This standard applies to a. absorption packages used to chill and/or heat water@ as defined in Section 3@ Definitions@ and b. testing that will occur where proper instrumentation and load stability can be provided. c. It is not the intent of this standard to provide for testing in typical field installations@ where steady-state conditions are often difficult to achieve and adequate provisions for measurement are not made. PURPOSE The purpose of this standard is to prescribe 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.
