scope:

This guideline lists the types of refrigerant information recommended as the minimum necessary for refrigerant research and development and commercial application or for use in ASHRAE standards. 

This guideline covers property data for fluids used as refrigerants in HVAC&R applications. These include saturated and unsaturated halocarbons, saturated and unsaturated hydrocarbons, ethers, and inorganic compounds (such as ammonia and carbon dioxide). 

The guideline also addresses

a. basic chemical data,

b. thermophysical property data,

c. materials compatibility data, and

d. safety, health, and environmental information. 

Suggested accuracies and methods that may be used in obtaining the data either are given or have references to applicable standards or other sources

PURPOSE

a. This guideline identifies the types of refrigerant data that may be required by product development and system design engineers, ASHRAE standards, and appropriate codes to successfully apply a refrigerant in refrigeration or air-conditioning equipment.

b. This guideline also provides refrigerant suppliers and researchers with examples of measurement methods, previous research, and desired accuracy levels for various refrigerant properties.
