Establishes methods of rating the performance of factory-made liquid-chilling packages using the vapour compression cycle.

This Standard sets out a procedure for rating liquid-chilling packages used in applications with temperatures as described in Clause 5.3 and as defined in Clause 4.12. This Standard covers air- and water-cooled liquid-chilling packages of cooling capacity 350 kW and above.This Standard does not cover - (a) liquid-chilling packages driven by other than electric motors;(b) air-cooled liquid-chilling packages with centrifugal fans;(c) liquid-chilling packages with remote condensers; and(d) liquid-chilling packages for fluids other than water.This Standard covers full-load and part-load ratings to allow for an energy analysis of the unit in different applications.
