Abstract
An HVAC system includes a face-split evaporator. The face-split evaporator includes a top evaporator circuit positioned above a bottom evaporator circuit. The system includes a first compressor associated with the top evaporator circuit, a second compressor associated with the bottom evaporator circuit, and a controller communicatively coupled to the first and second compressors. The controller receives a demand request, which includes a command to reduce power consumption by the HVAC system by a predefined percentage. In response to receiving the demand request, the second compressor is turned off thereby decreasing power consumption by at least the predefined percentage. A portion of a liquid condensate formed on a surface of the top evaporator circuit is allowed to fall on a surface of the bottom evaporator circuit such that a portion of a flow of air passing across the bottom evaporator is evaporatively cooled by the portion of the liquid condensate.
