Abstract:
1. A method of controlling a thermal diffusion chamber by steps comprising: monitoring an exterior temperature of a sealed process chamber; transmitting an exterior thermal measurement value to a control system based on the monitored external temperature of the sealed process chamber; comparing the external thermal measurement value to a predetermined value; generating a control signal based on the comparison of the external thermal measurement value to the predetermined value; providing the control signal to a fluid handling system, wherein the fluid handling system modulates flow of a first fluid around the exterior of the sealed process chamber based on the control signal; providing the control signal to a closed loop heat exchange system, wherein the closed loop heat exchange system modulates flow of a second fluid within an interior cavity of the sealed process chamber based on the control signal; and providing the control signal to an open loop heat exchange system, wherein the open loop heat exchange system modulates flow of a third fluid within the interior of cavity of the sealed process chamber.
