The air ejected from rooms and heat production points, such as kitchen escape hoods (18), fumes of the heat production generators (15), is intaken and let into the economizer which regenerates its enthalpic contents. From the picking up net (2), the filtered air is first passed into a rotating recuperator and then on the evaporator of a heat pump transfering its enthalpic contents to the renewal air. This air thus preheated gets integrating thermal energy in the condenser of the heat pump and, under circumstances, also through an electrical battery. n The said air is conveyed by means of the delivery net (10) to the premises; at their entrance, it can be subsequently heated in an independent way by a hot water battery. |
