The Function Of Damper Actuators In HVAC Systems

The HVAC or Heating, Ventilation, and Air Conditioning system is one of the most essential systems found in a particular building, home, and other commercial facilities like restaurants, malls, and offices. Its part has become one of the essentials like the electrical system, plumbing, structure, and water system.

The function of HVAC

The primary function of HVAC is to provide better air circulation in the area while controlling the temperature. The goal of HVAC is to avoid recirculation of air by providing fresh air from the outside while cleaning the air inside.

The damper and the HVAC

One crucial part of HVAC is damper. The damper controls the air coming from the outside. It becomes fully opened or fully closed, depending on the setting and temperature from the outside. The damper has one crucial part, and that is the actuator. What are the functions of damper actuators in the HVAC System? Let’s find out.

It’s a control device

For the dampers to function, they have to be controlled by actuators. Actuators, as it goes by the name, are those that put the damper into action. They allow the damper to move by closing or opening it, controlling the airflow that comes from the outside. Actuators are electronically controlled. It can either be automatic or controlled by a person. There are also pneumatic dampers which are controlled by airflow.

It’s a protective device

Actuators can act as protection when the need arises. During the extremely cold conditions, the actuators can close the dampers to prevent cold air from coming. This will help heat up the entire facility by controlling the cold air that comes in a while, producing warm temperatures inside.

It can also protect the building during the fire as well as those who are inside the building from the smoke. The damper can be fully closed to prevent fire or smoke from entering the rooms and prevent further damage and injuries. The control of air circulation plays a significant role in any situation. That is the job of actuators.

Since actuators are playing an essential function in the HVAC system, it is crucial to get a high-quality product. High-quality products will surely function well, especially that most actuators right now are automatic. It’s quite convenient and efficient to have actuators working automatically, quickly responding to any condition necessary. It’s a system worth investing in to create a pleasant and conducive environment for both residential and commercial.

Do Air Handling Units All Use The Same Type Of Control Valves?

Air handling units or AHU are part of the HVAC or heating, ventilating, and air-conditioning system. AHU controls the circulation of air in the HVAC system. Maybe you have seen it already. It’s a huge metal box that has all the complete components that control air circulation. Components such as chambers, heating or cooling elements, blowers, dampers and filter racks are found here.

Since the primary function of AHU is to control air circulation, it has valves for control. So the question is, do all AHU has the same type of control valves? Let’s learn more about this.

There are different types of AHUs

Air handling units have lots of variations and designs over the years. Some components and features have changed or modified to perform better. They come in different sizes also, and most of them are on the rooftop or placed outdoor to allow fresh outdoor air to come in. This would help prevent recirculating the air.

Because of the fact that there are various AHUs, there are multiple valves as well. That would also depend on the structure and type of set up you have in a building or commercial facility. The set up would depend on the size and number of rooms inside the building or facility.

It differs on how the valve should function

The control valve is part of the heating and cooling system of the HVAC. It controls the flow of liquid that cools or heats down the coil pad where the air passes through. As the thermostat sensors identify the temperature of a room or a unit, it will send signals to the heating and cooling coils where the air passes through. The coil will then be replaced by a hot or cold flow of liquid inside. Therefore the air that passes through it will become cold as it enters the ventilation shaft and goes down towards the room.

There are a two-way valve and a three-way valve. This valve helps control the flow of liquid towards the coil to make heating or cooling faster. They also play an important role in maintaining the temperature in a particular room. Each of these types of valves has different kinds that are used today. That would depend on how you want your valves to function. The valves used will depend on the amount of air-conditioning you want in your facility. This will also include the number of floors, rooms, and other areas that require ventilation.
