2. Heat recovery ventilation - Wikipedia

   en.wikipedia.org/wiki/Heat_recovery_ventilation

   Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

3. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   A unit ventilator is a fan coil unit that is used mainly in classrooms, hotels, apartments and condominium applications. A unit ventilator can be a wall mounted or ceiling hung cabinet, and is designed to use a fan to blow outside air across a coil, thus conditioning and ventilating the space which it is serving.

4. Heating, ventilation, and air conditioning - Wikipedia

   en.wikipedia.org/wiki/Heating,_ventilation,_and...

   Electrical heaters are often used as backup or supplemental heat for heat pump systems. The heat pump gained popularity in the 1950s in Japan and the United States. [14] Heat pumps can extract heat from various sources, such as environmental air, exhaust air from a building, or from the ground. Heat pumps transfer heat from outside the ...

5. Overhead clothes airer - Wikipedia

   en.wikipedia.org/wiki/Overhead_Clothes_Airer

   Cords go from the metal tether points to pulleys mounted on the ceiling, and then to a cleat hook mounted on the wall. The defining feature of this airer is its pulley system. The airer is lowered to be loaded or unloaded, then raised to move the items up into warmer air and as out of the way of room occupants as the ceiling height allows.

7. Thermal destratification - Wikipedia

   en.wikipedia.org/wiki/Thermal_destratification

   Axial destratification fans are self-contained units that are installed in an array at the ceiling with the goal of blowing conditioned air in the ceiling down to the floor, where people live and work. Because axial fans are designed to blow air straight down at the floor, they can be used in ceiling and roof structures over 100 ft. tall.

8. Kitchen ventilation - Wikipedia

   en.wikipedia.org/wiki/Kitchen_ventilation

   Kitchen ventilation is the branch of ventilation specialising in the treatment of air from kitchens. [1] It addresses the problems of grease, smoke and odours not found in most other ventilation systems. Restaurant kitchens often use large extractor hoods. Kitchen ventilation equipment includes an extractor hood or canopy, and a filtering ...

9. Radiant heating and cooling - Wikipedia

   en.wikipedia.org/wiki/Radiant_heating_and_cooling

   Radiant systems, encompassing both heating and cooling, transfer heat or coolness directly through surfaces, such as floors, ceilings, or walls, instead of relying on forced-air systems. These systems are broadly categorized into three types: [19] thermally activated building systems (TABS), [20] embedded surface systems, and radiant ceiling ...
