HVAC Air Control

HVAC air control maintains temperature and humidity levels in a space, reducing energy costs and saving time. In addition, it helps improve indoor air quality by controlling the introduction of pollutants into a building.

In order to control the environment, a controller needs input from sensors that compares the current condition with a set point. This information allows it to make smart decisions.

Temperature Sensors

Temperature sensors are a critical part of HVAC air control. They help verify the accuracy and operation of a system to ensure it’s running efficiently and effectively.

They also monitor indoor air quality (IAQ) to slow the spread of viruses and other contaminants in an HVAC system. They can be stand-alone devices or part of equipment installations that provide integration and automation functions.

These sensors use thermistors to measure temperature, or infrared sensing to detect heat from the interior. Some use a fan to pull air past the thermistor to get an accurate reading.

Temperature sensors are used for a variety of applications, including heating, ventilation, and air conditioning systems and process control. They come in many different forms, including Pt100, NTC and thermocouple sensor elements.

Humidity Sensors

Humidity sensors measure the amount of water vapor in the air and provide an electronic signal that indicates the moisture content. They are used in a variety of applications to ensure comfortable, safe, and efficient environments.

Sensors that are faulty or out of calibration can impact the operation and accuracy of the HVAC system. This can lead to building pressure and temperature issues, reduced occupant comfort, and decreased productivity.

Adding humidity sensing to the system increases efficiencies and prevents indoor air quality problems. This also reduces compressor energy costs because outdoor air can be used for cooling in a single-economizer HVAC system.

Using these sensors in combination with thermal and airflow sensors allows the control system to operate efficiently and save on electricity. Combined sensors also enable buildings to comply with the ASHRAE 62.1 standard.

Ventilation Sensors

A central component of HVAC air control, ventilation sensors help regulate the optimum amount of outdoor air that is supplied to a building or office. They also allow for effective recirculation and process control, reducing energy consumption and helping to maintain good indoor air quality.

In addition to temperature and humidity, ventilation sensors can detect CO2 levels. When CO2 levels are too high, they send a signal to the ventilation system to turn on and provide fresh air.

Carbon dioxide sensors are now commonly used in offices around the world to keep employees feeling alert and fresh. These sensors can be combined with a building management system and a digital control ventilation unit (DCV) to automatically adjust the ventilation in different areas.

Sensors are evolving to better meet the needs of customers for cost-effective and accurate measurements of a range of physical parameters. They offer improved durability to withstand harsh HVAC environments, digital communication capabilities, lower power sensors, wireless capabilities with a variety of communication protocol options, and smaller sensors that take up less space.

Thermostats

The thermostat is the primary control for your HVAC air system. It monitors the temperature and humidity levels inside your home and communicates with your furnace, air conditioner, and blower motor to make sure that your comfort level is optimal.

Most modern smart thermostats are programmable. They allow you to program temperatures based on the time of day or your day-to-day schedule.

Some smart thermostats also offer remote sensors that let you monitor the temperature of different areas within your home. This can help you balance the heating and cooling of your entire house for more energy efficiency.

Lastly, some modern thermostats are daylight savings time ready. These automatically adjust your temperature settings when the sun rises or sets. This can save you a lot of money on your energy bills.
