Indoor units are the visible and operational heart of any HVAC system, responsible for delivering conditioned air into interior spaces. From residential apartments to commercial buildings, the selection of the right indoor unit affects energy efficiency, indoor air quality, and overall user comfort.
In this article, we’ll explore the main types of indoor units used in modern HVAC systems and highlight Clivet’s advanced European-engineered solutions, which are available in Iran through Atrina HVAC Solutions.
Indoor Unit
