SAE J2727-2020 R-134a、R-1234yf 和 R-152a 的移动空调系统制冷剂排放图表的最新版本是哪一版?
最新版本是 SAE J2727-2023 。
The “system emissions chart” contained herein is intended to serve as a means of estimating the annual refrigerant emission rate (grams per year) from new production A/C systems equipped with specified component technologies. It provides emission values for various component technologies that are currently available, and can be expanded as new technologies are commercialized. This document provides the information to develop an Excel file template “system emissions chart” for system emission analysis. The chart includes automotive compressor technologies for conventional mobile air conditioning systems, as well as those using semi-hermetic compressors. This standard can be considered a companion document to SAE J2763. SAE J2727 estimates system emissions, taking into account production assembly variation and accounts for components that are 100% helium leak tested prior to vehicle final assembly.
