ASHRAE Standard 182 prescribes a method of testing absorption water-chilling and water-heating packages to verify capacity and thermal energy input requirements at a specific set of operating conditions.This standard applies to absorption packages used to chill and/or heat water, as defined by the standard, and to testing that will occur where proper instrumentation and load stability can be provided.The standard does not provide for testing in typical field installations, wheresteady-state conditions are often difficult to achieve and adequate provisions for measurement are not made.
