Device for controlling the temperature of objects and method for controlling a device for controlling the temperature of objects

A method for controlling a device for controlling the temperature of objects, the method comprising the following steps:

• a) determining of a temperature of external air;
• b) setting of an external air volumetric flow through a cooling air discharge line, which external air volumetric flow can be temperature controlled via a heat exchanger;
• and
• c) setting of a volumetric flow ratio between a volumetric flow which flows into the heat exchanger from a cooling region and a volumetric flow which flows into the heat exchanger from a temperature control device in a manner which is dependent on the temperature of the external air, wherein
• a device controlled comprises a temperature control space, the cooling region which is connected to the temperature control space, the temperature control device for generating temperature controlled temperature control space air, and the heat exchanger which has an external air feed line, a warm air feed line which is connected to the cooling region and the temperature control device, and the cooling air discharge line which is connected to the cooling region.
