There are two primary NASA applications for the SEAR technology. (1) Nonventing thermal control systems for space suits. A SEAR-based thermal control system rejects heat by radiation instead of venting water vapor. The advanced LCAR design we demonstrate in this program can provide a multifunctional structure and double as the shell that houses the portable life support system; and (2) Nonventing thermal control and thermal storage system for manned spacecraft. A SEAR-based thermal control system can be attractive for lunar orbiters and other spacecraft that will operate in highly variable thermal environments. A SEAR can provide high-efficiency thermal energy storage and heat rejection that vents no water. Both SEAR applications are based on the same LCAR module technology that we will demonstrate in Phase II.
Technology developed under this program can be used for commercial dehumidification systems, particularly heat-driven systems in which desiccant/enthalpy wheels are used to transfer water vapor between air streams. The lithium-chloride containment and management technology developed for the SEAR can be applied to make these systems more compact and efficient. SEAR technology can also benefit microclimate cooling systems for industrial, medical, military, and recreational purposes. Absorption cooling can enable lightweight, low-power, man-portable refrigeration systems that can remove both heat and humidity from fully enclosed protective garments.
