The utility model discloses a low temperature rectisol ammonia system refrigerating system. The low temperature rectisol ammonia system refrigerating system is mainly used at low temperature rectisol working section deacidification process of coal chemical industries. An ammonia cooler 1 is arranged on a pipe position from a first section to a second section of a tower 9, an ammonia cooler 2 is arranged on a position from a third section to a fourth section of the tower 9, an ammonia cooler 3 is arranged between a first section of a tower 10 and a first section of a tower 11, a heat exchanger 7 and a heat exchanger 8 are arranged between a tower 11 and a tower 12, and an ammonia cooler 4 is arranged between the heat exchanger 7 and the heat exchanger 8. By adding the ammonia coolers, methanol flows out of the heat exchanger 8, enters the ammonia cooler 4 first, then enters the heat exchanger 7, and therefore system heat is balanced and reduced, temperature of the methanol entering the tower 9 is reduced and p
