Glossary

purge A device used to remove air and other noncondensable gases that may leak into the low-pressure absorption chiller.

refrigerant A substance used to absorb and transport heat for the purpose of cooling. In a large absorption water chiller, the refrigerant is distilled water.

saturation temperature The temperature, for a given concentration, at which the solution contains the most salt that it can hold. If the temperature drops any further, the salt begins to leave the solution in a solid form (crystallize).

single-effectA type of absorption chiller that uses a single generator.

throttling pipe A type of expansion device used in absorption water chillers. It is a section of pipe with an orifice inside.

variable-speed drive See adjustable-frequency drive.
