The application relates to a compressed air station comprising at least two compressed air components that yield waste heat, wherein each compressed air component is designed either as a compressor, in particular as a screw compressor, or as a refrigeration dryer, wherein at least one of the compressed air components, namely a refrigeration dryer (12), is connected to the exhaust air duct (13), and wherein a further compressed air component is connected to the same exhaust air duct (13), wherein a compressed air refrigeration heat exchanger (23) is provided within the refrigeration dryer (12), in which the compressed air is cooled by way of a refrigerant conducted in a refrigerant circuit (24), wherein the refrigerant circuit (24) comprises a refrigerant compressor (25), a condenser (26), an expansion valve (27) and the compressed air refrigeration heat exchanger (23), wherein the compressed air station further comprises a dryer exhaust air duct (15), which is provided for discharging a cooling air flow that is conducted through the refrigeration dryer (12), and which connects a cooling air outlet (19) of the refrigeration dryer (12) to a refrigeration dryer connection (16) on the exhaust air duct (13), wherein the refrigeration dryer (12) has a fan (20) with a speed-adjustable fan motor (21), and the fan (20) is designed to convey the cooling air flow even against a backpressure currently prevailing in the exhaust air duct (13), wherein the refrigeration dryer (12) has a flow sensor (30) for detecting a respective current value for the cooling air volume flow Vact, and wherein the refrigeration dryer (12) has a controller (22) or interacts with a controller (22), which is configured and designed to record and process the data from the flow sensor (30) and to actuate the fan motor (21) of the fan (20) in such a way that, regardless of the current backpressure in the exhaust air duct (13), the respective current cooling air volume flow Vact follows a setpoint for the cooling air volume flow Vsoll.
A compressed air station comprising at least two compressed air components that yield waste heat, wherein each compressed air component is designed either as a compressor or as a refrigeration dryer,
A method for actuating a fan motor of a fan of a refrigeration dryer within a compressed air station, wherein the compressed air station comprises at least two compressed air components that yield waste heat, wherein each of the at least two compressed air component is designed either as a compressor or as a refrigeration dryer, and at least one exhaust air duct for discharging waste heat from a room, wherein at least one of the at least two compressed air components comprises the refrigeration dryer and is connected to the exhaust air duct, and wherein another one of the at least two compressed air components is connected to the same exhaust air duct,
