The utility model relates to an environment adjusting technology suitable for an intelligent control cabinet and especially relates to an environment adjusting system for the intelligent control cabinet. The structural key points of the environment adjusting system are that the system comprises a central air conditioner; two air conditioning internal units are arranged in each intelligent control cabinet, namely a main internal unit and a spare internal unit; and a cold supplying pipeline of the central air conditioner is respectively connected to the air conditioning internal units of each intelligent control cabinet. In the environment adjusting system of the intelligent control cabinet, the central air-conditioner acts as a main operation system and a main and a spare air conditioning internal units are arranged in each intelligent control cabinet, so operation maintenance cost can be greatly reduced and cold can be reliably conducted; and safe operation of equipment in the cabinet cannot be affected, so stable operation of the intelligent control cabinet can be substantially guaranteed.
