types of dampers in hvac

Like dampers, louvers are usually made of aluminum or steel. 1. There are motorized dampers, backdraft dampers, pressure relief dampers and make-up air.Each has its benefits and no matter what your needs are there is one that is perfect for your situation. Type of HVAC systems can be divided into central HVAC systems and local HVAC systems. Fire dampers are crucial passive fire protection products and are used in air conditioning, ventilation and heating systems. Louvers may be adjustable, or suitable for applications that require noise control. In case of fire, the fire and gas dampers will close automatically, preventing additional oxygen to enter the space to fuel and spread a fire. Manual Dampers. To correctly control the spread of smoke through the HVAC system, the specifier should create a design using Fire Dampers and Smoke Control Dampers in the correct location. What type of control action will the damper perform? There are many different types of dampers that can be used to regulate the air distribution in your home. control actuators, Siemens is a recognized global leader in HVAC damper actuators. Where your HVAC system penetrates fire and smoke barriers, dampers are installed to sustain the integrity of the barrier ratings. Types of Dampers in HVAC. For example, in a house, the main floor may be served by one heating zone while the upstairs bedrooms are served by another. Parallel blade dampers are con-structed so all the blades move in the same direction and in parallel. Choose from both rectangle and round configurations designed specifically for things like safety applications, low-leakage and heavy duty industrial needs, and backdraft for pressure relief. A heating and air conditioning system is designed to produce hot and cold air and force it into a building structure, such as a home or commercial facility. It is another type of VCD that differs somewhat from the previous VCD shown above. These are parallel and opposed blade dampers. Dampers fall into five types, each with a specific function. If a damper does not close properly, the integrity of the fire barrier is compromised. 1.) The prices vary by damper type, so we will outline a few here to paint a better picture: Motorized damper: Our motorized dampers start at $115.01 for a 4 inch 24 volt damper with no end switch. Kele offers the following types of commercial volume control dampers: Different types of Dampers and Louvers. At Johnson Controls, we offer Damper Controls in a diverse range of models. They can also be used to redirect conditioned air out of closed-off rooms, which prevents wasted … Opposed blade dampers have the blades moving in opposing directions. The High-temperature damper operates continuously at 300°c for up to 2 hours. Parallel blade damper are constructed so that all the blades are moved … In HVAC installations two different types of rectangular dampers are used to modulate air flow. Fire Dampers (journal,2006) . Another type of damper is viscoelastic dampers that stretch an elastomer in combination with metal parts. Volume air dampers control overall air flow as part of the building's heating and cooling system. A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system. There are two common types of HVAC dampers: manual and automatic. These devices are also used in air mixing zones to get hot and cold air. With the increased use of dynamic fire control systems, it was discovered that ordinary static type fire dampers would not always close if the HVAC system blower continued to run. Having this ability allows people to control the amount of air that enters their home or business. Zone dampers are generally driven electrically as used in home HVAC systems. This article defines and describes barometric dampers, draft regulators, automatic flue dampers, draft inducers, zone dampers, HVAC supply register controls, fire dampers, automatic fire and smoke dampers, fireplace dampers, and fresh air inlet dampers and controls.
