KERS can work in three different modes:
Ventilation:
the unit works continuously in extraction.
Injection:
the unit operates continuously in injection.
Heat recovery:
the unit operates alternately in two phases of 65 seconds each:
2.1.1
Phase 1 - stale hot air is extracted from the room. As it flows through the ceramic heat exchanger, it heats
it. Thus it transfers up to 91% of the thermal energy. In 65 seconds the exchanger is heated and the unit
switches to phase 2.
2.1.2
Phase 2 - fresh air flows from the outside through the hot ceramic exchanger which heats the air down to
room temperature. In 65 seconds t
he ceramic exchanger cools down and the unit switches to “phase 1”.
