Abstract
Official abstract text for this publication.
A refrigerated storage container is provided and includes a container housing defining an interior, an air conditioner operable to maintain control of temperatures within the interior and a local controller configured to cycle the air conditioner on and off within a time window based on waste heat ingestion from neighboring refrigerated storage containers.
First claim
Opening claim text (preview).
What is claimed is: 1. A refrigerated storage container disposed proximate to neighboring refrigerated storage containers in a ship or a yard, the refrigerated storage container comprising: a container housing defining an interior; an air conditioner comprising a condenser supportively disposed on an end wall of the container housing, the air conditioner being operable to maintain control of temperatures within the interior; a local controller; and a sensor operably disposed to sense a temperature of the interior and to transmit data reflective of the temperature to the local controller, the local controller being configured to cycle the air conditioner on and off within a time window, which is predefined in accordance with temperatures within the interior and allowable temperature variability around a set-point, based on waste heat ingestion from the neighboring refrigerated storage containers and derives a value of the waste heat ingestion from a difference between periodically measured ambient and condenser inlet air temperatures. 2. A refrigerated storage container disposed proximate to neighboring refrigerated storage containers in a ship or a yard, the refrigerated storage container comprising: a container housing defining an interior; an air conditioner comprising a condenser supportively disposed on an end wall of the container housing, the air conditioner being operable to maintain control of temperatures within the interior; a local controller; and a sensor operably disposed to sense a temperature of the interior and to transmit data reflective of the temperature to the local controller, the local controller being configured to cycle the air conditioner on and off within a time window, which is predefined in accordance with temperatures within the interior and allowable temperature variability around a set-point, based on waste heat ingestion from the neighboring refrigerated storage containers wherein the local controller is configured to: limit a number of cycles within the time window, implement an override command to force the air conditioner to cycle in an event a temperature within the interior reaches a limit, and override a cycling command issued by a supervisory controller.
