ABSTRACT:
A ventilation unit for use with a heating or cooling system that is decentralized and does not require large conduits is disclosed. The system includes at least one fresh air intake; a fan operatively connected to the at least one fresh air intake for drawing air from outside of a space into the fresh air intake; and at least one ventilation unit located in the room. The ventilation unit includes a conduit defining an air passage having a first and second opposite ends, a diffuser operatively connected to the fresh air intake for outputting fresh air near the second opposite end of the conduit and for drawing ambient air from the room through the first opposite end. The ventilation unit also includes a heating element located downstream from the first opposite end inside the conduit. The ambient air is entrained towards the heating element which heats the ambient air, and the heated air is ventilated into the room at the second opposite end of the conduit by the action of a chimney effect and the fresh air diffuser. The system provides for adequate ventilation through the use of small conduits due to the decentralized heating of the air.
