The invention provides a control method and system of refrigerating equipment and a computer readable storage medium. When a master control board receives an instruction sent by any wire controller for requesting downloading previously stored user parameters, the user parameters are sent to the any wire controller sending the request, so that when the wire controller is changed by a user, the user parameters do not need to be set again, the complicated process of setting the parameters is avoided, and the experience of the user is improved. Secondarily, after the master control board stores the user parameters in a master control board storage, a plurality of wire controllers can directly download the user parameters from the master control board by using the master control board as a medium. When the user parameters are the same parameter, the process of setting the wire controllers one by one can be avoided, the operation experience of the user is improved, and the market competitiveness of the product is improved.
