Indoor parking lots allow more vehicles to be parked in buildings such as shopping malls, hospitals, business centers. The excess carbon monoxide produced by vehicles in indoor parking lots poses serious dangers for human health. For this, a serious ventilation system should be studied in closed parking lots.Jjet fan ventilation systems provide cost and time savings in car park ventilation systems. HAVKON offers various projects on jet fan automation. In jet fan automation, HAVKON makes many applications such as zone creation technique, air flow direction determination, fire and smoke evacuation scenario.The hygroscopic effect in products produced in various industries and enterprises, weight reduction of products such as fruits and vegetables, electrical discharge events caused by electrostatic electricity accumulations, and the decrease in efficiency due to worsening of employee welfare is directly proportional to the precise control of ventilation and air conditioning systems. HAVKON designs and implements the most efficient scenarios for industry and businesses.
