ventilation
The process of replacing stale or warm air in a room with fresh air from outside. This can happen by opening windows or through technical systems.
Eine regelmäßige Lüftung des Zimmers ist wichtig für ein gesundes Raumklima.
Regular ventilation of the room is important for a healthy indoor climate.
ventilation system
The technical system or device that provides air exchange in a building. A synonym for ventilation unit.
Im fensterlosen Bad ist die Lüftung kaputt, deshalb riecht es muffig.
The ventilation system in the windowless bathroom is broken, so it smells musty.
The noun 'die Lüftung' (ventilation) is derived directly from the verb 'lüften' (to air out, to ventilate). The ending '-ung' turns the activity (lüften) into a noun that can describe both the process and the result or device.
Bitte lüfte dein Zimmer, bevor du zur Schule gehst.
Please air out your room before you go to school.
You can tell whether the process (m01) or the system (m02) is meant from the verb. Verbs like 'sorgen für' (to provide for) or adjectives like 'regelmäßig' (regular) point to the process. Verbs like 'einschalten' (to switch on), 'ausschalten' (to switch off), or adjectives like 'kaputt' (broken) and 'laut' (loud) refer to the system.
Wir müssen für eine bessere Lüftung im Konferenzraum sorgen.
We need to provide better ventilation in the conference room.
When referring to the process of airing out or ventilating, typical expressions are 'für Lüftung sorgen' (to provide ventilation), 'regelmäßige Lüftung' (regular ventilation), or specific methods such as 'Stoßlüftung' (brief, intensive ventilation).
Im Winter ist die Stoßlüftung energieeffizienter als ein gekipptes Fenster.
In winter, brief intensive ventilation is more energy-efficient than a tilted window.
When 'Lüftung' (ventilation) refers to the technical system, it is often combined with verbs like 'einbauen' (to install), 'warten' (to service), 'reinigen' (to clean), or 'einschalten' (to switch on). It can also 'laut sein' (be loud) or 'ausfallen' (fail, break down).
Ein Techniker kommt heute, um die Lüftung zu warten.
A technician is coming today to service the ventilation system.
air conditioner
Both can contribute to a more pleasant indoor climate, but they do not have exactly the same purpose. Ventilation replaces stale air with outdoor air, while an air conditioner mainly regulates temperature and humidity and can also recirculate air. Use „Lüftung“ for exchanging air and „Klimaanlage“ for regulating the indoor climate.
Wir öffneten das Fenster, damit die Lüftung frische Luft ins Büro brachte.
We opened the window so that the ventilation could bring fresh air into the office.
Wir schalteten die Klimaanlage ein, weil es im Büro zu warm und zu feucht war.
We turned on the air conditioner because the office was too warm and humid.
