Cold

It is possible to take advantage of the useful heat produced by Rank® equipment for cold production through various technologies. In this way, it is possible to form trigeneration systems.

Thermally activated cooling technologies

Water – lithium bromide absorption

The most commonly used cycle is that of water-lithium bromide for having greater efficiency. Lithium bromide is used because it has a great capacity to absorb water and because it can be dehydrated by heat.

Ammonia – water absorption

The ammonia-water cycle is used, although it has lower energy efficiency, because it has the advantage of being able to achieve temperatures below 0ºC.

Adsorption

The principle of operation is similar to that of an absorption system, although in this case the absorbent is not a liquid, but a solid.
