Abstract
An osmotically pumped environmental control system (10) comprises a closed circuit heat pipe (12) including an osmotic pump (13) with solvent and solution reservoirs (18, 14) separated from one another by a solvent permeable membrane (20). Heat is inserted into the closed path at an evaporator (22) from high temperature sources and heat is wihdrawn from the system by first and second stage cooling modules (38, 40) to withdraw heat therefrom. A further heat input (30) from low temperature sources slightly warms the condensate for return to a solvent reservoir (18).
