20110112797 | Efficiency monitoring of a compressor - A method for monitoring the efficiency of a compressor is provided. A mass flow, an entry pressure, an exit pressure, an entry temperature, and an exit temperature of the process medium are all determined and a performance factor is ascertained. At the inlet of each stage, a stage entry temperature and a stage entry pressure are directly or indirectly measured as measurement parameters. At the outlet of each stage, a stage exit temperature and a stage exit pressure are directly or indirectly measured as measurement parameters. Each stage is assigned a module which calculates a stage efficiency as a performance factor from the measurement parameters using a calculation means. | 05-12-2011 |

20100155039 | DOMESTIC APPLIANCE WITH AN OPEN AIR DUCT - A domestic appliance includes an open air duct and a flow cross-section adjuster in the air duct for adjusting a flow cross-section of the air duct. The flow cross-section adjuster includes rotatably mounted blades for noise dampening purpose. The air duct and the flow cross-section adjuster are in a cooling air inflow region relative to a heat exchanger or a compressor of the domestic appliance. | 06-24-2010 |
20110000097 | HOME DEVICE FOR DRYING LAUNDRY COMPRISING A COMPONENT AROUND WHICH PROCESS AIR CAN FLOW - A domestic appliance for drying laundry having a component around which process air flows. The component has a substrate made of metal and the substrate has a surface facing the process air. The surface carries a coating that prevents adhesion of foreign particles and the coating has a surface energy of no more than 40 mN/m. The surface has a section that is directly impinged by the process air and that is essentially completely covered by the coating. The component has edges in the section covered by the coating and each of the edges is essentially completely covered by the coating. | 01-06-2011 |
