The present invention relates to refrigerated trucks, more particularly to a refrigerated truck with side doors, including a refrigerated compartment, a chiller, a partition plate, glass plates, top plates, rotating shafts, side doors, support plates, air curtains, floors, base plates, slots, recessed handles, rails, moveable windows, moving handles and grooves. In the refrigerated truck with side doors of the present invention, doors are arranged on both sides of the refrigerated compartment, and the air curtains are used, which effectively reduces the amount of cold air loss and hot air intrusion, thereby reducing energy consumption of the chiller. Moreover, the support plates are configured to play an auxiliary role in both bearing load and keeping the balance. The present invention makes a contribution to energy saving of the refrigerated truck.

A vehicle comprising: a passenger compartment; a nose region forwards of the passenger compartment, the nose region having a top surface and a front; and a duct running from an inlet to an outlet to permit air flowing into the inlet to be channeled to the outlet, the inlet being positioned at the front of the nose region below the top surface and the outlet being positioned on the top surface of the nose region behind the inlet, the outlet being oriented so that air flowing through the outlet is directed in an upwards direction, the upwards airflow causing disruption to a rearward airflow moving towards the passenger compartment.

Provided herein is a system and method that detects an airborne object and determines a driving action based on the airborne object. The system comprises one or more sensors; one or more processors; a memory storing instructions that, when executed by the one or more processors, causes the system to perform detecting an airborne object within a detection radius of a vehicle. In response to detecting the airborne object, the system performs tracking the airborne object to obtain 3-D coordinate information of the airborne object at distinct times, determining a probability that the airborne object will collide with the one or more sensors based on the 3-D coordinate information, determining whether to take an action of the vehicle based on the determined probability, the action being one of actuating a shield to block the airborne object or activating an air curtain; and performing the action in response to determining to take the action.

A refrigeration unit for transportation, a door curtain thereof and a refrigeration vehicle. The door curtain includes: a curtain body; and a track, wherein the curtain body is movably mounted on the track, and the track has a main section for guiding the curtain body to move into a door area so as to be thermally insulated from the outside, and an extension section for guiding the curtain body to move out of the door area. The door curtain is a movable door curtain that is movable relative to the door.
