The present invention relates to a chiller of the type using water as refrigerant and aqueous lithium bromide or the like as absorbant, wherein 2-ethyl n-hexanol or a similar compound is used as additive to said solution to improve heat transfer in the absorber, comprising a separator for separating a large part of the additive from said solution, said separator being located between the exit of the lithium bromide solution from the absorber and between the heat exchanger in the conduit leading to the generator. According to one embodiment, the separator operates on gravity separation. According to one embodiment, the separator comprises a vessel large enough for substantially slowing down the velocity of flow of the solution, provided with inlet means at its lower part, outlet means at its upper part for a small part of the solution substantially enriched respective said additive, and an outlet at its lower part for the bulk of the solution, depleted of part of the additive.

A process for operating the refrigeration cycle of a chiller of the type using water as a refrigerant and lithium bromide or the like as an absorbant and 2ethyl n-hexanol as an additive, comprising the steps of: removing an aqueous lithium bromide solution containing 2-ethyl n-hexanol from an absorber; continuously separating the solution into a hexanol depleted phase and a hexanol enriched phase; recycling the enriched phase to the absorber; and feeding the alcohol depleted phase through a heat exchange means to a generator, said depleted phase being in heat exchanger relationship with lithium bromide fed from the generator to said absorber through said heat exchange means.
