Other uses might include dispensing of fluids or medicine. Dispenser holds food or beverage package while being filled with either cold or room-temperature water. Dispenser provides measured amount of water for reconstituting dehydrated foods and beverages. Pressure regulated and flow timed to control amount dispensed. The numerous engineering challenges as well as human factors and safety considerations during the concept, design, and prototyping are outlined in this paper. Providing potable-quality water at the proper temperature for food and beverage reconstitution is critical to maintaining crew health and well-being. ![]() It will be the size of two stacked Shuttle Middeck lockers (approximately the size of two small suitcases) and integrated into a science payload rack in the U.S. The unit is designed to remain functional for up to ten years with replacement of limited life items such as filters. This quantity will allow three to four crewmembers to rehydrate their food and beverages from this location during a single meal. A heater assembly contained within the unit will be able to supply up to 2.0 liters of hot water (65 to 93oC) every thirty minutes. ![]() The unit will provide potable-quality water, including active removal of biocidal iodine prior to dispensing. It will receive iodinated water from the Fuel Cell Water Bus in the U.S. The PWD is designed to provide incremental quantities of hot and ambient temperature potable water to U.S. This unit will provide additional potable water dispensing capability to support an onorbit crew of six. A new United States On-orbit Segment (USOS) Potable Water Dispenser (PWD) is under development. All ISS crewmembers rehydrate Russian and U.S. The International Space Station (ISS) Russian Segment currently provides potable water dispensing capability for crewmember food and beverage rehydration.
