  • Page 14: Heat Recovery Systems

    5. HEAT RECOVERY SYSTEMS 5.1 PLATE HEAT EXCHANGER In the plate heat exchanger, the warm extract air and the cool fresh air, separated by thin plates, pass each other in counter-flow. No mixing of the two air streams takes place. Therefore, the transmission of dirt, odours, moisture, bacteria, etc. is impossible. Heat transmitted from extract air to fresh air purely by conduction because of the temperature difference between the two air streams: the warm extract air cooled down and the cool fresh air heated up.
