A moisture detector includes a sensor chip and a moisture determining unit. The sensor chip includes a humidity detector having a detection surface on which to measure humidity, and also includes a heater heating the detection surface, and the moisture determining unit is configured to, after causing the heater to start heating, determine whether moisture is present on the detection surface based on a difference in changes in the humidity measured by the humidity detector.

A cooler device having a body and lid that can be secured shut and locked against the cooler body with a combination lock, keypad lock, key operated lock or electronic lock installed on the body of the cooler or lid of the cooler and that has retractable wheels that retract into the body when the cooler is stationary and released by a spring mechanism to extend the wheels for rolling the cooler.

A method of shutting down a refrigeration system including: initiating a shutdown process of the refrigeration system; closing a first valve within a refrigerant circuit of the refrigeration system; operating a compressor within the refrigerant circuit; detecting a suction pressure within the refrigerant circuit; closing a second valve within the refrigerant circuit of the refrigeration system when the suction pressure is below a threshold suction pressure; and stopping operation of the compressor.

A releasable locking mechanism for a refrigerated unit. A latch plate is movable between a position that can be engaged by a deadbolt and a position clear of the deadbolt. The latch plate is moved by a door release accessible from an interior of the refrigerated unit. When the door release is activated, a pin blocks movement of the latch plate so that the refrigerated unit remains unlocked until the pin is reset.

The present invention (1) relates to a folding and portable refrigerated cabinet comprising a locked-compartments structure, made up of the reversible combination of three elements:—a plinth,—a folding exterior structure positioned on the plinth,—a folding interior structure with compartments set into the exterior structure, the plinth containing a refrigeration unit, the folding exterior structure comprising a hermetically sealed facade closed by a refrigeration door, the other sides being covered with a removable isothermal insulation means (4), the folding interior structure with compartments being made up of at least one module comprising walls delimiting at least one closed volume inside the folding exterior structure, said closed volume constituting a compartment (24, 25, 26, 27) provided with a mobile partition allowing the volume of the compartment to be varied as two sub-compartments (24′/24″, 25′/25″, 26′/26″, 27′/27″), each of said compartments and sub-compartments being closed by a door comprising a secured-access means.

A system for monitoring and reporting internal refrigeration unit temperatures includes a temperature measuring device for placement within the refrigeration unit. The temperature measuring device has a first temperature sensors situated in a liquid or solid mass (e.g. glycol or glass beads) for measuring an average temperature within the refrigeration unit and/or has a second temperature sensors exposed to ambient air within the refrigeration unit for measuring an instantaneous temperature within the refrigeration unit. A circuit periodically transmits the average temperature and/or the instantaneous temperature from the temperature measuring device to a server where the average temperature and the instantaneous temperature are analyzed to determine and/or predict a fault with the refrigeration unit. Upon determination and/or prediction of the fault, an alert is sent to at least one staff member indicating the refrigeration unit and fault.

A refrigerated transport system comprises a body enclosing a refrigerated compartment. A refrigeration system (29) comprises first and second vapor compression loops each having: a refrigerant charge; a compressor (36A,B) for driving the refrigerant of the refrigerant charge; a first heat exchanger (38A,B) positioned to reject heat to an external environment in a cooling mode; and a second heat exchanger (42A,B) positioned to absorb heat from the refrigerated compartment in the cooling mode.

Provided are a refrigerator and a cloud server that diagnose a cause of an abnormal state. According to an embodiment of the present disclosure, an abnormal state diagnosis unit included in the refrigerator or the cloud server generates information on the abnormal state of the refrigerator based on similarity between stored first group of information and a normal pattern, and a cause diagnosis unit generates, when the abnormal state diagnosis determines that a state of the refrigerator is an abnormal stte, information on cause of the abnormal state based on similarity between stored second group of information and a defect pattern.

A food safety system for food items in cooled environments includes a temperature sensor unit having a temperature sensor, a power supply and a data transmission element. The temperature sensor unit is positioned in a cooler, wherein the cooler has a plurality of predefined food item positions. A control center unit having a computer processor and a memory is adapted to execute a deterministic mode function to predict the core temperature change of such a food item on a predefined food item position in said cooler. The deterministic mode function depends on heat transfer parameters related to the predefined food item position of the cooler used, food specific coefficients related to the kind of food item taken from a group of food types, the environment temperature measured by the temperature sensor, and the predicted current core temperature of the food item.

A refrigerator includes: a cabinet; an upper door; a lower door that is a drawer type door; a draw-out rail that connects the lower door to a storage space in the cabinet and that guides insertion and withdrawal of the lower door in a front-rear direction; an elevation assembly that is located in the lower door, that elevates an object stored in the lower door in a state in which the lower door is withdrawn, and that elevates the object relative to the lower door; and a door restriction device configured to selectively restrict an opening movement of the upper door based on whether the lower door is opened or closed. The door restriction device is configured to restrict the opening movement of the upper door based on the lower door being opened, and to allow the opening movement of the upper door based on the lower door being closed.
