  • In 1 and 2 is with 10 a convenli cher control cabinet and its housing 15 referred to in his interior 10a Includes control and automation systems. For air conditioning of the interior 10a of the control cabinet 10 is a cooling unit at least on a control cabinet wall 20 arranged, which is preferably attached to the outer wall surface of the cabinet or on the cabinet door 11 is arranged. Instead of a cooling unit can for air conditioning of the cabinet interior 10a also with a drive device 26 connected fan 25 be provided, the z. B. is designed as a filter fan.
  • Switching the cooling unit on and off 20 or the blower 25 via a control device 30 coming from a contact switch 31 and a contactor 32 that exists with the cabinet door 11 is in operative connection, with the switching on and off of the refrigerator 20 or the blower 25 about the pivoting movement of the cabinet door 11 such that in the closed state of the cabinet door 11 the cooling unit 20 or the blower 25 is in operation, whereas when opening the cabinet door 11 the air conditioner or the blower is put out of operation.
  • The control device 30 is designed as a mechanical device, as a light optical device, as an electronic device or as an electrical device, whereby sensor or sound wave controlled devices and other suitable devices can be used, such. As motion detectors, proximity sensors, acoustic systems u. like.
