What is a damper used for?

A damper is primarily used to regulate draft or the flow of air within a ventilation system. By adjusting the position of a damper, airflow can be increased or decreased, allowing for better control of heating, ventilation, and air conditioning (HVAC) systems. This regulation is crucial for maintaining comfort levels in indoor spaces by ensuring that the right amount of air is distributed as needed.

In HVAC applications, dampers often help balance the airflow between different rooms or areas, contributing to energy efficiency and system performance. Properly functioning dampers can facilitate the maintenance of desired temperature and humidity levels, ensuring that the HVAC systems operate effectively and efficiently.

The other choices, while important in their own contexts, do not accurately describe the primary purpose of a damper. For instance, storing combustible materials is not related to the function of a damper, nor does it prevent heat loss directly. While dampers can play a role in managing heat, their main function is airflow regulation, not powering heating appliances.
