recuperator prevent pressure drop to normal operation because the vacuum is produced at home (effective exhaust is stronger than supply) . GHE Causing the need for additional fans supporting and electricity consumption loss final efficiency.
rekuperator kuzuia shinikizo kushuka kwa huduma ya kawaida kwa sababu utupu ni zinazozalishwa nyumbani (kutolea nje ufanisi ni nguvu kuliko ugavi) . GHE Kusababisha haja ya mashabiki ziada kusaidia na umeme matumizi ya hasara ya mwisho ufanisi .
