Which type of system is used for temperature control in buildings?

The HVAC system, which stands for Heating, Ventilation, and Air Conditioning, is the correct choice for temperature control in buildings. This system is specifically designed to regulate indoor climate, ensuring comfortable temperatures throughout various seasons. It functions by drawing in air, conditioning it (either heating or cooling), and then distributing that air through the building to maintain the desired temperature.

The HVAC system integrates various components—such as furnaces or heat pumps for heating, air conditioners for cooling, and ventilation systems to improve air quality—making it essential for overall climate control in both residential and commercial settings. This comprehensive approach to managing air temperature and flow distinguishes HVAC systems from other options.

While electrical systems can support HVAC systems by powering them, they are not responsible for temperature control themselves. Hydraulic systems, which utilize liquid to transfer energy, and pneumatic systems, which use compressed air, are also not primarily designed for temperature regulation in buildings, making them less relevant in this context.
