标准摘要
[中文适用范围]： 本文件的目的是制定指南，用于确定 SAE J1116 中定义的越野@自走式作业机械和 ANSI/ASAE S390 中定义的农用拖拉机的关键 R134a 制冷剂充注量。它将制定一个最小到最大的制冷剂充注量范围，在该范围内，暖通空调系统可以保持正常运行。设备的运行条件和特性将影响最佳充电。由于这些条件和特性因应用而异，因此应仔细考虑以确定 HVAC 系统的最佳 R134a 制冷剂充注量。 [外文原描述]： The purpose of this document is to establish guidelines for determining the critical R134a refrigerant charge for off-road, self-propelled work machines as defined in SAE J1116 and Agricultural Tractors as defined in ANSI/ASAE S390. It will develop a minimum to maximum refrigerant charge range in which the HVAC system can maintain proper operation. Operating conditions and characteristics of the equipment will influence the optimum charge. Since these conditions and characteristics vary greatly from one application to another, careful consideration should be taken to determine the optimum R134a refrigerant charge for the HVAC system.Cross Reference:
