Problems solved by technology

This temperature glide affects the temperature difference that drives the heat transfer in the heat exchanger
In addition, there are mass transfer effects due to differences in the concentration of components in the liquid and gas phases
It is generally found that refrigerant mixtures with large temperature glides are not suitable for shell and tube heat exchangers

Embodiment Construction

[0024] Refrigerant compositions, methods of making the same, and / or methods of using the same are described herein.

[0025] In some embodiments, the refrigerant composition includes a binary mixture. In one embodiment, the binary mixture is a substitute for R123.

[0026] In some embodiments, the refrigerant composition includes a mixture of three refrigerants.

[0027] In some embodiments, the refrigerant composition includes two components comprising three refrigerants.

[0028] In some embodiments, the refrigerant composition includes a two-component mixture, wherein one of the components is a refrigerant mixture that, when originally combined, is considered an azeotrope, azeotrope, near-azeotrope, or the like. In some embodiments, the refrigerant mixture is two refrigerants. This refrigerant mixture is considered to be a first component that exists as an azeotrope or near azeotrope and is then combined with a second component that is another refrigerant. In some embod...

Abstract

Methods of using refrigerant compositions and systems thereof are described. In particular, methods of using refrigerant compositions and systems thereof, include refrigerant compositions including a two component blend. One of the components is a refrigerant blend that, when first combined, is considered an azeotropic blend, azeotrope, near azeotropic, or the like. This component is one component of the two components of the resulting refrigerant composition, which is combined with a second component being another refrigerant.

Description

technical field [0001] The disclosure herein relates to refrigerant compositions that can be used, for example, in refrigeration, air conditioning, and / or heat pump systems, such as can be added to a heating, ventilation, and air conditioning (HVAC) system or unit. Background technique [0002] When a zeotropic mixture is in equilibrium, it has different concentrations of components in the liquid and gas phases. The result is that at a given pressure, the dew point temperature (the temperature at which condensation first begins) is different from the bubble point temperature (the temperature at which evaporation or bubbles first begin to form). The difference between dew point and bubble point is called "temperature glide". This temperature glide affects the temperature differential that drives the heat transfer in the heat exchanger. In addition, there are mass transfer effects due to differences in the concentrations of components in the liquid and gas phases. It is gen...
