What is the role of the differential pressure sensor
Driven by the dual-carbon policy, modern building automation and HVAC technologies intelligently match energy production, energy distribution, air conditioning, and heat recovery to ensure that energy is used in a resource- and cost-efficient manner. Differential pressure sensors can be used to measure small differential pressures in air conditioning technology and building automation, helping to increase the energy efficiency of heating, ventilation and air conditioning systems.
In order to ensure the air circulation of large shopping malls, underground places and intelligent buildings, variable air volume control must be carried out. Too much air will waste electric energy, and too little air will affect people's breathing comfort. The air volume entering the air outlet of the variable air volume box is measured by a differential pressure sensor, and the area temperature is measured by connecting a temperature sensor. Based on the temperature set point, the air volume required by the area is obtained through an algorithm, and compared with the measured air volume, the air valve actuator of the variable air volume box is adjusted through the digital signal output, so that the air valve is in a controlled position and the area can be maintained. The temperature is at the set value and at the same time meets the minimum air volume requirements of the area.
Controlling the air volume by monitoring the air pressure with a differential pressure sensor is an effective solution that can reduce the owner's primary investment and operating costs.
At the same time, air filters are a critical component of HVAC, and over time they can accumulate dust, reducing airflow. Monitor the pressure on both sides of the filter through the differential pressure sensor, judge the airflow change, and remind the cleaning personnel to replace or clean the filter in time, otherwise it will consume more power to restore the airflow to the required level, and it will also give other systems in the system Components bring additional wear and tear.
