ALTERNATE REFRIGERANT CONSISTENCY CRITERIA FOR USE IN MOBILE AIR CONDITIONING SYSTEMS

1993-06-01

HISTORICAL

J1658_199306

This SAE Recommended Practice applies to refrigerant blends (multicomponent refrigerants) intended for use as retrofit refrigerants to replace CFC-12 (R12) in mobile air conditioning systems. Since the composition of non-azeotropic refrigerant mixtures changes as refrigerant is lost, either through the vapor phase or the liquid phase, the method of charging air conditioning systems is important. The purpose of this document is to determine the proper refrigerant phase, liquid or vapor, for system charging by relating system performance changes to the charging method. This document is complete only when combined with the requirements of SAE J1657.

HFC-134a Mobile Air Conditioning System Emission Chart

2007-07-12

HISTORICAL

J2727_200707

The original SAE J2727 “Leakage Chart” provided a rating system for comparing mobile A/C systems and was not intended to define mobile A/C system refrigerant leakage. It had been developed from industry experience of expected system refrigerant leakage based upon currently available technologies. The new “System Emissions Chart” now contained in this revision is intended to serve as a means of estimating the annual refrigerant emissions 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 new chart includes automotive compressor technologies, for conventional mobile air conditioning systems as well as fully hermetic compressors.

J953_199902

The scope of this SAE Recommended Practice is to establish uniform test procedures for passenger cars, to determine whether the system is defined as a defroster or defogger, and to establish minimum performance requirements for each system. A defroster for purposes of this practice is a system which will remove moisture and/or frost from the interior surface of the backlight at −18 °C. A defogger is a system which will remove moisture and/or fog from the interior surface of the backlight at 4 °C. The test procedure is intended to simulate actual conditions by utilizing either a cold room with an appropriate device to introduce air flow over the backlight or a sufficiently large wind tunnel with ambient temperature control. The test procedure and the minimum performance requirements are based on currently available engineering data.

J902_200307

This SAE Recommended Practice provides a test procedure and performance guideline for evaluating passenger vehicle windshield defrosting systems. It is limited to results of tests that can be conducted on uniform test equipment in commercially available laboratory facilities. The current engineering practice prescribes that for laboratory evaluation of defroster systems, a known quantity of water shall be sprayed on the windshield to form an ice coating and then melted by the defroster under specific vehicle operating conditions. The procedure provides uniform and repeatable laboratory test results, even though under actual conditions such a coating would be removed by scraping before driving the vehicle. The performance obtained, therefore, does not directly relate to actual driving conditions, but serves as a laboratory performance indicator for comparing test results within or between systems.

Current industry standards do not exist for determining refrigerant emissions from mobile air conditioning systems. Test procedures are not common between production component suppliers in establishing leakage values. This “System Leakage Chart” has been developed from industry experience of expected refrigerant leakage gains from system design resulting from technology changes. It provides a rating value of various technologies that are currently available. The “Leakage Chart” can be expanded as new technologies are offered and/or developed. This document provides the information to develop an Excel file template “Leakage Chart” for making system analysis. It is not the intent of this Standard to define the refrigerant emissions from a mobile air conditioning system. It is to only define a system rating based upon the technology used.
