Kitchen hood air circulation system has an adjustable base and a structured outflow and inflow at the plate heat exchanger to use the heat of the exhaust air to raise the fresh air inflow temp

摘要

The air flow system with heat recovery, such as a kitchen hood with a high specific suction power, extracts the air from the kitchen for heat recovery. The base (2A) of the assembly is adjusted, together with the spacers (6), to set the height of the gaps (7A,7B). The plate heat exchanger (1A) is positioned so that the exhaust air flows vertically upwards from below (8E,8F), and the feed air (9A,9B) has a horizontal flow.
