2. Heating, ventilation, and air conditioning - Wikipedia

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

   Many regions experience seasonal temperature extremes, which would require large-capacity heating and cooling equipment to heat or cool buildings. For example, a conventional heat pump system used to heat a building in Montana's −57 °C (−70 °F) low temperature or cool a building in the highest temperature ever recorded in the US—57 °C ...

3. Industrial fan - Wikipedia

   en.wikipedia.org/wiki/Industrial_fan

   Industrial fan. Industrial fans and blowers are machines whose primary function is to provide and accommodate a large flow of air or gas to various parts of a building or other structures. This is achieved by rotating a number of blades, connected to a hub and shaft, and driven by a motor or turbine. The flow rates of these mechanical fans ...

4. Fan heater - Wikipedia

   en.wikipedia.org/wiki/Fan_heater

   A fan heater, also called a blow heater, is a heater that works by using a fan to pass air over a heat source (e.g. a heating element). [1] This heats up the air, which then leaves the heater, warming up the surrounding room. They can heat an enclosed space such as a room faster than a heater without a fan, [2] but like any fan, create a degree ...

5. 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. FCUs are typically connected to ductwork and a thermostat ...

6. Passive cooling - Wikipedia

   en.wikipedia.org/wiki/Passive_cooling

   Passive cooling is a building design approach that focuses on heat gain control and heat dissipation in a building in order to improve the indoor thermal comfort with low or no energy consumption. [1][2] This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building (natural ...

7. Ventilation (architecture) - Wikipedia
