Abstract
An air conditioning system includes a mechanical refrigeration unit having a control to vary the dehumidifying capabilities of the system. The speed of the fan provided to route air in heat transfer relationship with the evaporator of the refrigeration unit is varied to vary the flow rate of the air across the evaporator. When it is desired to increase the dehumidifying capabilities of the system, the flow rate of the air is reduced. The temperature of the evaporator is monitored to decrease the flow rate of the air thereacross as the temperature of the refrigerant flowing through the coil increases and to increase the flow rate of the air across the evaporator as the refrigerant temperature decreases, to thereby maintain the refrigerant temperature in the evaporator at a predetermined level.
