Recently, most of the northern region of high temperature to attack, more than 35 degrees high temperature lasted four or five days, shopping malls, office areas and other large public places to open the air conditioning, the “air conditioning” is not as simple as we think, this is an HVAC system. HVAC is an integral part of the project building, including: heating, ventilation, air-conditioning system in these three areas, the normal operation of the HVAC system, without the help of pressure sensors. In the HVAC automated control system, the end pressure sensor and intelligent controller is the key equipment to ensure the stable operation of all operating systems and achieve environmental protection and energy saving. In the indoor vent of the central air conditioner, the pressure sensor is used to detect the air pressure difference between the two ends of the filter mesh at the vent. The screen is used to filter the dust suspended in the ventilation duct. Over time, more and more dust accumulates on the filter screen, gradually affecting the air flow through the screen. As a result of poor air circulation, the air pressure difference between the two ends of the screen increases. The pressure sensor senses the pressure change, the host computer receives the signal from the pressure sensor, when the pressure sensor signal value reaches the alarm point, it will start to alarm, prompting cleaning staff to replace or clean the filter. In addition to monitoring the concentration of dust in the filter, the pressure sensor is also used to control the volume of air supplied by the air supply outlet. The pressure sensor is a competent prosecutor. Pressure sensors guarantee the safe operation of the whole HVAC system.
