Control device of refrigerating system and refrigerating device with same

The invention discloses a control device of a refrigerating system and a refrigerating device with the same. The control device comprises a power supply, a temperature magnetic control switch, a switching unit, a mechanical temperature controller and a controller, wherein one end of the temperature magnetic control switch is connected with one end of a compressor; the open and close of the metal contact point of the temperature magnetic control switch are controlled according to the changes of magnetic filed intensity caused by the changes of the environment temperature of the temperature magnetic control switch, and the other end of the compressor is connected with the power supply; the switching unit is provided with an input end, a first output end and a second output end; the input end is connected with the power supply, and the first output end is connected with the other end of the temperature magnetic control switch; one end of the mechanical temperature controller is connected with one end of the compressor, and the other end of the mechanical temperature controller is connected with the second output end of the switching unit; and the controller controls the switching unit to be switched between the first output end and the second output end. The control device provided by the invention can be converted between automatic regulation and control and manual regulation and control of temperature through the switching unit, thus requirements of different users are met; and the control device is simple in structure and has low cost.
