A method for controlling a refrigerator according to an embodiment of the present invention is characterized by comprising: a step for determining whether a defrosting period (POD) for defrosting a freezing chamber and a deep freezing chamber has elapsed; a step for, when it is determined that the defrosting period has elapsed, performing a deep cooling operation for bringing at least one among the temperature of the deep freezing chamber and temperature of the freezing chamber down to a temperature lower than a control temperature; and a step for defrosting the deep freezing chamber when the deep cooling operation is terminated, wherein, when the defrosting of the deep freezing chamber is started, a freezing chamber valve is closed to block cold air flow to the heat sink, the defrosting of the deep freezing chamber includes cold sink defrosting and heat sink defrosting performed after the cold sink defrosting is completed, and while the heat sink defrosting is being performed, a deep freezing chamber fan is driven to remove vapor generated during the cold sink defrosting.

A method for controlling a refrigerator according to an embodiment of the present invention is characterized by comprising: a step for determining whether a deep-freezing chamber mode is ON; and a step for determining whether a deep-freezing chamber load response operation input condition is satisfied, wherein when a cold chamber is determined to be operating at the time the deep-freezing chamber load response operation input condition is satisfied, the cold chamber operation is terminated and a deep-freezing chamber load response operation is performed.

An apparatus comprises a chamber and two pumps coupled to opposing sides of the chamber. The chamber is configured to receive a medium and includes a first cryogenically cooled structure having a first surface and an opposing second surface and a second cryogenically cooled structure having a first surface and an opposing second surface. The first surface of the first cryogenically cooled structure faces the first surface of the second cryogenically cooled structure forming a gap. The gap is configured to receive the medium. The chamber also includes a gas inlet.

Particulate material is cooled by passing into the material a coolant stream of liquid nitrogen having a gaseous product around at least a portion of the liquid nitrogen, wherein the coolant stream is formed outside the particulate material in a nozzle body from which the coolant stream is passed into the particulate material.

A system for controlling a temperature a within an interior volume of a cargo trailer adapted to transport perishable goods is described herein. The system includes a fluid distribution assembly and a monitoring system. The fluid distribution assembly is configured to selectively channel a flow of cryogenic cooling fluid into the cargo trailer interior volume to facilitate adjusting a temperature within the interior volume. The monitoring system includes at least one sensor for sensing an environmental parameter of the cargo trailer, and a controller coupled to the sensor and to the fluid distribution assembly. The controller is configured to receive a monitoring signal indicative of the sensed environmental parameter, determine an environmental condition of the cargo trailer as a function of the environmental parameter, and provide a notification signal if the determined environmental condition is different than a predefined environmental condition.

Selection of an optimum container that can ensure the quality of an article from a plurality of containers according to the type of the article, to calculate a rental unit price of one container to be commonly used at a time of delivering the article and at a time of storing the article at a delivery destination, and to calculate a rental fee of the container. A received-order management server calculates delivery date data and collection date data based on an article code and use date data received from a user terminal on a user side, and selects a container of a type corresponding to the article from plural kinds of containers based on the article code. The server then calculates a billing amount by multiplying a unit price by a rental period calculated based on a delivery completion notification and a collection completion notification received from a delivery unit.

The present disclosure provides cryogenic storage systems and methods of using the cryogenic storage systems. A cryogenic storage system of the present disclosure may comprise a cryogenic tank with an inner door and an outer door, and a robot apparatus located adjacent to the cryogenic tank. The cryogenic tank may store multiple racks such that at most a single rack is removable through the inner door or the outer door. The cryogenic tank may store the multiple racks in multiple groups of racks comprising a first group of racks located at a first radial distance and a second group of racks located at a second radial distance that is greater than the first radial distance. The robot apparatus may selectively open and close the inner or outer doors, and insert or withdraw the single rack into or out of the cryogenic tank through the inner door or the outer door.

A cryostat includes a room temperature vessel, a low temperature vessel, and a refrigeration mechanism. The room temperature vessel includes a room temperature tank, an outer neck tube and a sealing head. The low temperature vessel includes a low temperature tank, an inner neck tube and a liquefaction chamber. The liquefaction chamber corresponds to the first opening and passes through the first opening. The refrigeration mechanism includes a device panel and a refrigeration device. The device panel is disposed on the sealing head. The refrigeration device includes a body and a cold finger. The body is disposed at the device panel. The cold finger is connected with the body and extends into the liquefaction chamber.

A cryogenic refrigerator includes a pulse tube cryocooler including a pulse tube, and a pulse tube cryocooler rotating mechanism that rotatably supports the pulse tube cryocooler allowing it to be changed from a cooling posture to a heating posture. When the pulse tube cryocooler is in the cooling posture, an inclination angle formed between a vertical line and a center axis of the pulse tube is a first angle, and when the pulse tube cryocooler is in the heating posture, the inclination angle is a second angle. In a case where the inclination angle formed when a cold end of the pulse tube faces vertically downward is defined as zero degrees and the inclination angle formed when the cold end of the pulse tube faces vertically upward is defined as 180 degrees, the second angle is larger than the first angle.
