Patent number: 8499578Abstract: A water product dispensing system includes a dispenser mounted for selectively releasing a water product, a display provided on the dispenser and a sensor operatively coupled to the dispenser. The dispensing system also includes a sensor for determining a fault condition. In the event that a fault condition exists, the fault condition is presented upon the display only upon operation of the dispensing system. The water product dispensing system also includes a water filter, with the fault condition indicating a need to replace the water filter.Type: GrantFiled: August 18, 2006Date of Patent: August 6, 2013Assignee: Whirlpool CorporationInventors: Nelson J. Ferragut, II, James H. Jenkins, Jr., Craig Lear

Patent number: 8475603Abstract: The invention is directed toward a system and method for sanitizing a condensate drain to reduce sludge and related pathogens. The system is directed to a sanitizing assembly having a treatment chamber connected to the condensate drain, where the treatment chamber includes a top end and a shaft. A spray assembly is positioned proximate to the top end of the treatment chamber. This spray assembly has a nozzle spray connected to a hot water source. A spray controller within the spray assembly helps disperse a sufficient quantity and pressure of hot water within the shaft to dislodge sludge, when necessary.Type: GrantFiled: June 16, 2010Date of Patent: July 2, 2013Inventor: Stewart Kaiser

Patent number: 8464783Abstract: The present invention relates to a method and arrangement of optimizing the level of anti freeze agent in a heat transfer fluid in a heat exchange system The method comprises determining (305) a wanted level of anti freeze agent at least partly based on the temperature of the media to which the heat exchange system will deliver heat, controlling (310) the current level of the anti freezing agent in the heat transfer fluid. Anti freezing agent is added 315:1 to the heat transfer fluid if the current level is a predetermined amount lower than the wanted level, and removed 315:2 from the heat transfer fluid if the current level is a predetermined amount higher than the wanted level.Type: GrantFiled: March 9, 2007Date of Patent: June 18, 2013Inventor: Mikael Nutsos
