Residential ventilation

Fresh air with dehumidification

DHRN units are designed for for use in residential and commercial environments where the cooling is made by ceiling / wall / floor radiant systems.

Combines high efficiency heat recovery capacity to dehumidification treatment of the airflow to be supplied to the room, generally mixing of fresh air coming from outdoor and recirculated air coming from indoor cleanest rooms.

That’s possible thanks to pretreatment , whose heat transfer fluid is the water coming from radiant system that pass trough a finned coil, and a later phase whose the transfer fluid is the refirgerant gas that flows in a standard refrigeration circuit by compressor (the last one activated only on summer mode).

The treated air, accordingly, is supplied with a marked dehumidifying capacity related to room condition, providing drying of wet places.
On winter mode (compressor off), in addition to heat recovery capacity, the air to be supplied is also further heated by finned coil, supplied by water plant of radiant system.
