What’s The Difference Between Valve And Damper Actuators?

In HVAC systems, two major components play several roles. The Valve and actuator dampers are essential components of the system, but with different functionalities. These two components are responsible for the smooth functioning of the entire system. The actuators are responsible for the control of dampers. Also, the damper actuators make use of low voltage signals in the heating system. There are many more differences between the valves and the actuators, and you will learn about them in this article.

The functions of the actuators in the damper

Among the role of the actuators is the placement of the dampers. The actuator is responsible for placing the damper between the open and closed-end of the system. You have an opportunity to make your entire HVAC system function effectively with good actuators. On the other hand, the valve is responsible for regulating the fluids, including the liquid and gasses.

The actuators ensure the proper functioning of the HVAC damper

The functions of the actuators are focused on the damper. For the damper to function properly, the actuator should be in good working condition. It is a critical component of the HVAC system. The damper will not be able to function effectively without the help of the actuator. That is one of the differences existing between the actuator damper and the valve.

The functions of the valves that made it different from HVAC

The valve has various functions in the HVAC system. It is responsible for pressure processing and flow regulation. So, you have an opportunity to benefit more from the HVAC system when the valve is in good working condition. Some of the functions of the valve you need to know include:

  • Starting and stopping the flow
  • Reducing and increasing a flow
  • Controlling 
  • and reducing the flow of fluid
  • Relieving a pipe system for some kind of pressure.

The characteristic of a valve that made it different from actuator damper

The flow of fluid through the valve is varied to alter the pressure. While the valve is responsible for the HVAC system performance, the actuator is responsible for the damper system. So, if you want the damper to function effectively, you should install an actuator. Also, if you want your HVAC system for effective functioning, you need a good valve.

Conclusion

Go on take advantage of the two most essential elements of the HVAC system, and you will be happy in the end. You will realize the best way to benefit more from your heating system when both actuator damper and valves.

Making Heating and A/C More Efficient: Pressure Sensors

Positive air pressure happens when the inside pressure is greater than the outside pressure. This keeps the outside air out. That’s why you feel a rush of cold air when you open the doors of a building. Positive air pressure is beneficial as it prevents high humidity which is the main causes for mold, mildew and property damage although it’s not always applicable in all situations. You need the pressure sensors to detect and control the positive pressure.

Points to note about Negative air pressure

Negative air pressure on the other hand occurs when the outside pressure is greater than the inside pressure allowing air to enter the building. This creates a vacuum that sucks in air containing harmful dust particles and allergens which can be harmful to occupants in the building. In this situation, high levels of humidity can leak into a building causing discomfort as well. A good example of negative air pressure is a door that is difficult to pull open whereas positive air pressure does the opposite.

Why you need the pressure sensors

As the name suggests, pressure sensors simply measure the air pressure within a building or room. Pressure sensors are used in several components such as compressors, coolers and heat recovery systems. They are used in keeping track of pressure levels in case any issues may arise. This is useful in having an ideal heating, cooling and ventilation. Pressure is a very important aspect of any HVAC system. Air pressure is the pressure within a container due to the compression of atmospheric gases. In any building, there are two types of air pressure circulating namely:

  • Positive air pressure
  • Negative air pressure

Reasons to avoid negative air pressure

As much as negative air pressure may seem like a cause for discomfort, it also has its applications in small spaces such as kitchens as it helps keep smoke from leaking out to other parts of the building. It can also be used in hospitals to contain dangerous viruses, pathogens and contaminants for research, quarantine and treatment.

When to go for the pressure sensors

As we had said earlier, pressure sensors measure air pressure. They do so by measuring the electric charge and displaying the results. HVAC systems are designed primarily for air ventilation and a pressure sensor is just one of many components used to make these systems more efficiently. Pressure systems measure the air flow and pressure throughout the system for proper air distribution. Measuring the air pressure can help the HVAC system optimize the temperature of the building and reduce energy costs.

Why The Air Return Is So Important For Proper HVAC System

The most obvious use of the air return vent is bringing back air to the HVAC system. It is a necessary component for balancing air flow in the system and ensuring that there is enough air to repeat the process of reconditioning and filtering. The HVAC system works by heating or cooling air (depending on the temperature) and pumping it back into the home. Return air vents serve this purpose by pulling in the air and pushing it back into the system. Return vents also have filters that prevent harmful particles, allergens and debris from infiltrating the air in your home. Sometimes more than one return vents may be needed if your HVAC system can’t keep up with your desired temperature.

The need for HVAC system in the house

Just as you breathe in and out as a person, your home or workplace also have this exchange of airflow. Air conditioners work by absorbing warm air and moisture from your home, cools it and then sends it back into your home through the return air vents.  Return air vents have their benefits mainly:

  • Saves energy cost
  • Maintaining air quality
  • Maintaining air flow

How to maintain the HVAC for proper functionality

Without air return vents, the HVAC system collapses. Damaged or blocked vents can obstruct proper airflow and cause inefficiency in the system. However, having proper air return vents can improve airflow and save money spent on energy bills. These vents should be properly cleaned, sealed and connected to prevent harmful particles from contaminating the airflow. These particles are capable of causing medical issues such as respiratory illnesses and allergies.

Also, return air vents are very easy to maintain. The reason is because the only problem it has is the collection of dust overtime. The filter which collects the dust can be easily cleaned with a wet rag on a daily basis. Neglecting the dust can lead to moisture growth on the return vent.

The truth about the HVAS system you should know

Although it’s not advisable to clean parts of your HVAC system, you can always clean your return vents. It’s also a good idea to change the filter as it gets dirty and blocked over time. If there are any damages to your HVAC system or return vent, you should hire a professional technician to fix the problem. You should never block your return vents with furniture or other objects. Doing so can hinder the airflow of your home and it will put a great deal of stress on your AC unit. Ultimately, this will lead to serious damages that cost money to fix.
