Method for adjusting environmental control equipment and method for establishing comparison database of environmental control equipment

The invention discloses a method for adjusting environment control equipment, which comprises a comparison database establishing step, a comparison step and an execution step, in the comparison database establishing step, a comparison database is pre-established, and a plurality of environment control modes corresponding to the environment control equipment are stored in the comparison database in a plurality of reference outdoor environment parameter ranges; each environment control mode can enable a closed space to maintain a required internal environment parameter range, and the comparison step is that the processor obtains a to-be-adapted outdoor environment parameter and compares the to-be-adapted outdoor environment parameter with the reference outdoor environment parameter range; the execution step is that the processor controls the environment control equipment to operate in the corresponding environment control mode according to the reference outdoor environment parameter range which is matched with
