Refrigerants in Building Services (TG 21/2022)

Refrigerants are used in the working cycle of virtually all air conditioning systems and heat pumps. The increased use of both comes at a time when the legislative landscape is looking increasingly at restricting or limiting the use of refrigerants that have a direct environmental impact. This places additional considerations on the building services designer with regard to which refrigerants can be used and what the likelihood is of restrictions on their use over time.

This guide covers:

• Current environmental and health and safety legislation affecting refrigerants
• Forthcoming changes to legislation
• Efficiency considerations
• An overview of commonly used refrigerants
• Applications, including DX coils, chillers, split systems, VRF/VRV systems and heat pumps
• Sources of further information

The choice of refrigerants affects various people in the building services industry, hence this guide will be of interest to designers, installers, project managers, building owner/operators and maintenance staff.

The guide is published in partnership with the Building Engineering Services Association.
