Problems solved by technology

[0006] Also, stationary systems do not allow operation in a tilted orientation, i.e., they are not portable
Conversely, this inclination leads to failure or damage to stationary systems
[0007] Therefore, there is a lack of transportable cooling units for the reliable transport of highly temperature-sensitive cargo while maintaining a desired cooling temperature greater than 70 K below ambient under changing environmental conditions

Embodiment Construction

[0044] figure 1 A portable cooling unit 1 according to the invention is shown, characterized by having two handles 2 ( figure 1 Only one of them is visible, see figure 2 ). The cooling unit 1 is divided into an insulated cooling chamber 6, in which highly temperature-sensitive goods are stored during transport, and a separate machinery chamber 7, which accommodates a multi-stage cascade refrigeration system. The cooling chamber 6 is closed off from the ambient air by a door 8 .

[0045] The multi-stage refrigeration system may be implemented as a two-stage cascade refrigeration system including two vapor compression refrigeration systems respectively forming a high temperature refrigeration cycle and a low temperature refrigeration cycle. Each of these refrigeration cycles includes such as figure 2 Compressor of the design shown.

[0046] exist figure 2 , the compressor is shown comprising a compressor housing 9 and a motor compression unit 3 elastically suspended on ...

Abstract

A portable cooling unit for transporting temperature-sensitive goods while maintaining a desired cooling temperature, comprising a multi-stage cascade refrigeration system adapted to operate during transportation of the portable cooling unit and adapted to be cooled to and maintained at a temperature more than 70 K lower than ambient temperature, a suspension system adapted and arranged to act as an elastic support of the multi-stage cascade refrigeration system and / or a component of the multi-stage cascade refrigeration system, a motion defining system adapted and arranged to limit motion of the multi-stage cascade refrigeration system and / or components of the multi-stage cascade refrigeration system, an impact protection system adapted and arranged to buffer collisions between the multi-stage cascade refrigeration system and other components of the portable cooling unit and / or between components of the multi-stage cascade refrigeration system, a lubrication system that facilitates lubrication of components of the multi-stage cascade refrigeration system for an inclination that deviates from a horizontal orientation of the portable cooling unit by at least 10 DEG, and a monitoring system adapted to generate an alert signal in the event of a failure of the portable cooling unit.

Description

technical field [0001] The present invention relates to a portable cooling unit for transporting temperature sensitive cargo while maintaining a desired cooling temperature. Background technique [0002] Portable cooling units are generally known. However, such cooling units, which work passively with dry ice or liquid nitrogen, cannot be used for highly temperature-sensitive cargo because they are unreliable over long periods of time and consume a limited supply of cooling medium. [0003] Furthermore, portable cooling units based on the Stirling cooling system are also not suitable for highly temperature sensitive cargo, as their relatively low cooling capacity prevents rapid restoration of the desired or required cooling temperature, eg after a door is opened. [0004] Typically, such portable cooling units cannot cool to and maintain temperatures 60-70K below ambient temperature, making them unsuitable for transporting highly temperature-sensitive cargo such as vaccines...
