Complex Compounds are solid-gas sorption media with the coordinative bond (sharing one or more electrons) established between metal inorganic salt-based adsorbents and polar refrigerants, such as ammonia, sulfur dioxide, and water. Complex compounds utilize this unique bond to sorb large amounts of refrigerant in a process that is reversible and provides large temperature lifts in single-stage hardware, allowing for their application to heat pump processes under adverse conditions.This paper describes the ongoing development of a solid-vapor complex-compound prototype heat pump suitable for lunar base operation. Working conditions are 4-15°C cooling and 82-93°C heat rejection. Work to meet this objective involves thermodynamic characterization of the media selected and principally tested, complex-compound stability determination, optimization of physical parameters, such as salt packing density and heat exchangers with various construction materials, and proof-of-concept prototype development.
