Abstract: A refrigerated compartment and refrigerated vehicle with dynamic control of a temperature field, including a compartment body. A refrigeration mechanism is fixed on a compartment body side wall and injects cold air into the compartment body. Steering mechanisms are fixed on the top wall of the compartment body, and each is connected with a fan. The fan accelerates the flowing cold air and the steering mechanism drives the fan to rotate and the change the cold air flow direction. Temperature sensors are equipped with the compartment body side walls and can detect the temperature. The temperature sensors are connected to a control mechanism arranged outside the compartment body and transmit detected information thereto. The control mechanism is connected to the steering mechanism, fan, and refrigeration mechanism through the speed regulator. The control mechanism controls the refrigeration mechanism working power and the operation of the steering mechanism and the fan.

Abstract: This invention provides a flow through type ultraviolet LED disinfecting apparatus, and a top cover and an outer cylindrical body are connected by a thread; a transparent inner cup body has a water holding tank inside for containing water, and there is a water pipe at the top of cover; a depth of the inlet water pipe reaching into the water holding tank has greater efficient than tank without pipe; a pipe mouth at one end of the inlet water pipe reaching into the water holding tank corresponds to a LED disinfecting light; the outer cylindrical body is tube-shaped, a side wall body and a bottom plate; the side wall body is sleeved outside the transparent inner cup body; a bottom of the transparent inner cup body contacts with the bottom plate of the inner cylindrical body; he circuit board with LED disinfecting LED is fixed at the bottom plate.
