A system for controlling the temperature and relative humidity of the interior chamber of a respirator is disclosed. In the preferred embodiment, the system includes a body configured to conform to the face of a user and form an interior chamber defined by the respirator body and the face of the user. The system includes a sight region in the upper portion of the body through which the user can see. A thermoelectric module having a first temperature plate and a second temperature plate is interposed in the lower portion of the body so that the first temperature plate contacts the interior chamber and the second temperature plate contacts the external environment. A power source provides DC current to the thermoelectric module causing a temperature differential between the first temperature plate and the second temperature plate. Preferably, the plates of the thermoelectric module include heat exchangers and fans for maximizing the efficiency of the thermoelectric module. The power source includes means for reversing polarity to reverse the temperature differential of the thermoelectric module and means for modulating current to the thermoelectric module to control the temperature differential.

1. A system for controlling the temperature within a respirator comprising:a body having a horizontal axis defining an upper and lower portion thereof, the body configured to generally conform to the face of a user and having a sight region configured to allow the user to see through the body, the body adapted to define an interior chamber at the face of the user for isolating a portion of the user's face from an exterior environment; a thermoelectric module located in the lower portion of the body, the module having a first temperature member and a second temperature member, the thermoelectric module being coupled with the body so that at least one surface of the first temperature member is located within the interior chamber and at least one surface of the second temperature member is located in the exterior environment; and a power unit for supplying power to the thermoelectric module.
