Abstract: A method for cooling air to a predetermined outflow temperature for use in an atmosphere having a controlled humidity. In the method, a stream of air having an unknown temperature and an unknown humidity content is supplied. The air is cooled to provide cooled air having a temperature at or below the predetermined outflow temperature. The cooled air is heated when necessary to provide outgoing air having a temperature approximately equal to the predetermined outflow temperature.

Abstract: Thermal electric liquid cooling system having a tank for containing the liquid. A cooling plate is secured to the tank and forms a part of the tank. The cooling plate is formed of a heat conductive material and has first and second surfaces with the first surface in contact with the liquid in the tank. A plurality of thermal electric modules are in contact with the second surface of the cooling plate. A cooling manifold is secured to the cooling plate and is in engagement with the thermal electric cooling devices and serves to sandwich the thermal electric cooling modules between the cooling plate and the cooling manifold. Means is provided for supplying a liquid coolant to the cooling manifold to withdraw heat from the cooling manifold.
