The March 2022 paper, published by UL Solutions, outlines the methodology and findings of a comprehensive refrigerant release testing project conducted at UL Solutions laboratories in the US. The study specifically incorporates furniture with significant displacement volume concerning a room’s overall volume, including cabinets, drawers, wardrobes, and armoires. The results lead to the conclusion that furniture and structures with hollow interiors have minimal impact on calculating room volume. Furthermore, the observations affirm that refrigerant behaves similarly to other fluids, flowing rapidly in the presence of a pressure differential.
