1.1移动空调系统对环境的影响变得越来越重要。用于为系统提供动力的燃油会影响车辆的燃油经济性和二氧化碳的尾气排放。1.2本标准适用于由一个或两个车内空气盘管（蒸发器）、压缩机、膨胀装置、一个机罩下空气盘管（冷凝器）组成的移动式空调系统，1.2.1如果仔细考虑压缩机输入功率的测量，本标准也可用于使用电动压缩机的测量系统。 1.2.2如果仔细考虑了整个车辆系统的空气侧压降，则本标准也可用于包括整个空气处理系统的测量系统。1.2.3如果仔细考虑了整个车辆系统的空气侧压降，则本标准也可用于包括整个前端冷却模块的测量系统。1.2.4如果仔细考虑了驱动系统中泵的功率，则本标准也可用于包括二次冷却回路的测量系统。1.2.5本标准也可用于双蒸发器系统。 1.2.6本标准也可用于带有用于调节电动汽车电池的冷却器的移动空调系统。1.3本标准规定了产生制冷剂部件准确稳态容量和效率数据的程序、仪器和仪表。1.4本标准未规定:1.4.1规定瞬态试验方法，1.4.2提出安全建议。4.3规定移动空调系统的生产测试、规范符合性测试或现场测试。1.5目的1。5.1本标准提供了在稳态条件下测试移动式空调制冷剂系统容量（性能）和效率（COP）的方法。 1.5.2拟定程序旨在为确定移动式空调制冷系统的制冷量（Q）和效率（COP-性能系数）提供最大的重复性和最小的误差。因此，提出了一种“试验板”型设施，将部件组装到一个系统中，并暴露在单独的、单独控制的腔室中的操作条件下。该设施应考虑三种方法来确定系统性能:制冷剂侧、空气侧和量热室。每一方都会进行自己的能量平衡计算，以确定系统的容量。 使用三种方法，而不是通常需要的两种方法，即使蒸发器制冷剂出口为两相，也将保持冗余。在这种情况下，只有空侧和腔室天平可用。但是，如果空气侧散热与制冷剂侧散热正确平衡，则不需要量热室。设计时应确保两种独立的方法能够在两个独立的天平之间提供小于±4.0%的一致性。

1.1 The impact of mobile air conditioning systems on the environment is becoming more important. Fuel used to power the system impacts both fuel economy of the vehicle and tail pipe emissions of carbon dioxide.1.2 This Standard applies to mobile air conditioning systems consisting of one or two in-car air coil (evaporator), a compressor, an expansion device, one under-hood air coil (condenser), and either with or without a liquid to refrigerant evaporator (chiller).1.2.1 This standard can also be used for measuring systems that use electrically driven compressor if measurement of input power to compressor is carefully considered.1.2.2 This standard can also be used for measuring systems that include the entire air handling system if air side pressure drop for the entire vehicle system is carefully considered.1.2.3 This standard can also be used for measuring systems that include the entire front end cooling module if air side pressure drop for the entire vehicle system is carefully considered.1.2.4 This standard can also be used for measuring systems that include a secondary cooling loop if the power to drive the pumps in this system is carefully considered.1.2.5 This standard can also be used for dual evaporator systems.1.2.6 This standard can also be used for mobile air conditioning systems with chillers used to condition the battery of an electric vehicle.1.3 This Standard specifies procedures, apparatus, and instrumentation that will produce accurate steady state capacity and efficiency data for refrigerant components.1.4 This Standard does not:1.4.1 Specify transient test methods,1.4.2 Make recommendations for safety1.4.3 Specify tests for production, specification compliance, or field testing of mobile air conditioning systems.1.5 Purpose1.5.1 This Standard provides a method of testing the capacity (performance) and efficiency (COP) of mobile air conditioning refrigerant systems under steady state conditions.1.5.2 The procedure proposed is designed to give maximum repeatability and minimum error in determining cooling capacity (Q) and efficiency (COP - Coefficient of Performance) of the refrigeration system of the mobile air conditioner. For that reason a "breadboard" type facility is proposed in which components are assembled into a system and exposed to operating conditions in individual, separately controlled chambers. The facility should allow for three methods to determine system performance: refrigerant side, airside, and calorimetric chambers. Each side yields its own energy balance calculation to find the capacity of the system. With the three methods used, instead of two as typically required, redundancy will be maintained even when the evaporator refrigerant exit is two phase. In this case only the airside and chamber balances are available. However, the calorimetric chamber is not required provided the airside heat rejection is properly balanced with the refrigerant side heat rejection. The design should be made so that two independent methods could provide agreement of less than ±4.0% between two independent balances.
