Ammonia refrigerating plant for the manufacture of pumpable water-ice mixtures and liquid carbon dioxide for the cooling of display cabinets.

[In German. / En allemand.]

Summary

Preliminary analyses of the described plant have shown that the yearly operation costs for use of a refrigerating plant using natural refrigerants in a supermarket are on the same level that traditional two-stage refrigeration plants. Investments are also nearly the same. The production of an ice mixture is technically possible. Different pressure losses are stated according to the additive used. A combination of the ice mixture and chilled water accumulation may reduce operation costs.
