多重分离系统空调机和空对空热泵.性能额定值的测试

[中文适用范围]： 本文件规定了冷却式空调机和空气 - 空气热泵的性能测试、标准条件及测试方法，用于确定容量和效率等级。本文件适用于以下设备：基本多联机系统、模块化多联机系统和模块化热量回收多联机系统。这些多联机系统包括带有无风管和/或有风管内机（带内置风扇）以及不带风扇的内机的空气 - 空气系统。本文件仅限于：住宅、商业和工业用分体式空调机和热泵；出厂制造、电气驱动并使用机械压缩的；单回路和多回路分体式系统，利用一个或多个压缩机，外机控制步骤不超过两步；或单制冷剂回路分体式系统，利用一个或多个变速压缩机或其他压缩机组合，通过三个或更多步骤改变系统容量。这些分体式系统设计用于一个或多个外机与两个或多个可独立操作的内机的组合，且此类模块化系统能够在同一系统内将一个或多个内机回收的热量转移给其他内机。本文件中的测试和评级要求基于匹配组件的使用。本文件不适用于以下设备的评级和测试：a) 水冷或水源设备；b) 具有冷凝器排风管的移动（单风管）设备；c) 不构成完整制冷系统的单个组件；d) 使用吸收式制冷循环的设备；e) 额定功率小于 8 kW 且设计在外部静压小于 25 Pa 下运行、由单个温控器/控制器控制的有风管空调机和/或有风管热泵（参见 ISO 5151）；f) 利用一个或多个制冷系统、一个外机和一个或多个内机并由单个温控器/控制器控制的多联机系统（参见 ISO 5151 或 ISO 13253）。本文件未涵盖季节性效率或季节性部分负荷性能的确定，因为某些国家可能需要这些性能，以更好地指示实际运行条件下的效率。 注：本文档中术语“设备”和“系统”指“多联机空调机”和/或“多联机热泵”。 [外文原描述]： ISO 15042:2017 specifies the performance testing, the standard conditions and the test methods for determining the capacity and efficiency ratings of air-cooled air conditioners and air-to-air heat pumps. ISO 15042:2017 is applicable to the following equipment: -― basic multi-split systems, modular multi-split systems and modular heat recovery multi-split systems. These multi-split systems include air-to-air systems with non-ducted and/or ducted indoor units with integral fans and indoor units supplied without fans. ISO 15042:2017 is limited to: - residential, commercial and industrial split-system air conditioners and heat pumps; - factory-made, electrically driven and use mechanical compression; - single- and multiple-circuit split-systems which utilize one or more compressors with no more than two steps of control of the outdoor unit; or - split-systems with a single refrigeration circuit which utilize one or more variable-speed compressors or alternative compressor combinations for varying the capacity of the system by three or more steps. These split-systems are designed to operate with a combination of one or more outdoor units and two or more indoor units designed for individual operation, and such modular systems are capable of transferring recovered heat from one or more indoor units to other units in the same system. The requirements of testing and rating contained in this document are based on the use of matched assemblies. ISO 15042:2017 is not applicable to the rating and testing of the following: a) water-cooled or water source equipment; b) mobile (single-duct) units having a condenser exhaust duct; c) individual assemblies not constituting a complete refrigeration system; d) equipment using the absorption refrigeration cycle. e) ducted air conditioners and/or ducted heat pumps, rated at less than 8 kW and intended to operate at external static pressures of less than 25 Pa, controlled by a single thermostat/controller (refer to ISO 5151); f) multiple split-system utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units, controlled by a single thermostat/controller (refer to ISO 5151 or ISO 13253). ISO 15042:2017 does not cover the determination of seasonal efficiencies or seasonal part-load performances, which can be required in some countries because they provide a better indication of efficiency under actual operating conditions. NOTE Throughout this document, the terms "equipment" and "systems" mean "multi-split air conditioners" and/or "multi-split heat pumps".
