   en.wikipedia.org/wiki/Kitchen_hood

   Ducted hoods blow the gases to the outdoors; ductless hoods filter the air, often using activated charcoal, to remove odor and smoke particles from the air and then release the cleaned air back into the kitchen. A ducted system removes of all forms of airborne contamination, while a ductless one recirculates heat and moisture.

3. Fan coil unit - Wikipedia

   en.wikipedia.org/wiki/Fan_coil_unit

   These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.

4. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   However, if a building does need full heating, combustion central heating may offer a more environmentally friendly solution than electric resistance heating. This applies when electricity originates from a fossil fuel power station , with up to 60% of the energy in the fuel lost (unless utilized for district heating ) and about 6% in ...

5. Radiator (engine cooling) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(engine_cooling)

   A system of valves or baffles, or both, is usually incorporated to simultaneously operate a small radiator inside the vehicle. This small radiator, and the associated blower fan, is called the heater core, and serves to warm the cabin interior. Like the radiator, the heater core acts by removing heat from the engine.

6. Ducted fan - Wikipedia

   en.wikipedia.org/wiki/Ducted_fan

   The most common ducted fan arrangement used in full-sized aircraft is a turbofan engine, where the power to turn the fan is provided by a gas turbine. High bypass ratio turbofan engines are used on nearly all civilian airliners , while military fighters usually make use of the better high-speed performance of a low bypass ratio turbofan with a ...
