2. Diffuser (thermodynamics) - Wikipedia

   en.wikipedia.org/wiki/Diffuser_(thermodynamics)

   A diffuser is "a device for reducing the velocity and increasing the static pressure of a fluid passing through a system”. [1] The fluid's static pressure rise as it passes through a duct is commonly referred to as pressure recovery. In contrast, a nozzle is used to increase the discharge velocity and lower the pressure of a fluid passing ...

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. Industrial furnace - Wikipedia

   en.wikipedia.org/wiki/Industrial_furnace

   An industrial furnace, also known as a direct heater or a direct fired heater, is a device used to provide heat for an industrial process, typically higher than 400 degrees Celsius. [1] They are used to provide heat for a process or can serve as reactor which provides heats of reaction.

5. Centrifugal fan - Wikipedia

   Figure 1: Components of a centrifugal fan An external motor belt driven inline centrifugal fan discharging inline to the exterior of a building through a duct. Unlike non-inline/non-concentric impeller casing design with a cutoff blade above, the concentrically symetric cylinder casing and impeller geometry of inline type redirects the outflow around so that it is parallel to the inflow of gases.

6. Hydronics - Wikipedia

   en.wikipedia.org/wiki/Hydronics

   Excessive heat or pressure may cause the system to fail. At least one combination over-temperature and over-pressure relief valve is always fitted to the system to allow the steam or water to vent to the atmosphere in case of the failure of some mechanism (such as the boiler temperature control) rather than allowing the catastrophic bursting of ...
