A Study on Refrigerant Irregular Emission from China Mobil Air Conditioning Vehicles Based on JD Power Result

The purpose of this article is to study current refrigerant emission levels in China with reasonable accuracy of the first year vehicles. This is an initial survey on refrigerant irregular emissions based on JD Power investigation and warranty data from OEMs in 2008. Totally 49 brands and 8881 vehicles were included for the study, covering almost all the kinds of passenger vehicles in China market.

Irregular emissions represent the refrigerant losses due to accidents and other environmental-related failures of the mobile AC system. This paper also wants to draw people's attention on irregular refrigerant emissions related to system design and reliability which is not focused yet.

According to the calculation of irregular emissions from China vehicles by J.D Power result, the irregular emission is 5.8 g/yr, which can be a reliable number used in the GREEN-MAC-LCCP© model for China vehicles' refrigerant emissions.
