JONKER, A.S.  y  GREYVENSTEIN, G.P.. Simulation investigation into the comparative performance of different vacuum ice refrigeration systems and a conventional ammonia system for the cooling of deep mines. R&D j. (Matieland, Online) [online]. 1999, vol.15, pp.1-8. ISSN 2309-8988.

A simulation model for vacuum-ice refrigeration systems was developed. The model was extended to deal with three variants of the vacuum-ice refrigeration system, i.e. single-stage compression, two-stage compression, and a hybrid system. The model was then used to compare the performance of these systems with a conventional ammonia refrigeration system. The hybrid vacuum-ice system was found to have the highest COP of the vacuum-ice systems, while the COP of the ammonia system was higher than those of any of the vacuum-ice systems.
