A functioning HVAC system is a critical requirement for all buildings to maintain sufficient and safe indoor air quality. This system has many essential components that keep it efficiently functioning, and one of them is the sensor. Sensors maintain the system's performance and ensure the occupants' health, comfort, safety, and productivity by verifying accuracy and operation.
If a building's sensor is dysfunctional, it will affect air quality, humidity, temperature, and pressure. The effects of the pandemic focused the spotlight on air quality control and its importance for all the building inhabitants. Facility managers must ensure sensors are functioning effectively and smoothly to maintain and enhance indoor air quality and reduce viral transmission through the HVAC system.
The Advantages of Utilizing HVAC Sensors
When utilized in a building, sensors provide advantages to all inhabitants in the facility. Temperature and occupancy sensors help decrease your electricity bills and make your business highly energy-efficient by monitoring the occupancy and temperature of a space and regulating heating and air conditioning accordingly.
Because of the data taken by these sensors, your HVAC system can instantly adapt and increase or reduce the air's hotness or coolness, ensuring that your business isn't heating or cooling an area more than it needs, and your system isn't expending energy. You may also utilize the data your sensors provide to learn about the air movement and quality in a space.
Furthermore, using sensors in your building helps decrease the HVAC system's degradation by preventing the system from working harder than the building demands. Also, consider installing HVAC access doors and panels to improve efficiency and safety for your personnel, especially if you need regular maintenance.
Types of Sensors Critical to Your Building
Occupancy Sensors
This sensor enhances energy efficiency by monitoring motion and light in areas. Energy savings are possible because of its seamless connection with the Building Management System (BMS), allowing room temperature control to an empty setpoint. Occupancy sensors can monitor ambient light levels, allowing the BMS to adjust the space's powered light settings.
Typically, you can find these sensors in high-traffic or secluded locations, such as the building entrance, corridors, bathrooms, floors, office spaces, among others. Some occupancy sensors even have designs meant to be unobtrusive. Its integration with the BMS will provide energy savings by regulating the space temperatures to the unoccupied setpoint.
Pressure Sensors
Pressure sensors assess the pressure decrease from various devices and filters, efficiently notifying the system for necessary maintenance or replacement. For efficient HVAC system operation, accurate pressure reading is critical. Pressure sensors can measure high and low pressures in air and water settings, providing correct differential pressure and velocity measurements for dependable monitoring.
Clogged HVAC filter recognition, static duct pressure, Variable Air Volume (VAV) control, HVAC transmitters, and indoor air quality (IAQ) monitoring systems are just a few of the applications. A typical sensor with an auto-zero function that manually calibrates itself every ten minutes will have excellent zero-point stability and high accuracy.
Indoor Air Quality Sensors
Sensors that monitor indoor air quality (IAQ) are becoming more significant to limit the spread of harmful pathogens through the HVAC system. The restoration of buildings' HVAC systems is essential for ensuring appropriate and safe indoor air quality (IAQ). Increased airflow, better filtration, and air cleaning strategies optimize occupant safety, convenience, and efficiency.
Temperature Sensors
This sensor monitor and measure water and air temperature to adjust the HVAC's heating and cooling functions, which results to efficiency in energy consumption. This sensor's data may provide a basis for future adjustment, making your decisions more accurate as time passes. Using this sensor will lessen the burden on your HVAC system and optimize it, prolonging its intended lifespan.
Humidity Sensors
Humidity can directly affect the inhabitants of a building, and its control is vital for the facility to operate. If out-of-control mold growth occurs, it will risk the occupant's health because it thrives in a humid environment. It will also threaten the building's structural integrity, interfere with production, and cause damage to goods and even artworks.
This sensor will add clean steam to the airstream, raising the humidity of the area when needed. Use more accurate and dependable sensors which are not susceptible to drift like the capacitive technology (CMOS) sensors.
As a building owner or manager, the top priority is always the comfort, safety, and well-being of all the occupants using the facility. If you lack the necessary information, do not hesitate to consult a licensed professional. Their knowledge and expertise will help guide you into making the correct decisions.
