For SI: 1 ton = 3517 W, 1 British thermal unit per hour = 0.2931 W, °C = [(°F) - 32]/1.8.

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.
