Application of Differential Pressure Sensor in HVAC System

As building maintenance needs continue to increase, HVAC systems are no longer adequate for stand-alone use. Whether it is a commercial, retail or industrial building, differential pressure sensors play an important role in monitoring the safety and comfort of the building. When combined with pressure technology, HVAC systems can operate at optimal levels and also improve building maintenance. There are three ways to realize it.


1. The maintenance of the differential pressure sensor's detection area


Quality control of the building is fundamental. Differential pressure sensors can closely monitor pressure changes and point out whether there is a dilemma. Pressure drops in the room or through the filter can alert service technicians for maintenance.


Differential pressure sensors monitoring differential pressure in HVAC systems are especially important for critical applications such as the detection of stairwell pressurization, clogged filters or clean rooms.


Differential pressure sensors can be used in: compressors, chillers, boilers, heat recovery systems, burner controls, VAV.


2. Improve indoor air quality with differential pressure sensors


The sensor improves the efficiency of the air conditioning system by measuring air flow and pressure, which is an effective air distribution system. However, buildings require a certain amount of air flow depending on the function of the building and the average number of occupants.


For example, a shopping center with a lot of traffic and people emitting CO2, a differential pressure sensor can ensure that a large amount of airflow is pumped back into the building so that people can breathe easily. Differential pressure sensors are especially beneficial for cleanrooms by assessing and monitoring air pressure, quality and ventilation. All important considerations are needed in cleanroom environments.


Differential pressure sensors can be used for: VAV (variable air volume) control, static air duct pressure, air handling systems.


3. Optimize systems with differential pressure sensors


By measuring the pressure and airflow in individual rooms, owners can optimize heating, cooling and air flow. By improving the efficiency of HVAC systems, sensors can reduce building energy consumption and costs.


Maintenance of the detection area can also reduce energy costs and prevent unnecessary energy loads from faulty equipment. Differential pressure sensors can also ensure compliance with legally required standards.
