Abstract
A cooler box with a temperature control function, the cooler box comprises a box body and a cryogenic medium container installed outside the cooler box for storing liquid carbon dioxide or other liquefied gas. The box body is equipped with a controller, a monitoring device, a controllable valve, and a chamber to reduce the speed of gas released and thus prevent sudden freezing and overcooling of temperature-sensitive cargo such as fresh food. The controllable valve is connected to the cryogenic medium container through a tube. The monitoring device measures the temperature inside the cooler box, and the controller controls the valve opening state and the duration time of maintaining the open state of the controllable valve according to the temperature measured by the monitoring device and the size of the cooler box. A temperature control method for the cooler box is also provided.
