    Abstract: The present invention provides systems and methods for transferring heat using a variable composition organic heat transfer fluid that remains liquid over a wide operating temperature range useful for solar heating applications. Variable composition heat transfer fluids of the present invention comprise a miscible mixture, optionally a completely miscible mixture, of a high boiling point component selected for its beneficial high temperature physical properties, and a low freezing point component selected for its beneficial low temperature physical properties. In some embodiments, the low freezing point component is removed from the heat transfer fluid as the heat transfer fluid is heated, for example by being removed in the vapor phase, thereby selectively varying the composition and physical properties (e.g., vapor pressure, boiling point, etc.) of the heat transfer fluid as a function of temperature.

  • Patent number: 9003797
    Abstract: A method is provided for converting heat from a heat source to mechanical energy. The method comprises heating a working fluid using heat supplied from the heat source; and expanding the heated working fluid to lower the pressure of the working fluid and generate mechanical energy as the pressure of the working fluid is lowered. The method is characterized by using a working fluid comprising HFC-245eb and optionally Z-HFO-1336mzz. A power cycle apparatus containing a working fluid to convert heat to mechanical energy is also provided. The apparatus is characterized by containing a working fluid comprising HFC-245eb and optionally Z-HFO-1336mzz. A working fluid comprising HFC-245eb and optionally Z-HFO-1336mzz is also provided. The working fluid (i) further comprises E-HFO-1336mzz, (ii) has a temperature above its critical temperature, or both (i) and (ii).

  • Patent number: 9005471
    Abstract: A heat transfer fluid comprising a carrier fluid and a nano-additive is provided. The heat transfer fluid is manufactured by dispersing the nano-additive in the carrier fluid. The nano-additive comprises nano-particles having a porous structure that provides dispersion stability of the nano-additive in the heat transfer fluid. The nano-additive structure has an aspect ratio of about 1.0 to about 10,000, a porosity of about 40% to about 85%, a density of about 0.4 g/cc to about 3.0 g/cc, an average pore diameter of about 0.1 nanometer to about 100 nanometers, and a specific surface area of about 1 m2/g to about 4000 m2/g. The nano-additive increases the heat transfer efficiency of the heat transfer fluid and also reduces the moisture content of the heat transfer fluid.
