Patent number: 8950211Abstract: Subassemblies are arranged in the interior of a closed housing. The housing has an air inlet via which air-conditioning air is guided into the interior of the housing. The housing contains a fan via which the air used for the air conditioning of the subassemblies is guided to the outside from the interior of the housing. In addition to a fan input opening, the fan has at least two fan output openings wherein a rotatably mounted screen is arranged in the interior of the fan. By variably adjusting the position of the screen, the air sucked in via the fan input openings is optically guided via at least one of the fan output openings.Type: GrantFiled: May 14, 2007Date of Patent: February 10, 2015Assignee: Siemens AktiengesellschaftInventor: Harald Kraus

Patent number: 8950209Abstract: A refrigeration system includes an airflow system which eliminates the traditional evaporator fan cover assembly in the freezer area by utilizing at least one air outlet formed between a freezer cavity area and a duct coupled to the fresh food cavity area. The air outlet is configured to permit at least a portion of a cooled air stream generated by a fan of the evaporator assembly received in the freezer cavity area to be provided to the fresh food cavity area through the air outlet and via the duct. The refrigeration system also includes at least one air return formed between the evaporator assembly and the fresh food cavity area. The air return is configured such that air from the fresh food cavity area flows into the evaporator assembly through the air return.Type: GrantFiled: July 10, 2012Date of Patent: February 10, 2015Assignee: General Electric CompanyInventors: Brent Alden Junge, Blake Mackenzie Whelan
