Railcar backup cooling system
A railcar backup cooling system may be added to an existing railcar (e.g., a boxcar) to provide supplemental or backup cooling to the railcar in the event that an HVAC failure or other circumstance occurs, which causes the interior temperature of the railcar to rise. The system includes a container of liquid or compressed gas mounted on the railcar, a valve controlling the flow of the liquid or gas from the container, and a controller configured to open the valve when the HVAC system fails or is otherwise unable to maintain the railcar at the desired temperature. When the valve is opened, the liquid and/or gas stored in the container may exit, expanding into a cool gas and thereby acting to cool the railcar environment.
Hydraulically controlled cryopreservation device
This cryogenic preservation or vitrification device (1) comprises: an accumulator (2) including a first volume of pressurised hydraulic oil; a control system controlling a valve (20) capable of releasing a second volume of hydraulic oil from the accumulator toward a cylinder (55) by means of a pipe (4); a cylinder (55) including a piston (6) configured to be driven by the second volume of hydraulic oil and to displace a first volume of cryogenic fluid to a cryogenic vessel (7) intended to receive a sample (8) to be cryogenically preserved.
Method for freezing a substance
An instant freezer apparatus able to freeze consumable fluids and food having a freezing point lower than water is disclosed. The method of the present invention is directed to freezing of a substance such as to instantly freeze consumable fluids and food without altering their chemical compositions. The instant freezer apparatus generally comprises a main frame and a removable freezing module. The apparatus may further comprise a freezing fluid injection system such as a liquid carbon dioxide tank or a liquid nitrogen tank fluidly connected to the main frame. At least two freezing cells comprising the fluid to be frozen may be included, the freezing cells being independently removable from the freezing module and other freezing cells. A semi-flexible mat for receiving and supporting varying shapes of freezing cells may be included.
EVAPORATIVE COOLING SYSTEMS AND METHODS OF CONTROLLING PRODUCT TEMPERATURES DURING DELIVERY
In some embodiments, systems and methods are provided that limit the change in temperature and/or control a temperature of a product during delivery. Some embodiments provide systems to limit temperature changes, comprising: an evaporative product cooling system comprising: a product cavity that supports a product while the product is transported to a delivery location, wherein the product cooling system comprises an interior wall defining the product cavity, an exterior wall, an evaporative cavity between the interior and exterior walls, a coolant dispensing system, at least one evaporative opening, and a temperature sensor; and a temperature control circuit configured to receive temperature data from the temperature sensor while the product is in transit, determine that a temperature of the product is greater than a transport temperature threshold, and autonomously activate the coolant dispensing system to release evaporative coolant into the evaporative cavity while the product is transported.
Method for regulating the temperature of the storage chamber for products of an indirect injection vehicle transporting heat-sensitive products
The invention relates to a method for transporting heat-sensitive products in a refrigerated lorry of the indirect injection type, wherein the temperature T.sub.int inside the storage chamber is regulated by varying the pinch of the exchanger (Pinch=T.sub.int−TFluid outflow) according to the position of the internal temperature T.sub.int in relation to a temperature set value.
Container for cryopreserved samples
Containers (100) for cryopreserved biological samples (102) may include an insulated housing including a cavity (108) for containing at least one cryopreserved biological sample; and a sealed reservoir (106) at least partly surrounding the cavity, the sealed reservoir including liquified gas (120) such as liquified air, the gas being kept largely liquified by a heat transfer engine (112) such as a Stirling cryocooler. A valve (114) may be provided to function as both a pressure relief valve and an inlet valve. The inlet valve may be coupled to a sensor (122) for sensing a volume of liquified gas within the sealed reservoir. The container may further include a heat exchanger (116) coupled to the heat engine and extending into the sealed reservoir.
Portable cooling device
A system for a portable cooling device is disclosed herein. The portable cooling device comprises a housing and a door with a handle coupled to the housing for providing access to the interior of the housing. The door and housing are insulated. At least one fan is provided in the interior of housing. In an embodiment, a plurality of fans are configured on each surface defining the interior of the housing. A cooling medium source is in fluid communication with the housing. The cooling medium source is configured to release a cooling medium in the interior of the housing for cooling an edible item or beverage placed in the interior of the housing. The portable cooling device can be powered through solar means or through traditional electrical means. The power is necessary to operate the fans and the cooling medium source.
Method for retrieving storage racks from a tank freezer using a retrieval crane, and related combinations
A method for retrieving storage racks in a tank freezer includes positioning a retrieval crane adjacent to the tank freezer such that a base of the retrieval crane is positionable underneath a bottom wall of a tank body. The retrieval crane includes a boom extending upwardly and laterally outwardly over the base so that a retention hook at a free end of a cable associated with the boom may be extended or retracted relative to the tank freezer. More specifically, the cable may be moved to extend the hook through the opening of the tank freezer into a storage space, and then retract the hook to lift and then hold a selected storage rack in a hoisted position. The method avoids the use of manual hoisting of storage racks, and the retrieval crane may be used with any of a plurality of similar tank freezers located in a larger facility.
SELF-POWERED, LONG-TERM, LOW-TEMPERATURE, CONTROLLED SHIPPING UNIT
A shipping vessel includes a cryogenic tank secured to the shipping foundation; a payload bay to receive products therein; a tube connected to the cryogenic tank and thermally coupled to the payload bay; a housing secured to the shipping foundation, said housing covering the tube and the payload bay to thermally seal the payload bay from outside environment; a controller mounted on the housing and having a sensor to determine temperature in a closed-loop and maintaining a set point within a predetermined range; and an energy storage device coupled to the controller and electronics to provide power for a predetermined shipping period.
