2. Ventilative cooling - Wikipedia

   en.wikipedia.org/wiki/Ventilative_cooling

   [7] [8] [9] The system cooling effectiveness (natural or mechanical ventilation) depends on the air flow rate that can be established, the thermal capacity of the construction and the heat transfer of the elements. During cold periods the cooling power of outdoor air is large. The risk of draughts is also important.

3. Radiant heating and cooling - Wikipedia

   en.wikipedia.org/wiki/Radiant_heating_and_cooling

   Radiant cooling systems offer lower energy consumption than conventional cooling systems based on research conducted by the Lawrence Berkeley National Laboratory. Radiant cooling energy savings depend on the climate, but on average across the US savings are in the range of 30% compared to conventional systems.

4. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   A fan coil unit (FCU), also known as a Vertical Fan Coil Unit (VFCU), is a device consisting of a heat exchanger (coil) and a fan. FCUs are commonly used in HVAC systems of residential, commercial, and industrial buildings that use ducted split air conditioning or central plant cooling.

5. Window fan - Wikipedia

   en.wikipedia.org/wiki/Window_fan

   Window fans are designed to fit into open windows, and often have expandable side panels to cover the entire window opening. Most units have either one large fan, or two small fans mounted side by side. [1] Most window fans have two or three speeds, and some are electrically reversible so that the user can switch between intake and exhaust modes.

6. High-volume low-speed fan - Wikipedia

   en.wikipedia.org/wiki/High-volume_low-speed_fan

   The air column from a 3-foot-diameter (0.91 m) fan, therefore, has more than six times as much friction interface per volume of air moved as does the air column from a 20-foot-diameter (6.1 m) fan. [8] When the down column of air from an HVLS fan reaches the floor, the air turns in the horizontal direction away from the column in all directions.

   The SEER (Seasonal Energy Efficiency Ratio) rating of a unit is the cooling output during a typical cooling-season divided by the total electric energy input during the same period. The higher the unit's SEER rating the more energy efficient it is. smoke damper A damper or adjustable louver designed to augment the ventilation of a space during ...
