HEAT RECOVERY

摘要

Air supplied to the room is pre-heated by the air being extracted via the integrated heat exchanger block. The ventilation unit automatically adjusts the ventilation rate as it receives signals from interconnected sensors. When the signal is received, the fans vary their speed proportionally or on a trickle and boost principle.rnThe unit is fitted with two fans with speed control circuit so that volume flow rates can be pre-set. A plate heat-exchange constructed from aluminium is used to provide up to 70 per cent heat recovery.
