A picnic cooler with a cooling mechanism based on the use of liquid nitrogen, that comprises four sides, bottom, cover, an internal compartment, an adapter. The internal compartment is integrated into one or more sides of the cooler and is made of a material that cools rapidly upon contact with the quick nitrogen. The internal compartment has one or more ventilation opening. The connector is designed to enable the attaching of an external canister of liquid nitrogen so as to enable introduction of liquid nitrogen from the canister into the internal compartment through the connector.

A refrigeration manager that can be used to monitor and control disparate refrigeration systems at a site, even when the refrigeration systems are manufactured by different vendors. The refrigeration manager provides common views for the disparate refrigeration systems, which may help a technician more easily monitor and control the various refrigeration systems at a site.

The invention provides a compact and self-sustained refrigeration system for medical uses, including in hospitals, in clinics and in home uses, including rescue and field emergency situations, independent of external power supply, based on small amounts of liquid carbon dioxide.

A self-cooling container for cooling a liquid includes a first portion with a first frangible seal that extends across and seals an evaporator unit containing a refrigerant and a second portion with a second frangible seal that extends across and seals a desiccant chamber containing a desiccant. The first portion rotates axially relative to the second portion. An actuator assembly is between the first portion and the second portion and includes: a cutter assembly, which is coupled to the first portion of the self-cooling container and includes a cutter coupled to a rotatable axle and a pinion gear coupled to the rotatable axle, and a drive gear assembly coupled to the second portion of the self-cooling container and including a ring gear supported by a housing. The pinion gear on the cutter assembly is mated to the ring gear of the drive gear assembly.

A portable temperature-controlled container for receiving and housing one or more handheld carriers, each handheld carrier configured to transfer samples to and from a temperature-controlled storage environment, the handheld carrier including a handle and a tray portion, the tray portion configured to be slid into a port of a rack or tower provided in the temperature-controlled storage environment in order to withdraw a sample located in the port, the portable temperature-controlled container including a housing having an opening forming an internal cavity configured to receive one or more handheld carriers, and a lid configured to substantially close the opening, where the housing includes a recess configured to receive the handle of the handheld carrier such that closing of the lid substantially seals the internal cavity when the one or more handheld carriers are placed in the housing.

Standalone and self-contained cooling systems using compressed liquid and/or gas CO.sub.2 containers positioned in an insulated or non-insulated vessel encompassing a container which is either vertically positioned in an upright or an upside-down position. The liquid and/or gas CO.sub.2 coolant is then released into a capillary system or flow metering system to allow the CO.sub.2 to enter a second body to where the CO.sub.2 coolant properties may be leveraged. The second body includes, by way of example, a plate, a cushion, a spot treatment pad for a person's muscle, or a cooler. The temperature is controlled by a metering CO.sub.2 releasing system encompassing an electronic control device which sends alerts when pre-defined thresholds are exceeded. The invention's metering CO.sub.2 releasing system may be triggered by an electronic or a thermostatic valve or may be triggered manually or by an electronic solenoid.

A system includes a heat exchanger mounted to the brackets and receiving cryogen, the heat exchanger having a vertical inlet coupled in parallel to a plurality of equal size horizontal tubes each traversing a width of the heat exchanger and further coupled in parallel to a vertical outlet pipe with an outlet diameter at least twice an inlet tube diameter; a temperature sensor; a thermostat that monitors the temperature sensor and maintains a predetermined temperature set point by communicating with a solenoid valve coupled to the heat exchanger; an exhaust line coupled to the outlet pipe that expels exhaust gas outside the enclosed facility; multiple fans attached to the heat exchanger; and a fail-safe oxygen sensor to protect a biological object in the enclosed facility.

Devices for cooling beverages in cooperation with a compressed gas cartridge. The devices include a housing, a head, a working fluid, and a release mechanism. The housing defines a chamber complementarily configured with the compressed gas cartridge to receive the compressed gas cartridge. The head couples to the housing and defines an interior void in fluid communication with the chamber. The working fluid is contained with the interior void of the head. The release mechanism is operably connected to the housing and configured to selectively release compressed gas from the compressed gas cartridge into the interior void of the head. The compressed gas cools the working fluid when the compressed gas is selectively released from the compressed gas cartridge and contacts the working fluid in the interior void. The head is configured to be placed in a beverage to cool the beverage.

A picnic cooler that includes a food compartment, a gas tank compartment, an off/on electric spigot, a first sealing rings with a first apertures a second sealing ring with a second aperture, and two cooling apparatuses. The cooling apparatus includes a twisting piping system and an upper metallic plate that serves as the bottom of the food compartment. The ratio between the diameter of the second aperture and the diameter of the first aperture is between 1.8 to 2.2 and the ratio between the inner surface area of the food compartment and the outer surface area of the first and second piping systems is between 9 to 17.
