Moving heat carriers are separated by a wall in recuperators. The majority of heat exchangers are of this type.
In regenerating heat exchangers cold and hot heat carriers contact one and the same surface in turn. Heat is accumulated in the wall during the contact with hot heat carrier and is transferred during the contact with cold heat carrier.
Depending on direction of heat-carriers flow recuperating heat exchangers can be:
- direct flow with parallel movement in one direction
- counter flow with parallel opposite-direction movement
- counter flow with orthogonally related movement of two interacting mediums
Shell heat exchangers are the most common recuperating heat exchangers in industry.
Shell heat exchangers by Astra Refrigeranti S.P.A are tailor-made according to Customer technical requirements.
