Problems solved by technology

While undeniably able to bring the temperature back down very quickly, this consumes more energy and results in more cost than necessary
Other common devices for cold insulation systems such as curtains are not suitable in the case of CT refrigerated vehicles because they are not conducive to ventilation, which is dangerous

Embodiment Construction

[0039] FIG. 1 shows a side view of a refrigerated vehicle 2 according to the invention with a refrigeration module 10 mounted in the upper region on the front side 50 of the refrigerated vehicle 2 . The refrigeration module 10 includes an evaporator 1 and a heat exchanger 30 (see figure 2 ), supplying the liquefied gas from the insulated storage tank 5 to the evaporator 1 and the heat exchanger 30. The storage tank 5 has a thermally insulating jacket, preferably a vacuum jacket or even a foam jacket, and is fluidically connected to the refrigeration module 10 . The storage tank is installed in the lower region 12 of the refrigerated vehicle 2 .

[0040] figure 2 An evaporator 1 is shown, which is arranged outside the cold storage compartment 4, 9, the evaporator 1 forming part of a heat exchanger 30, in order to release the cold produced by evaporating the liquefied gas to the cold storage compartment 4, 9 In the cooling air 39 to be cooled down. Goods (not shown here) sto...

Abstract

The invention relates to a mobile refrigerated vehicle (2) comprising a refrigerated chamber housing (3) for at least one refrigerated chamber (4) contained therein, a tank (5) for liquefied gas, an evaporator (1) for the evaporation of the liquefied gas during the delivery of cold to the refrigerated chamber (4) and an exhaust pipe (6) for the evaporated gas, in conjunction with which the evaporator (1) is arranged outside the refrigerated chamber (4); and a method for ref rigerating a refrigerated chamber (4) of a mobile refrigerated vehicle (2). The invention is characterized in that dependable and efficient refrigeration of products can be achieved in conjunction with particularly high operational reliability and energy-saving.

Description

technical field [0001] The invention relates to a mobile refrigerated vehicle and a method for cooling a refrigerated compartment of the mobile refrigerated vehicle, said refrigerated vehicle comprising a refrigerated compartment housing for at least one refrigerated compartment contained therein a storage tank for the liquefied gas; an evaporator for evaporating the liquefied gas while delivering the associated cold to the cold room; and an exhaust pipe for the evaporated gas. Background technique [0002] For nearly 40 years, nitrogen has been used to refrigerate refrigerated trucks with multi-chamber systems. This type of method is known as Cryogen Trans (CT). The CT method involves placing cryogenic liquid nitrogen in a vacuum (thermally) insulated container on or in the vehicle. When cooling is required, this nitrogen is pumped through the tube and injected directly into the chamber to be refrigerated using the inherent pressure of the medium. This method is particul...
