Venting control for vehicle degreasing tunnel - has single exchanger to transfer heat and humidity to incoming air

摘要

The degreasing tunnel for vehicles, prior to spraying, is fitted with an air conditioning system which draws off air while maintaining a heat and moisture level inside the tunnel. The air is drawn out by one duct (14) and passed through an enthalpy exchanger (16) in which heat and moisture are given up to the incoming air. The exchanger is driven by a radial fan. Water is thrown into the incoming airstream from the expelled air. A high transfer efficiency is obtained for both thermal and moisture transfer, reducing the running costs of the tunnel.
