无管空调和热泵.性能评定和试验

[中文适用范围]： 本文件规定了空气冷却式空调器和空气 - 空气热泵的性能测试、标准条件和测试方法，用于确定容量和效率等级。本文件适用于以下设备：不风管式空气冷却式空调器和不风管式空气 - 空气热泵；或容量小于 8 kW 且设计用于外部静压小于 25 Pa 的风管式空调器和/或风管式热泵。本文件仅限于：住宅、商业和工业用单 package 和分体式空调器和热泵；工厂制造、电力驱动并使用机械压缩的设备；使用单级、多级和可变容量组件的多分体式系统（利用一个或多个制冷系统，一个室外单元和一个或多个室内单元，由单个恒温器/控制器控制）。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) 水源热泵或水冷却式空调器；b) 多分体式系统空调器和空气 - 空气热泵（对此类设备的测试应遵循 ISO 15042）；c) 带有冷凝器排气风管的移动（无窗）单元；d) 不构成完整制冷系统的独立组件；e) 使用吸收式制冷循环的设备；f) 风管式设备，除非本条款另有规定（对此类设备的测试应遵循 ISO 13253）。本文件不包括季节性效率的确定，这在某些国家可能需要，因为它们能更好地指示实际运行条件下的效率。注： throughout this document, the terms "equipment" and "systems" mean "air conditioners" and/or "heat pumps".（ Throughout this document, 本文件中的术语“设备”和“系统”是指“空调器”和/或“热泵”。） [外文原描述]： ISO 5151:2017 specifies 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 5151:2017 is applicable to the following equipment: - non-ducted air-cooled air conditioners and non-ducted air-to-air heat pumps; or - ducted air conditioners and/or ducted heat pumps rated at less than 8 kW and intended to operate at an external static pressure of less than 25 Pa. ISO 5151:2017 is limited to: - residential, commercial and industrial single-package and split-system air conditioners and heat pumps; - factory-made, electrically driven and use mechanical compression; - utilizing single, multiple and variable capacity components; - multiple split-system utilizing one or more refrigeration systems, one outdoor unit and one or more indoor units, controlled by a single thermostat/controller. The requirements of testing and rating contained in this document are based on the use of matched assemblies. ISO 5151:2017 is not applicable to the rating and testing of the following: a) water-source heat pumps or water cooled air conditioners; b) multi-split-system air conditioners and air-to-air heat pumps (follow ISO 15042 for the testing of such equipment); c) mobile (windowless) units having a condenser exhaust duct; d) individual assemblies not constituting a complete refrigeration system; e) equipment using the absorption refrigeration cycle; f) ducted equipment except for those specified in this clause (follow ISO 13253 for the testing of such equipment). ISO 5151:2017 does not cover the determination of seasonal efficiencies, 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 "air conditioners" and/or "heat pumps".
