A system and method for transferring heat from a process source and dissipating it to the ambient atmosphere. The system uses a low-volatility, hygroscopic working fluid to reject thermal energy directly to ambient air. Direct-contact heat exchange allows for the creation of large interfacial surface areas for effective heat transfer. Heat transfer is further enhanced by water vapor pressure gradients present between the equilibrium moisture content of the working fluid and the ambient air. Cyclic absorption and evaporation of atmospheric moisture dampens variations in cooling capacity because of ambient temperature changes. The low-volatility and hygroscopic nature of the working fluid prevents complete evaporation of the fluid and a net consumption of water.

The method can be used in the field of gas hydrate geology for determining the pore water content in equilibrium with gas hydrate in different dispersed media, including rock, sedimentary deposits and soil systems. A dispersed-medium specimen which has been pre-dried and weighed is placed between, and in direct contact with, two plates of ice, ice-containing soil or ice-containing dispersed medium; then, the specimen is put, together with the plates, into an altitude chamber at a specified negative or positive Celsius temperature. A hydrate-forming gas is injected into the altitude chamber to a pressure exceeding the pressure of the “ice/gas/hydrate” three-phase equilibrium, and the specimen is held in the altitude chamber until equilibrium saturation of the specimen with moisture is achieved. The altitude chamber gas pressure is then decreased to the atmospheric level, the specimen is withdrawn and weighed, and the equilibrium moisture content of the specimen is determined from the difference between the specimen weights before and after the experiment.
