Effective temperature controller and method of effective temperature control

摘要

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.
