Abstract:
A device and method for cooling an air inside a cargo space by freezing an eutectic solution of an eutectic device. The eutectic device is installed inside a cargo space of a refrigerated transport unit. A cryogen is provided to a cryogen circuit of the eutectic device that is connected to a transport unit. Then the cryogen is circulated through the cryogen circuit, transferring heat from the eutectic medium to the cryogen. This transfer of heat freezes the eutectic medium. The frozen eutectic medium is used to cool a cargo space of a container of the transport unit.
Abstract:
A heat exchanger includes a first housing disposed in a first atmosphere and having an upstream end, a downstream end and an internal space for a cryogenic substance; and a heat plate assembly mounted to the first housing and being exposed to the first atmosphere for providing heat transfer at an interface of the first atmosphere and the heat plate assembly.
Abstract:
A cooling system (2) for an interior space of a vehicle comprises a main cooling system (4) coupled with an air inlet (6) for receiving air (10) and coupled with the interior space (12, 14, 16, 18, 20) for providing cooled air to the interior space (12, 14, 16, 18, 20), at least one air (8, 22, 24, 26) duct arranged between the air inlet (6) and the interior space (12, 14, 16, 18, 20), a reservoir (30) for liquid nitrogen having a nitrogen outlet (34) and a valve (36) arranged between the outlet (34) and an injection port (38) of the at least one air duct (8, 22, 24, 26). The reservoir (30) is couplable with the injection port (38) of the at least one air duct (8, 22, 24, 26) via the valve (36) on demand for evaporating nitrogen in the at least one air duct (8, 22, 24, 26). With the injection of liquid nitrogen the main cooling system (4) is supported in case it is not able to provide a sufficient cooling power.

Abstract:
A method for controlling a transport refrigeration system (TRS) for refrigeration of a transport unit is disclosed. The TRS includes a TRS controller connected to the TRS for operating the TRS. The TRS includes an eutectic device including an eutectic medium, a transport refrigeration unit (TRU) having a refrigerant circuit for directing a refrigerant through the TRU and capable of directing the refrigerant to the eutectic device for cooling the eutectic medium. The TRS includes a cooling fluid circuit in thermal contact with the eutectic medium, wherein the cooling fluid circuit directs a cooling fluid to be in thermal contact with the eutectic medium.
Abstract:
An inter-region thermal complementary (combination of heat supply with exhaust heat) system capable of complementing a heat by forming an endless loop so as to complement each other the heat produced in the regions such as plants and areas, performing a heat transfer without performing the forced circulation of water by a pump in the endless loop independently of the circumferential diameter of an annular endless water channel, i.e., the areas of the regions to be supplied with heat, wherein an endless multiplex helical loop sealed with liquid or slurry fluid body forms the temperature zones different from each other for each loop without being forcibly circulated by the pump, a distributed cryogenic source and a thermal source are thermally connected to the multiplex helical loop so that the heat can be taken in and discharged between the different loops, whereby a fluid body force-fed energy can be dissipated, a running cost can be reduced, network refrigerators and heat source machines can be distributedly used and networked, and an energy supply system can be centrally controlled through the multiplex helical loop.
