Dampers and louvers are essential components in HVAC systems that can regulate airflow and temperature. Dampers are typically used to control the flow of air through ducts, while louvers can be used for both air flow control and ventilation. These devices are designed to improve the efficiency of heating and cooling systems by maintaining a consistent temperature throughout a space, and they can also help to improve indoor air quality. Louvers can also provide weather protection and prevent the entry of rain and harsh weather conditions. Whether you are designing a new HVAC system or upgrading an existing one, dampers and louvers are essential considerations that can help you achieve the best possible performance and energy efficiency.
