Abstract

The application discloses a refrigeration equipment, and belongs to the refrigeration equipment field. The refrigeration equipment comprises a main fan, a main air duct, an auxiliary air duct, an auxiliary fan, and an infrared sensor. The main fan is used for driving air flow in the refrigeration equipment. The main air duct is arranged between the main fan and a main air outlet of the refrigeration equipment. The auxiliary air duct is communicated between the main air duct and an auxiliary air outlet. The auxiliary fan is used for driving air flow of the main air duct to the auxiliary air outlet. The infrared sensor is used for acquiring sensor data around the refrigeration equipment in the case that the refrigeration equipment is turned on. The sensor data comprises at least one of position information of a user from the refrigeration equipment and thermal sensation information of the user. A controller is used for controlling the rotating speed of the main fan, controlling a target number of centrifugal fans to be turned on, and controlling a target position of the centrifugal fan to be turned on based on the sensor data. The refrigeration equipment can realize detection and feedback control based on the real temperature and cold feeling of the user, and realize automatic adjustment control with the personalized demand of the actual thermal sensation of the user as the target.
