Embodiment Construction
[0028] The underground substation adopts the method of natural air supply and mechanical exhaust. Each ventilation room is evenly distributed with at least one ventilation duct. When the fan of the ventilation duct is turned on, the air is exhausted, and the room is ventilated at the same time. When the wind force on the exhaust side is insufficient, The speed of indoor ventilation will slow down, so we can judge whether the entire ventilation duct is healthy by detecting whether the exhaust outlet at the end of the ventilation duct (located on the side of the exhaust shaft) reaches the design wind speed and wind direction.
[0029] Please check figure 1 , an underground substation HVAC ventilation system failure monitoring system, which includes at least one light emitting diode 10 and a micro-wind generator 20 for detecting the wind force at the air outlet at the terminal air outlet of the ventilation duct to be tested, the miniature The wind power generator 20 has a fan str...
