Altogether, 4 locations of mobile radio stations are currently equipped with hybrid ventilation systems for cooling the technical infrastructure. Cooling room ventilation and venting are carried out with a wind-driven fan system. In addition, an integrated computer-controlled electric motor can be used in the fan head at dead calm.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

When the fan is open, the fan is driven by the natural wind energy and the waste heat is extracted from the interior of the building. No electrical energy is required to operate, approximately 60% of the total cooling time is covered per year. The motor drive serves as a safety back-up when wind speeds are not sufficient. The energy consumption in this case is approximately 315 kWh p.a. Each year and installed plant, around \u20ac 1.800, – of operating costs are saved. This is achieved by an operating hours reduction of the air-conditioning systems of about 75% per year. The amortization period of the investment in this concrete project is around 3.6 years.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
