<p>The air conditioning system for a room operates on the principle of a heat pump and uses two heat exchangers (5, 7), one outside the room (1) and one inside. The position of the heat exchangers can be reversed, depending whether heating or cooling is required. Thus, one heat exchanger (5) may be incorporated inside a cooling unit (4) inside the room and the other heat exchanger (7) is inside a heating unit (6) outside the room. The two units are interconnected by a line (8) with plug-in connections at each end. This line may be a flat section cable with two holes through it circulating the heat exchange medium, and also has the power supply wires for the units embedded in it.</p> |
