    摘要： Compressor arrangement for generating compressed air by means of a motor-operator compressor unit (2), downstream of which at least one cooler unit (4a, 4b) is connected for cooling the generated compressed air, which enters the cooler unit (4a, 4b) via at least one inlet (5), flows there through a cooling structure (6), around which cooling air flows, from a plurality of cooling passages connected in parallel and leaves the cooler unit (4a, 4b) via at least one outlet (7), wherein bypass means for avoiding freezing of the cooler unit (4a, 4b) at low ambient temperatures are provided between the inlet (5) and the outlet (7) of the cooler unit (4a, 4b), wherein a permanently open bypass pipe (9) is provided as bypass means between the region of the inlet (5) and the region of the outlet (7), the inner cross section of which bypass pipe (9) is matched to the delivery capacity of the compressor unit (2) and to the pressure difference between inlet (5) and outlet (7) in such a way that the bypass pipe (9), at normal ambient temperatures, causes a higher flow resistance than the cooling structure (6), whereas, as freezing of the cooling structure (6) progresses, the compressed air flows increasingly via the bypass pipe (9) in order to maintain the generation of compressed air with minimum loss of cooling and delivery capacity.
