Heating, ventilation, and air conditioning are used to control what?

Heating, ventilation, and air conditioning (HVAC) systems are primarily designed to control the environment within an enclosure. This means that these systems help to manage multiple factors that contribute to climate control within a building, such as temperature, humidity, and air circulation, thus ensuring a comfortable and safe environment for occupants.

The control of indoor temperature is achieved through heating during cold weather and cooling during hot weather. Ventilation is crucial for bringing in fresh air, expelling stale air, and regulating humidity levels. Overall, the HVAC system works to establish a balanced indoor environment, catering to the comfort and health needs of the inhabitants.

While factors like indoor humidity, energy consumption, and air quality are also relevant and impacted by HVAC systems, they are considered aspects or effects of the broader goal of controlling the indoor environment. The HVAC system ultimately aims to provide a holistic management approach to create a conducive living or working space.
