A control system for a cooling system for reducing humidity levels in a gas such as ambient air is provided. The cooling unit includes at least one of a compressor and a chiller, and cooling coils are connected to the cooling unit. A fan blows the gas onto the cooling coils. A fan speed controller is connected to the fan and variably controls the speed of the fan. A dry bulb temperature sensor is in thermal communication with the gas and connected to the controller, and a moisture sensor is in communication with the gas and connected to the controller. The speed of the fan is determined by the controller based on signals received from the dry bulb temperature sensor and the moisture sensor. By varying the speed of the fan, the moisture content of the gas can be modified much more precisely than by conventional air conditioning methods.

[ What is claimed is:] [1.]1. A cooling system for reducing humidity levels in a gas, comprising:a cooling unit, said cooling unit including at least one of a compressor and a chiller;cooling coils connected to said cooling unit;a fan blowing the gas onto said cooling coils;a fan speed controller connected to said fan, said controller variably controlling a speed of said fan;a dry bulb temperature sensor in thermal communication with the gas, electrically connected to said controller and sending first signals to said controller; anda moisture sensor in communication with the gas, electrically connected to said controller and sending second signals to said controller,wherein said speed of said fan is determined by said controller based on said first and second signals,wherein said moisture sensor comprises:a cooled mirror in thermal communication with said cooling coils, said cooling coils cooling said mirror;a heater connected to said controller and in thermal communication with said cooled mirror;a light source disposed near said mirror, said light source shining light onto said mirror;a photosensor connected to said controller and disposed near said mirror adapted to detect the light shined from said light source and reflected by said mirror, said photosensor sending said second signals to said controller,wherein if condensation forms on said mirror, said photosensor will not detect a full amount of the light shined from said light source.
