The invention provides a control method and system of a refrigerating device and a computer readable storage medium. When the condition that a container exists in a distributor is detected, the refrigerating device selectively enters a water-taking mode or an ice-taking mode within a first preset time during timekeeping according to the different states of a sensor in the refrigerating device; after the refrigerating device enters into the water-taking mode, water directly flows from a water outlet of the refrigerating device; and after the refrigerating device enters into the ice-taking mode, ice directly flows from an ice outlet of the refrigerating device. Any operating button does not need to be touched by a user, so that the refrigerating device directly enters the whole water-taking mode or the whole ice-taking mode or exists in an automatic mode, a manual button is avoided from being arranged, the manual operating steps of the user are reduced, and operating experience of the user is promoted instead.
