The invention belongs to the technical field of vending machines and provides a vending machine refrigeration module, including a compressor, an evaporator, a condenser controller and a temperature sensor. The temperature sensor feeds back a detected temperature value to the controller. The detected temperature value is compared with a set temperature value to automatically adjust the motor speed of the compressor, the fan speed of the evaporator, and the fan speed of the condenser. The refrigeration module provided by the invention can automatically adjust the rotation speed of the compressor motor, the evaporator fan and the condenser fan according to the temperature detected by the temperature sensor, thereby avoiding full speed operation and reducing energy consumption and avoiding energy waste, improving energy efficiency.
