A heat exchanger (3) exchanges energy with the ambient air, and is supplied with cold medium through a cooling circuit (2) from a primary source (5) or through a heating circuit (1) from a secondary heat source (6). A regulator (19) connects the source with its corresp. circuit and heat exchanger, and in a second position disconnects that source from the circuit. In this second position of the first regulator, a second regulator (16) permits energy transmission connection of the second source to the corresp. circuit via a second heat exchanger (15). |
