NR = No requirement. a Chapter 6 contains a complete specification of the referenced standards, which includes test procedures, including the referenced year version of the test procedure. b The requirements for centrifugal chiller shall be adjusted for nonstandard rating conditions per Section C403.3.2.4 and are applicable only for the range of conditions listed there. The requirements for air-cooled, water-cooled positive displacement and absorption chillers are at standard rating conditions defined in the referenced test procedure. c Both the full load and IPLV.IP requirements must be met or exceeded to comply with this standard. When there is a Path B, compliance can be with either Path A or Path B for any application. d NA means the requirements are not applicable for Path B and only Path A can be used for compliance. e FL is the full-load performance requirements, and IPLV.IP is for the part-load performance requirements. f This table is a replica of ASHRAE 90.1 Table 6.8.1-3 Water-Chilling Packages — Minimum Efficiency Requirements.
