What is the primary function of an electric motor in an HVAC system?

The primary function of an electric motor in an HVAC system is to convert electrical energy into mechanical energy for operation. This mechanical energy is essential because it powers various components within the HVAC system, such as fans, compressors, and pumps. These components work to circulate air, compress refrigerants, and perform other critical tasks necessary for heating, cooling, and ventilating indoor spaces.

By transforming electrical energy into mechanical motion, the electric motor enables the HVAC system to function effectively. This mechanical output is what allows for the movement of air and the operation of other essential parts, ensuring that the system can meet the desired temperature and air quality standards within a building.

While the other options touch on aspects of energy and functionality, they do not accurately describe the primary role of an electric motor in HVAC systems. For instance, converting electrical energy into thermal energy relates more to heating elements rather than the motor itself, and storing energy pertains to battery systems, not electric motors. Similarly, measuring temperature and humidity is a function of sensors, not the motor, which focuses on energy conversion for mechanical work.
