikipedia.org/wiki/Thermal_destratification

   The study also showed that energy waste due to stratification was present at ceiling heights ranging from 20 ft. to 40 ft, and higher ceilings caused higher energy waste, even at the same ΔT. Since ΔT tends to be higher in taller ceilings, the effect of stratification is compounded, causing substantial energy waste in high-ceiling buildings.

   Rooms and suites come with floor-to-ceiling windows, marble fixtures, large bathrooms, and seating areas, while restaurant and bar options range from a 24-hour bar to steakhouses, barbecue ...

9. Fan filter unit - Wikipedia

   en.wikipedia.org/wiki/Fan_filter_unit

   Filter ceiling grid of a cleanroom for microelectronic (semiconductor) manufacturing with filter fan units installed A fan filter unit ( FFU ) is a type of motorized air filtering equipment. It is used to supply purified air to cleanrooms , laboratories , medical facilities or microenvironments by removing harmful airborne particles from ...
