e. is rated from 0.4 to 1600 kW at a frequency of 60 Hz; and f. conforms to Sections 8.1, 8.2, and 8.3 of IEC 60034-12 (edition 2.1) requirements for starting torque, locked rotor apparent power, and starting.
IEC Design N motor: an electric motor that
a. is an induction motor designed for use with three-phase power; b. contains a cage rotor; c. is capable of direct-on-line starting; d. has 2, 4, 6, or 8 poles; e. is rated from 0.4 to 1600 kW at a frequency of 60 Hz; and f. conforms to Sections 6.1, 6.2, and 6.3 of IEC 60034-12 (edition 2.1) requirements for torque characteristics, locked rotor apparent power, and starting.
indirectly conditioned space: see space .
indoor grow: a space, other than a greenhouse, used exclusively for horticultural production, cultivation, or maintenance.
indoor pool dehumidifier: a type of air-cooled or water-cooled electrically operated vapor compression refrigeration system, factory assembled as a single package or split system, that includes an indoor cooling/ dehumidifying coil, an air reheat coil, one or more compressors, and an air-moving device. It may also include a refrigerant heat recovery unit, an auxiliary refrigerant condenser, an economizer, and an air-to-air heat recovery device. It shall provide the function of dehumidification, air circulation, and air reheating and may include the function of air-cooling, air-cleaning, pool water heating, and air-to-air heat recovery.
ineffective panel surface: see thermally ineffective panel surface .
installed exterior lighting power: the power in watts of all site, landscape, and building lighting systems for exterior luminaires .
installed interior lighting power: the power in watts of all general, task, and furniture lighting systems for interior luminaires .
insulated metal panel: a factory-manufactured panel consisting of metal facings, an insulative core, and a panel joint intended for use in an assembly forming an exterior wall, an exterior wall covering, or a roof cov- ering of a building envelope .
integrated energy efficiency ratio (IEER): a single-number figure of merit expressing cooling part-load EER efficiency for commercial unitary air-conditioning and heat-pump equipment on the basis of weighted operation at various load capacities for the equipment .
integrated part-load value (IPLV .IP ): a single-number figure of merit based on part-load EER expressing part-load efficiency for air-conditioning and heat-pump equipment on the basis of weighted operation at various load capacities for the equipment .
integrated seasonal coefficient of performance (ISCOP): a seasonal efficiency number that is a combined value based on the formula listed in AHRI Standard 920 of the two COP values for the heating season of a DX-DOAS unit water or air source heat pump, expressed in W/W.
integrated seasonal moisture removal efficiency (ISMRE): a seasonal efficiency number that is a combined value based on the formula listed in AHRI Standard 920 of the four dehumidification moisture removal effi- ciency ( MRE ) ratings required for DX-DOAS units, expressed in lb of moisture/kWh.
interior lighting power allowance: see lighting power allowance .
isolation devices: devices that isolate HVAC zones so that they can be operated independently of one another. Isolation devices include, but are not limited to, separate systems, isolation dampers, and controls providing shutoff at terminal boxes.
IT equipment energy: annual energy used for computer storage and network equipment along with supplemental equipment represented by the uninterruptible power supply (UPS) output calculated in accordance with industry-accepted standards (see Informative Appendix E).
joist, steel: any structural steel member of a building or structure made of hot-rolled or cold-rolled solid or open-web sections.
kilovolt-ampere (kVA): where the term kilovolt-ampere is used in this standard, it is the product of the line current (amperes) times the nominal system voltage (kilovolts) times 1.732 for three-phase currents. For
