  • Patent number: 10077388
    Abstract: This invention relates to the use of chloro-trifluoropropenes as refrigerants in negative-pressure liquid chillers and methods of replacing an existing refrigerant in a chiller with chloro-trifluoropropenes. The chloro-trifluoropropenes, particularly 1-chloro-3,3,3-trifluoropropene, have high efficiency and unexpectedly high capacity in liquid chiller applications and are useful as more environmentally sustainable refrigerants for such applications, including the replacement of R-123 and R-11.

  • Patent number: 10035939
    Abstract: The invention relates to a refrigerant composition and its preparation method, which is characterized by the composition of the following weight percentages: 1,1,1-trifluoroethane: 1-3% Difluoromethane: 8-12% Pentafluoroethane: 40-44% 1,1,1,2-tetrafluoroethane: 42-46% N-butane: 2-4%. Compared with the existing technology, the refrigerant composition provided by the present invention can be used to replace R22 and charged directly into such refrigeration and air conditioning systems as household air conditioner/heat pump unit, unitary air conditioners, refrigeration condensing units, water chillers and other. And the present invention is very close to the physical parameters of R22, compatible with the lubricating oil, conduits and components of the existing R22 system and can also be directly charged to replace R22 with a low cost and good refrigeration efficiency and cooling effect. Moreover, this invention will not deplete the stratospheric ozone layer while having a simple preparation method.

  • Patent number: 10015910
    Abstract: A heat pipe includes a binary working fluid including a composition proximate to and less than or equal to the azeotropic point in a thermodynamic phase diagram as a function of the composition of the binary working fluid. Moreover, in a liquid phase of the binary working fluid, a boiling point of the binary working fluid as a function of temperature and the composition in the thermodynamic phase diagram is approximately constant. For example, the boiling point may vary by less than a degree Celsius over a range of compositions proximate to and less than or equal to the azeotropic point. Furthermore, components in the binary working fluid may be fully miscible as a function of the temperature and the composition in the thermodynamic phase diagram, a component in the binary working fluid may include a non-zero dipole moment, and/or the component may form a hydrogen bond with water.
