    1. a.The requirements for centrifugal chiller shall be adjusted for nonstandard rating conditions per Section 6.4.1.2.1 and are only applicable for the range of conditions listed in AHRI 550/590. The requirements for air-cooled, water-cooled positive displacement and absorption chillers are at standard rating conditions defined in the reference test procedure.

    2. b.Both the full load and IPLV 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.

    3. c.Section 11 contains details for the referenced test procedure, including the referenced year version of the test procedure.

    4. d.NA means the requirements are not applicable for Path B and only Path A can be used for compliance.

    5. e.FL is the full-load performance requirements and IPLV is for the part-load performance requirements.

    6. f.Centrifugal chillers that are not designed for operation at AHRI Standard 550/590 test conditions of 44°F leaving chilled-fluid temperature and 2.4 gpm/ton evaporator fluid flow and 85°F entering condenser-fluid temperature with 3.0 gpm/ton condenser-fluid flow (and thus cannot be tested to meet the requirements of Table B-3) shall have maximum full-load kW/ton (FL) and NPLV part-load ratings requirements adjusted using the following equations:

      FLadj = FL/Kadj

      PLVadj = IPLV/Kadj

      Kadj = A × B

      where
      FL=full-load kW/ton value from Table B-3
      FLadj=maximum full-load kW/ton rating, adjusted for nonstandard conditions
      IPLV=IPLV value from Table B-3

      • Maximum condenser leaving temperature:115°F

    3. c.Section 11 contains details for the referenced test procedure, including the referenced year version of the test procedure.

    4. d.NA means the requirements are not applicable for Path B and only Path A can be used for compliance.

    1. a.MEF = modified energy factor, a combination of energy factor and remaining moisture content. MEF measures energy consumption of the total laundry cycle (washing and drying). It indicates how many liters of laundry can be washed and dried with one kWh of electricity; the higher the number, the greater the efficiency.

    2. b.WF = water factor (in L/L).

    1. a.Equipment class designations consist of a combination (in sequential order separated by periods (AAA).(BB).(C) of the following:

      (AAA) An equipment family code (VOP = vertical open, SVO = semivertical open, HZO = horizontal open, VCT = vertical transparent doors, VCS = vertical solid doors, HCT = horizontal transparent doors, HCS = horizontal solid doors, or SOC = service over counter)

      (BB) An operating mode code (RC = remote condensing or SC = self contained)

      (CC) A rating temperature code (M = medium temperature [3°C], L = low temperature [–18°C], or I = ice-cream temperature [–9°C])

      For example, “VOP.RC.M” refers to the “vertical open, remote condensing, medium temperature” equipment class.

    2. b.V (m3) is the volume of the case, as measured in AHRI Standard 1200, Appendix C.

    3. c.TDA (m2) is the total display area of the case, as measured in AHRI Standard 1200, Appendix D.

    4. d.Open refrigerated display cases shall be covered by field-installed strips, curtains, or doors.
