Abstract
The microprocessor-based control system selects the appropriate indoor airflow (fan speed) to place the system in an optimal efficiency range. The indoor fan speed is further controlled based on humidity measurements, to produce a slower airflow when conditions are humid. This helps remove a greater amount of moisture from the air. Occupant comfort is enhanced by microprocessor control of the indoor fan speed to stay within the boundaries of the cooling mode comfort envelope.
