Abstract
Systems and methods are described for controlling fan-only cooling. A first phase of a first cooling cycle may be initiated in an enclosure using an air conditioning system having a compressor and a fan that passes air over an evaporator coil. The first phase may include activation of the compressor and activation of the fan. A relative humidity may be measured within the enclosure during the first phase of the first cooling cycle. Subsequent to the first phase and in response to the relative humidity being determined to be below a threshold relative humidity, a second phase of the first cooling cycle may be initiated during which the fan is activated but the compressor is not activated.
