A dynamic temperature regulating device is for use in association with a temperature-controlled container. The dynamic temperature regulating device includes at least one heat source, at least one heat sink, a heat transfer medium and a control system. At least one of the heat source and the heat sink is a PCM (phase change material). The heat transfer medium is in thermal communication with and operably connected to the at least one heat source and the at least one heat sink. The control system is for controlling the selective thermal communication with the at least one heat source and with the at least one heat sink to regulate the temperature of the temperature-controlled container. A detachable PCM contained volumes includes a sealed housing, a phase change material and a heat transfer medium and functions as a PCM thermal energy storage volume.

A phase change material includes a salt-water solution having a first salt, a second salt and water; a gelling agent; a thermal conductivity enhancer; and a nucleation agent. The phase change material is suitable for use as a cold storage material, in particular, for maintaining an environment at a temperature of from −15 to −40° C. The phase change material may be used in a cold storage pack.

A portable thermal insulated apparatus for cooling or heating items stored therein. The thermal insulated apparatus includes a container having a lid that removably secures to an open first end thereof and a reservoir unit that removably secures to an open second end. The container includes an inner tube and an outer tube forming an insulated double-wall sealed at both ends in which the lid and reservoir unit can be connected thereto. The reservoir unit removably receives a thermal unit that provides cooling or heating to the contents of the container when affixed thereto. The thermal unit is separable from the reservoir unit, such that the thermal units are interchangeable as needed. In some embodiments, the thermal unit is directly securable to the lid and the second end of the container is permanently sealed.

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.
