The invention discloses an automatic control method for a concentrated cooling system and a control system. The automatic control method for the concentrated cooling system comprises the following steps that a weekly coefficient table is constructed, and the weekly coefficient is recorded as M; a variable temperature coefficient is constructed, and the variable temperature coefficient is recorded as N; the yesterday cold selling quantity is obtained, and the yesterday cold selling quantity is recorded as Hs; and the predicted refrigerating capacity Hb is calculated, and a plurality of refrigerating units are automatically controlled through the predicted refrigerating capacity Hb. The control system applies the automatic control method. According to the method, the weekly coefficient table and the variable temperature coefficient are constructed, so that a model architecture of a computational formula for predicting the refrigerating capacity is obtained, and the refrigerating units are controlled through the
