AMCA Publication 502 - Damper Application Manual for Heating, Ventilating, and Air Conditioning is a guide to understanding the various types of dampers available and items to be considered for their proper use. Dampers classified as fire dampers, heat dampers, and smoke dampers are not included.
Building automation (BAS), also known as building management system (BMS) or building energy management system (BEMS), is the automatic centralized control of a building's HVAC (heating, ventilation and air conditioning), electrical, lighting, shading, access control, security systems, and other interrelated systems.
Every control system must guarantee first the stability of the closed-loop behavior. For linear systems, this can be obtained by directly placing the poles. Nonlinear control systems use specific theories (normally based on Aleksandr Lyapunov's Theory) to ensure stability without regard to the inner dynamics of the system. The possibility to ...
Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the input electricity.
A regular, professional hygiene check of a vehicle's air conditioning system includes checking the drain lines for the condensation water, annual cleaning of the air conditioning system evaporator and changing the interior air filter (pollen filter). In particular, the unhindered drainage of the condensation water from the air conditioning ...
A sound attenuator, or duct silencer, sound trap, or muffler, is a noise control acoustical treatment of Heating Ventilating and Air-Conditioning (HVAC) ductwork designed to reduce transmission of noise through the ductwork, either from equipment into occupied spaces in a building, or between occupied spaces.

Blast Damper with integral grill to shield against flying objects. A blast damper is used to protect occupants and equipment of a structure against overpressures resultant of an explosion. The blast dampers normally protect air inlets and exhaust penetrations in an otherwise hardened structure.
The application of trickle vents in naturally-ventilated spaces can help contribute to IEQ Credit 2 under the LEED green building rating system. LEED EA Credit 2 references CIBSE Applications Manual 10, which provides advice on the design of naturally-ventilated spaces, recommending the installation of trickle vents in naturally-ventilated spaces.
