Klimatisierbehälter

The invention relates to an air-conditioning container with an air-conditioning chamber surrounded by a chamber housing of the air-conditioning container.

Such air conditioning containers are among others as

Camping accessories offered and used. The

Air-conditioning containers have an air-conditioning device for cooling or heating the air-conditioning chamber, wherein Peltier temperature control devices with Peltier elements are usually used. In the known

Klimatisierbehältern is the Peltier element with a first side on an outer surface of the Klimatisierbehälters and is connected to a first side opposite the second side of a heat conducting body to improve the heat conduction. Alternatively or in addition to the heat-conducting body fans are also often provided. If the Peltier temperature control device is used for cooling, the first side is cool and the second side is warm. When heating, the first side is warm and the second side is cool.

Such Peltier temperature control devices are preferably used in transportable air conditioning containers, since the Peltier temperature control devices have a comparatively small size and a comparatively low weight. In addition, for the operation of Peltier

Temperature control no cooling gases or cooling liquids required, as they are usually used for the operation of refrigerators. Also, the required in refrigeration machines usually compressor is not required for the operation of a Peltier temperature control.

A disadvantage of the known Peltier tempering is the low efficiency, which leads to a relatively high electrical power consumption with only a small cooling or heating power. Conventional air-conditioning containers with Peltier temperature control devices are therefore provided with electrical power connections in order to be able to supply the air-conditioning containers with energy as permanently as possible from an electrical power network. Camping air conditioning containers can usually alternatively be operated on a 12 volt DC power supply as well as on a 220/240 volt AC power supply.

If no power supply to the Peltier temperature control is possible over a longer period of time, the internal temperature of the air conditioning chamber is equal to the

Outside temperature of the environment, so that warmed, for example, stored in the air-conditioning refrigerated goods. The heat exchange takes place via the outer surfaces of the chamber housing with the environment. In order to keep the required temperature in the air conditioning chamber as long as possible in a desired or permissible temperature control range, even when the Peltier temperature control device is not operated, the chamber housings are usually made thermally insulated in order to lower the heat transfer coefficient of the chamber housing.

However, an insulation of the region of the chamber housing, on the outer surface of which the Peltier element is present, is not possible or desired in order not to influence the heat exchange via the Peltier element. When the Peltier temperature control device is switched off, therefore, there is a considerable input of heat or cold via the Peltier temperature control device into the air conditioning chamber.

As an object of the invention, it is considered to further develop the air conditioning container known from the prior art so that the temperature in the air conditioning chamber remains as long as possible in the predetermined temperature range even when the air temperature control device is switched off.
