Mixed fluid heat transfer system optimising regulator - has heat exchangers for branched streams for depletion evaporation and re-enrichment

摘要

The regulating system is used for optimising the economy of a heat transfer system using multimedium mixture as energy carrier. The latent energy of the supplied enriched solution is divided into two streams at the conversion point from hot into cold. These streams are heated in two heat exchangers up to boiling point and then joined. The two new streams are branched and from one of these mixed vapour is driven out by heating in a heat exchanger. The residual liquid is transferred into externally heated heat exchanger in which is carried out final separation of the mixed vapour from the remaining depleted solution. The diversion of the supplied enriched solution is regulated to ensure max. heat feedback.
