The main controller is capable of calculating a dew point value of the air in the testing chamber according to a temperature value and a humidity value of the interior the testing chamber acquired by the temperature and humidity sensor, and if the dew point value of the air is greater than a pre-determined threshold, the main controller controls the cooling plate control unit to reduce the number of operating electronic cooling plates or output powers of the electronic cooling plates, wherein the pre-determined threshold is a temperature T1° C. of the electronic cooing plate or a temperature T1+n° C. of the electronic cooling plate acquired by the temperature sensor, and n≤is less than or equal to 10. The present disclosure achieves real-time control of operation states of the electronic cooling plates, thereby realizing redundant control of the cooling plates, and preventing the cooling plates from causing condensation in the chamber body, so as to achieve continuous operation when a failure occurs.

Disclosed is a power control system for a container vessel. The power control system has a power interface for supplying energy to at least one reefer container transportable by the container vessel. The power control system also has a controller configured to obtain load data representative of a load on a generator of the container vessel, and target load range data representative of a target load range for the generator. The power control system is configured to control the load such that the load falls within the target load range by the controller increasing energy supplied to the power interface for storage at the at least one reefer container, when the load is below the target load range.

In accordance with the principals of the present invention, an ice machine, tray, and process for producing high-quality, substantially clear ice is provided. A heat exchanger in the ice machine removes energy from liquid, cooling the liquid from room temperature to freezing temperature, then overcomes the heat of fusion to form ice. The tray containing a liquid is received in a freezing/mixing chamber. The tray includes an energy transfer surface in thermal contact with the heat exchanger to define a liquid/ice boundary layer. The tray further includes at least one freezing cavity having geometry defining surfaces to form the geometry of the ice. An egress area is defined in the tray above the geometry defining surfaces. A mixing mechanism is provided in operative communication with the liquid to create a velocity profile at the liquid/ice boundary layer to create a directional freezing process starting from the energy transfer surface of the tray in thermal contact with the heat exchanger and growing through the freezing cavity up to the egress area. The velocity profile at liquid/ice boundary enables impurities to be washed away during the freezing process, deterring impurities from getting entrapped in the ice. Impurities in the liquid are thereby washed away and concentrate in a pool away from the ice, ultimately in the egress area of the tray to be purged. In addition, in embodiments sensors can be provided to provide various functions selected from the group consisting of, for example, determining ice creation status, determining freezing height, varying ice creation, determining tray presence, detecting freezing/mixing chamber door position, determining liquid level, and combinations thereof.

Here, the temperature controller inputs the external temperature information and the expected arrival time information to the neural network model to estimate a temperature change of the item and sets in advance a target cooling temperature of the cold-storage chamber based on an estimated temperature change of the item.
