ABSTRACT:
An integrated air conditioning and water heating system provides cooling of a comfort zone, as required, as well as water heating. A variable speed compressor delivers compressed refrigerant first to a water heat exchanger and then to an outdoor condenser coil. From there the refrigerant cycles through an indoor evaporator coil back to the compressor. When the demand for water heating is above a predetermined amount and the cooling load is below a predetermined cooling load threshold, a full condensing mode is selected in which most of the heat from the comfort zone is used for water heating. If the cooling demand is high or if the water heating demand is low, a desuperheating mode is selected in which most of the heat is transferred to the outdoor air. The outdoor coil temperature is monitored and if it is above a safe limit, the desuperheating mode is selected. In the full condensing mode the outdoor fan is held off. In the desuperheating mode, the outdoor fan is energized.
