ADVANCED CONTROLLING SYSTEM WITHOUT ELECTRICAL POWER AND ELECTRONIC SIGNAL FOR ELEVATING AN EXHAUST EFFICIENCY OF WASTE GAS IN CHIMNEY

摘要

PURPOSE: A wireless exhaust system formed in a chimney of a multi-story building is provided to control the air currents within a chimney to flow upward regardless of the height of the building. CONSTITUTION: A wireless exhaust system formed in a chimney of a multi-story building comprises a ventilation machine controller(C1) and a controller(C2). If a positive pressure sensing value and a differential pressure value exceeds a specified amount of pressure, the ventilation machine controller supplies power to a ventilation machine motor(M1) which rotates a ventilation machine(3). If negative sensing value exceeds a specified amount of pressure, the controller controls an electric damper(M2) and an external air guide duct(4) is closed.
