Understanding Differential Pressure for Facilities Management

Differential pressure is a term that is used in facilities management to refer to the difference in pressure between two points. This difference in pressure can have a significant effect on the operation of a facility and its ability to remain energy efficient. In this blog, we will explore the concept of differential pressure and how it is used in facilities management.

What is Differential Pressure?

Differential pressure is the difference between two points in pressure. It is measured in millibars (mbar) and is calculated by subtracting the lower pressure value from the higher pressure value. Differential pressure can be used in a variety of ways, such as to measure the difference in air pressure between two points in a building or to measure the pressure in a pipe or duct. It is a powerful tool that can be used to calculate the efficiency of a facility.

How is Differential Pressure Used in Facilities Management?

Differential pressure is often used in facilities management to help measure the overall efficiency of a building or facility. The differential pressure between two points can be used to measure the air flow rate in a building, as well as the air leakage. This can help facilities managers identify any issues with air flow or air leakage which can then be addressed and corrected.

Differential pressure can also be used to measure the efficiency of heating and cooling systems in a facility. By measuring the differential pressure between two points, it is possible to calculate the total amount of energy that is being used to heat or cool a building. This information can then be used to make changes to the system to make it more energy efficient.

Conclusion

Differential pressure is a key concept in facilities management that can be used to measure the efficiency of a building or facility. By measuring the difference in pressure between two points, it is possible to calculate the air flow rate, air leakage, and the efficiency of heating and cooling systems. By using this information, facilities managers can make changes to increase the efficiency of their facility and reduce energy costs.
