The invention discloses an automatic control method for steam condensate recovery, and belongs to the technical field of chemical engineering automatic control. After steam is cooled by a refrigerant, water molecules are condensed into water drops, the water drops converge and flow away, air is directly discharged, and the low temperature of the part of gas is not utilized and then is discharged; according to the invention, air with moisture removed after steam condensation is conveyed into a cooling tank in a timed and quantitative manner through a pneumatic control valve on an exchanger, so that a part of steam forms a condensate, and the condensate is condensed again after the heat exchange, so that the heat exchange efficiency is improved, and the heat exchange efficiency is improved. Therefore, the steam is cooled in advance, the cooling efficiency is improved, the single discharge amount ratio of the refrigerant is reduced, the use amount of the refrigerant is reduced, the workload of cooling the refrig
