What engineers need to know about smoke and fire dampers
AMCA’s collection of technical tips and guidance for commissioning and periodic performance testing Active dynamic fire protection includes the design of all systems to extinguish or extinguish the fire. This process is done in parallel with the evacuation of residents. This process includes smoke detectors, building pressure design, fire alarms, sprinklers, emergency exit signs, and […]
The Importance of Using Smoke Dampers in Fire Extinguishing Systems | | The importance of using smoke dampers in the design of fire extinguishing systems
According to NFPA[1] surveys in the 1930s, the National Fire Insurance Organization suggested that dampers should be used in the HVAC system to prevent the passage of smoke, flames, and heat caused by fire. Since then, a large number of experts in fire science, efficiency and effectiveness of automatic closing of smoke and fire dampers […]
Air damper and specifications of all types of dampers
What is a damper? A damper is a valve or metal plate that blocks or adjusts the flow of air inside a duct, chimney, BOX VAV, air conditioner or other air control (adjustment) equipment. A damper can be used to shut off the central air conditioning system (heating or cooling) in a room that is […]
VAV terminal control methods
VAV terminal control methods In order to control the temperature of a space, it is necessary to somehow compensate for the changes in the heating and cooling load. The amount of heating and cooling loads in a building varies and is affected by several factors. These factors include weather changes, seasonality, time of day and […]
Effective factors in choosing building ventilation system
Designers have various options to choose from when designing building air conditioning systems, and choosing one of these systems is not an easy task. The opinions of the project owners for the selection and installation of equipment, as well as the operating costs of the system should be taken into account during the design. The […]
