Abstract

La présente invention concerne un condensateur et se rapporte au domaine de la climatisation et de la réfrigération. Ce condensateur, qui permet d'évacuer l'air intérieur, comprend un boîtier et des tuyaux de condensation logés dans ce boîtier. Une entrée d'air pour l'introduction d'air intérieur à basse température et une sortie d'air pour l'évacuation de l'air soumis à un échange thermique avec les tuyaux de condensation sont disposées dans le boîtier. Un ventilateur est disposé sur un côté de l'entrée et/ou de la sortie d'air. En cours d'utilisation, le condensateur, qui permet d'évacuer l'air intérieur dans la présente invention, est inséré directement dans une paroi. Le présent condensateur peut amener l'air intérieur à basse température introduit dans le condensateur à subir un échange thermique avec les tuyaux de condensation. Cela permet d'abaisser la température ambiante par condensation et d'améliorer l'effet de condensation. Le présent condensateur peut être utilisé pour ventiler de l'air par évacuation de l'air intérieur vers l'extérieur par l'intermédiaire de la sortie d'air disposée sur le boîtier.
