CONSTITUTION: The cabinet of a refrigerator or freezer comprises one or several hermetically sealed heat insulated spaces 14, which are wall or door panels of a cabinet. The space communicates with a vacuum creating device 18 via an evacuation conduit 17. A vacuum generation apparatus is a permanently installed unit in the cabinet, which is arranged to be activated when or after the cabinet has been installed by the user of the cabinet.
