A Review of Heat Recovery in Ventilation

The purpose of the article was to present information on heat recovery in ventilation systems and highlight what has not been sufficiently researched this regard. A lot can be found methods exchangers for centralized systems. Decentralized, façade cyclical supply exhaust air have researched. It is known that these devices are sensitive influence wind temperature, hence may ineffective their case. literature describes aspect depending location climatic zones, number degree days (HDD).
