Provided is an air supply system and a control method for the air supply system that can reduce the load when a compressor begins operating. This air supply system (10) comprises: an air drying circuit (11) that is provided between a compressor (4) for sending compressed air and an air tank (30) for storing compressed dry air, and that comprises a filter (17) containing a drying agent for capturing moisture; and an ECU (80) that controls the air drying circuit (11). The ECU (80) is equipped with a supply operation in which the compressed air sent from the compressor (4) is passed through the filter (17) and compressed dry air is stored in the air tank (30), and a regeneration operation in which the compressed dry air stored in the air tank (30) is passed through the filter (17) in the reverse direction and the drain-off that passes through the filter (17) is discharged from a drain discharge port (27). After executing the regeneration operation, the ECU (80) performs a compressor assistance operation in which the compressed dry air stored in the air tank (3) is passed through the filter (17) in the reverse direction and filled into the air drying circuit (11).
提供一种能够降低压缩机在运转开始时的负荷的空气供给系统和空气供给系统的控制方法。空气供给系统(10)具备:空气干燥回路(11),其设置在送出压缩空气的压缩机(4)与贮存压缩干燥空气的气罐(30)之间,具有包括捕捉水分的干燥剂的过滤器(17);以及ECU(80),其控制空气干燥回路(11)。ECU(80)具备:供给动作,其使从压缩机(4)送出的压缩空气通过过滤器(17)来将压缩干燥空气贮存于气罐(30);以及再生动作,其使贮存于气罐(30)的压缩干燥空气沿逆方向通过过滤器(17)来将通过了过滤器(17)的排液从排液排出口(27)排出,ECU(80)在执行再生动作之后执行压缩机辅助动作,所述压缩机辅助动作使贮存于气罐(30)的压缩干燥空气沿逆方向通过过滤器(17)填充到空气干燥回路(11)。
