Abstract: An environmental control unit for use with a transport container is disclosed. The environmental control unit includes a thermoelectric device, a fan configured to blow air across the thermoelectric device, a cooling module, a controller in electronic communication with the thermoelectric device and the fan, and a communication module in electronic communication with the controller. The communication module is configured to transmit parameters of the environmental control unit to a computing device through wireless communication. The controller is also configured to determine a present location of the transport container, determine a destination of the transport container, evaluate an internal temperature of the transport container, and control an on or off condition of the thermoelectric device based on the present location, the destination, and the internal temperature of the transport container.

Abstract: A refrigerator includes a cold air supply device configured to generate an air curtain and disposed on an upper surface of the refrigerator. The cold air supply device includes a shielding module configured to selectively cover or open an air curtain hole supplying air to form the air curtain based on a door of the refrigerator being closed or opened.
