CPC H05K 7/20145 (2013.01) [F24F 7/00 (2013.01); F28D 20/02 (2013.01); H05K 7/20127 (2013.01); F24F 2007/004 (2013.01); F28D 2020/0008 (2013.01)] | 13 Claims |
1. A ventilation and air conditioning system for a room, the room containing a heat source, the ventilation and air conditioning system comprising:
a cooled air supply;
a ventilation duct, the ventilation duct comprising a primary inlet being connected to the cooled air supply and an outlet leading into the room; and
a number of heat storage elements arranged inside the ventilation duct between the primary inlet and the outlet, such that during operation of the cooled air supply there is a forced stream of cooled air through the ventilation duct, thereby cooling and preferably freezing the heat storage elements,
a secondary inlet into the ventilation duct, the secondary inlet being in flow communication with the room and which during operation of the cooled air supply is closed by a damper,
the damper being designed to automatically open in a passive manner when the forced stream of cooled air from the cooled air supply stops, such that a natural convection airflow through the ventilation duct is supported, the natural convection airflow being cooled by transferring heat to the heat storage elements.
