Patent ID: 8292192

Claim:
A variable stage incubator humidity control system, the system comprising: at least one incubator; a spray assembly in thermal communication with the incubator; a sensor in thermal communication with the incubator, the sensor sensing at least relative humidity and air temperature; and a controller in communication with the sensor and the spray assembly, the controller being structured to calculate an actual dew point and compare the actual dew point with a target dew point, the controller controlling the spray assembly to maintain the actual dew point in a pre-programmed range and to thereby control conditions in the incubator; wherein the controller is also structured so that the controller directs fluid to spray lines and nozzles, thereby enabling the nozzles to dispense the fluid, the number of nozzles dispensing fluid is based on an algorithm so that the number of nozzles dispensing fluid is equal to the product of: 2(2 n −1), where n is the number of spray lines.
