Abstract:
An HVAC system includes an evaporator coil and a metering device fluidly coupled to the evaporator coil. The HVAC system also includes a variable-speed circulation fan and a condenser coil fluidly coupled to the metering device. The HVAC system also includes a variable-speed compressor fluidly coupled to the condenser coil and the evaporator coil and a controller operatively coupled to the variable-speed compressor and the variable-speed circulation fan. The controller is configured to measure a speed of the variable-speed compressor, calculate a normal cooling Cubic Feet per Minute (CFM), measure a speed of the variable-speed circulation fan, and determine if the speed of the variable-speed circulation fan exceeds the normal cooling CFM. If the speed of the variable-speed circulation fan exceeds the normal cooling CFM, the HVAC controller adjusts a speed of at least one of the variable-speed compressor and the variable-speed circulation fan.
