Abstract: Disclosed herein is a chiller apparatus containing refrigerant characterized by said refrigerant being HFO-1336mzz that is trans isomer or primarily trans isomer. These chillers may be flooded evaporators or direct expansion evaporators, which utilize either centrifugal or screw compressors. Also disclosed herein are methods for producing cooling comprising evaporating trans-HFO-1336mzz in an evaporator in the vicinity of a body to be cooled, thereby producing cooling. Also disclosed herein is a method for replacing HFC-236fa or CFC-114 refrigerant in a chiller apparatus, said method comprising providing HFO-1336mzz to said chiller apparatus in place of the replaced refrigerant; wherein said HFO-1336mzz is trans isomer or primarily trans isomer.

Abstract: Disclosed herein are chiller apparatus containing cis-HFO-1336mzz. These chillers may be centrifugal chillers or positive displacment (e.g., screw) chillers and may comprise flooded evaporators or direct expansion evaporators. Also disclosed herein are methods for producing cooling comprising evaporating cis-HFO-1336mzz in the vicinity of a body to be cooled.

Abstract: Disclosed herein are compositions comprising lithium bromide, water, and at least one ionic compound. These compositions are useful as working fluids in absorption cycle systems. The ionic compound additive has been demonstrated to reduce crystallization in such absorption cycle systems.

Abstract: An absorption cycle system utilizes an additional absorption circuit in conjunction with a traditional absorption circuit. The absorbent used in the additional absorption circuit could contain an ionic compound, or any absorbent with relatively low crystallization. Mixtures of such absorbent with water remain liquid at temperatures lower than the minimum feasible operating temperature of the traditional lithium bromide water absorbent solutions of the prior art.

Abstract: This invention relates to compositions comprising a refrigerant and at least one ionic compound and/or non-ionic absorbent, and also to devices capable of executing an absorption cycle using such compositions as a refrigerant pair. This invention also provides methods and apparatus for cooling using an absorption cycle comprising a refrigerant, and at least one ionic compound and/or non-ionic absorbent as the absorbent.

Abstract: Disclosed herein are compositions comprising at least one ionic liquid and at least one fluoroolefin. Such compositions may be useful as absorbent/working fluid pairs in absorption cycle systems for providing cooling or heat.

Abstract: An absorption power cycle system utilizes the working fluid from an absorption circuit to produce mechanical work. Such a system is useful in a wide range of absorption cycle applications.
