  • Airconditioning system suitable for residential use
    Patent number: 4207754
    Abstract: An airconditioning system includes a heat exchanger having high and low temperature heat exchange chambers in which a fluid is cooled or heated, respectively. An air circuit is associated with each chamber. A register having four orifices and a valve is associated with each air circuit, and the system can easily be switched from a heating to a cooling mode, or vice versa, by actuation of the valves to cause the air entering the environment to be conditioned to flow through a selected one of the two air circuits.
