Abstract: The present invention discloses a system and method for supercritical water gasification (SCWG) of biomass materials wherein the system includes a SCWG reactor and a plurality of heat exchangers located within a shared pressurized vessel, which decouples the function of containing high pressure from the high temperature function. The present invention allows the heat transfer function to be conducted independently from the pressure transfer function such that the system equipment can be designed and fabricated in manner that would support commercial scaled-up SCWG operations. By using heat exchangers coupled to the reactor in a series configuration, significant efficiencies are achieved by the present invention SCWG system over prior known SCWG systems.

Abstract: A hybrid air conditioning system for cooling a chamber, the hybrid system including a desiccant-coated heat pump configured to cool, through evaporation and condensation of a refrigerant, a first air stream OA, and an indirect evaporative cooling, IEC, unit configured to cool a second air stream MA, which is related to the first air stream OA, through direct heat exchange between wet channels that are placed adjacent to dry channels. The desiccant-coated heat pump is fluidly connected to the IEC unit so that a generated supply air stream SA is dehumidified by a desiccant material coated on first and second heat exchangers of the desiccant-coated heat pump.
