Mixtures of Organic Working Fluids

• A siloxane is any chemical compound composed of units of the form R2SiO, where R is a hydrogen atom or a hydrocarbon group.

• They belong to the wider class of organosilicon compounds.

• Hexamethyldisiloxane is a chemical compound with the formula O[Si(CH3)3]2.

Superheat Cycles

• For heat exploitation at comparatively high temperature, a saturated cycle requires a working fluid with a very high critical temperature which implies an unrealistically low condensation pressure.
