Refrigerator truck

The present invention relates to a refrigerator truck with thermal insulation walls, especially for the trans « port of perishable goods by road or on the train.

Well-known vehicles of this type are old ice and water cooled, which is divided into two at the ends of the drive. witness arranged ropes, the old electrical driven fans are combined, with the electrical energy being driven by the wheels Generators is generated. The cells often have to be supplied with old ice, which sloh costs and wastes time brings. In addition, it is often difficult to load ice

create.

The cells occupy a space that could be used for the payload and which is lost, even if the cart is used for non-perishable goods. The ice cells ensure neither a constant and adjustable temperature, nor do they allow to adjust the degree of humidity.

The present invention has the purpose of avoiding the disadvantages indicated above.

"According to the invention, the vehicle has two groups

of air conditioners by as many by the Wheels of the vehicle moving electrical generators or by actuating some other means with an external Luftkiihluxigskrelalauf.

The air conditioning groups are advantageous outside the end walls of the car body and appropriately attached in an elevated, but accessible position. she do not name the interior of the vehicle,> which is completely available for the charge.

The cooling air circuit can be formed between a frontal and a side opening or at least under such conditions that the - by the way, forced - air circulation is favored.

Although the two can fully self-contained systems »“ Provide a sufficient degree of security anyway a system that can replace another that may have failed, a safety device that cold

generated, in particular Kittels liquid nitrogen, provided ₉ uta in case of damage in advised to come.

Oa * vehicle can also by means of plug for Operation of the two Klimaanla ^ e ^ 'groups from the outside are supplied fro old energy to uie autoraatiscfi ^ electrical systems during the standstill periods dee to power the vehicle.

With the arrangement described it is possible to regulate both the temperature of the tea and the degree of humidity of the interior of the vehicle, while the need to procure ice and the corresponding poles of a random supply cause both the insufficiency of getting egg and because of one Avoid negligence on the part of the responsible staff. No internal external demands are required insofar as the air conditioning unit can be housed outside the car, and therefore full use is made of the volume of the vehicle for both the transport of perishable goods and the transport of normal goods. On the other hand, there is very convenient and practical accessibility to the refrigeration groups through the usable space of the vehicle without the need for openings in the car body or without the need to maintain or repair the fan groups in any way as having to _$ today the vehicles formed from water it £ ümr case.

On the other hand, an emergency system can always be old liquid gas, such as e.g. liquid nitrogen in combination both air conditioning groups «n provided».

The invention should now proceed to volume of the description and illustrated in the accompanying drawing which shows a practical example of the invention.
