Innengeräte

Innengeräte, a German term translating to "indoor units," refers to the components of an air conditioning or climate control system that are located within a building's interior. These units are responsible for the direct conditioning of the air in a specific room or zone. They typically house the fan that circulates air and the heat exchanger where the refrigerant absorbs heat from the room (in cooling mode) or releases heat into the room (in heating mode).

Common types of innengeräte include wall-mounted units, often seen in residential settings, which are mounted high on a wall. Ceiling cassette units are another popular option, designed to be integrated into suspended ceilings, offering a discreet and even distribution of air. Floor-standing units are also available and are typically placed on the floor, often near a window. Ducted systems utilize concealed innengeräte, usually located in attics or crawl spaces, with air distributed through a network of ducts to multiple rooms.

The primary function of an innengerät is to transfer thermal energy between the indoor air and the refrigerant circulating within the system. This process allows for the cooling or heating of the interior space. They also typically include filters to remove dust and other airborne particles, contributing to improved indoor air quality. The fan within the innengerät ensures the continuous circulation and distribution of conditioned air throughout the designated area. Control of the innengerät is usually managed by a remote control or a thermostat.
