  • Method and apparatus for control of cooling system air quality and energy consumption
    Patent number: 8651391
    Abstract: An energy saving air quality control system modulates supply fan speed by use of controlled, variable-frequency drive controls for automatic dampers or suction pressure to maintain adequate air flow across the evaporator coil at partial cooling loads. Indexing the fan speed to maintain the suction pressure of the energized coil controls the maximum relative humidity of the conditioned space. Demand ventilation in the system balances air quality and energy consumption by controlling the outdoor air damper in response to indoor CO2 and humidity levels.
