INTEGRATED HEATING AND FRESH AIR SUPPLY DEVICE FOR USE WITH AN AIR DISTRIBUTION SYSTEM

摘要

A ventilation unit (30), which does not require large air conduits (16) is combined with a decentralized heating or cooling system (37). The system includes at least one fresh air intake (16); a fan (21) operatively connected to the at least one fresh air intake for drawing air from outside of a space into the fresh air intake (16); and at least one ventilation unit (30) located in the room (3). The ventilation unit (30) includes a conduit (31) defining an air passage having first (32) and second (33) opposite ends, a diffuser (35) operatively connected to the fresh air intake (16) for outputting fresh air near the second opposite end (33) of the conduit (31) and for drawing ambient air from the room through the first opposite end (32). The ventilation unit (30) also includes a heating element (37) located downstream from the first opposite end (32) inside the conduit (31). The ambient air is entrained towards the heating element (37) which heats the ambient air, and the heated air is ventilated into the room at the second opposite end (33) of the conduit (31) by the action of a chimney effect and the fresh air diffuser (35). The system provides for adequate ventilation due to the use of small air conduits (16) and the decentralized heating of the air.
