2. Register (air and heating) - Wikipedia

   en.wikipedia.org/wiki/Register_(air_and_heating)

   Usually, a register is placed near a window or door, which is where the greatest heat/cooling loss occurs. [4] [5] In contrast, returns (grilled ducts which suck air back into the HVAC system for heating or cooling) are usually placed in the wall or ceiling nearest the center of the building. Generally, in rooms where it is critical to maintain ...

3. Heating, ventilation, and air conditioning - Wikipedia

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

   The heat can be transferred to the surrounding air using radiators, hot water coils (hydro-air), or other heat exchangers. The radiators may be mounted on walls or installed within the floor to produce floor heat. The use of water as the heat transfer medium is known as hydronics. The heated water can also supply an auxiliary heat exchanger to ...

   The Emerson "Heat Fan", the first ceiling fan to use a stack motor A close-up of the dropped flywheel on a FASCO "Charleston" ceiling fan Stack-motor ceiling fans. In the late 1970s, due to rising energy costs prompted by the energy crisis , Emerson adapted their "K63" motor, commonly used in household appliances and industrial machinery, to be ...

5. 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.

6. Air handler - Wikipedia

   en.wikipedia.org/wiki/Air_handler

   The heat pipe uses multiple sealed pipes mounted in a coil configuration with fins to increase heat transfer. Heat is absorbed on one side of the pipe, by evaporation of the refrigerant, and released at the other side, by condensation of the refrigerant. Condensed refrigerant flows by gravity to the first side of the pipe to repeat the process.

7. 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 ...
