1. If more than one efficiency standard is listed for any equipment in , the equipment shall meet all the applicable standards that are listed; and

2. If more than one test method is listed in , the equipment shall comply with the applicable efficiency standard when tested with each listed test method; and

3. Where equipment serves more than one function, it shall comply with the efficiency standards applicable to each function; and

4. Where a requirement is for equipment rated at its "maximum rated capacity" or "minimum rated capacity," the capacity shall be as provided for and allowed by the controls, during steady-state operation.

Exception 1 to Section 110.2(a):

Water-cooled centrifugal water-chilling packages that are not designed for operation at ANSI/AHRI Standard 550/590 test conditions of 44°F leaving chilled water temperature and 85°F entering condenser water temperature with 3 gallons per minute per ton condenser water flow shall have a maximum full load kW/ton and NPLV ratings adjusted using the following equation:

Adjusted maximum full-load kW/ton rating = (full-load kW/ton from Table 110.2-D)/Kadj

Adjusted maximum NPLV rating = (IPLV from Table 110.2-D)/Kadj

Where:

Kadj = (A) × (B)

A = 0.00000014592 × (LIFT)4 – 0.0000346496 × (LIFT)3+0.00314196 × (LIFT)2 – 0.147199 × (LIFT) + 3.9302

LIFT = LvgCond – LvgEvap (°F)

LvgCond = Full-load leaving condenser fluid temperature (°F)

LvgEvap = Full-load leaving evaporator fluid temperature (°F)

B = (0.0015 × LvgEvap) + 0.934

The adjusted full-load and NPLV values are only applicable for centrifugal chillers meeting all of the following full-load design ranges:

• Minimum Leaving Evaporator Fluid Temperature: 36°F

For heat recovery heating chilling package applications where there is simultaneous cooling and heating, compliance with the heating performance heat recover COPHR is only required at one of the four heating AHRI 550/590 (I-P) standard ratings conditions of Low, Medium, Hot-Water 1 or Hot-Water 2. Compliance with the cooling only performance is required as defined in footnotes b and c of Table 110.2-I.
