	Refrigerant blends containing HCFCs

Introduction

Refrigerant blends containing HCFCs A blend is a refrigerant consisting of mixtures of two or more different chemical compounds, often used individually as refrigerants for other compounds.

It is important for National Ozone Units to be able to identify refrigerant blends that contain HCFCs during the data collection stage of HCFC Phase Out Management Plans to establish national HCFC consumption baselines. It is also vital for customs officers to be able to identify such blends as part of their enforcement of import/export licensing systems.

How to use this list

The following table lists all such blends, with the HCFC components highlighted in bold. For ease of identification, another table at the end of this page lists the ASHRAE refrigerant numbers ("R-") and the common names.

To see a list of the commercial trade names of refrigerants that contain a specific blend, click on the ASHRAE number in the left column. To see a full list of trade names of products containing HCFCs (in blends and as single components), click here.
