Field notes
The homepage describes a CFD model and says it was validated against ammonia experiments; the research section is also described as covering design-basis studies. It names hot-gas defrost as a common context in ammonia refrigeration and lists steam and power, process plant, and CO₂ sequestration among application areas.
