In our previous home, our two girls shared a room and it didn't go so well, since they have opposite personalities and living styles (early-to-bed, night owl; neat freak, slob; loud, quiet). Like any home, the orbiter must be kept clean, especially in space when floating dirt and debris could present a hazard. In addition, you must be able to communicate with each other inside the orbiter or its payload modules and when conducting spacewalks outside. You must be able to talk with flight controllers on the ground daily for the routine operation of the mission. To talk with spacewalkers, the system uses a UHF frequency, which is picked up in the astronaut's space suit. Water from the slurper is moved with air to a fan separator, which uses centrifugal force to separate water from air. After a fire is extinguished, the atmosphere control system will filter the air to remove particulates and toxic substances. Trash is separated into wet trash bags and dry trash bags, and the wet trash is placed in an evaporator that will remove the water. All trash bags are stowed in the lower deck to be returned to Earth for disposal.
Solid waste from the toilet is compacted, dried and stored in bags where it is returned to Earth for disposal (burning). The water is then stored in four water storage tanks located in the lower deck. HP boasts that it features reused furniture and low-flow water fixtures. Drinkable water is then filtered to remove microbes and can be warmed or chilled through various heat exchangers depending upon the use (food preparation, consumption, personal hygiene). However, the electronic equipment generates more than enough heat for the ship. Some polyamorous relationships may involve certain partners having exclusive sexual relationships with each other, while others may allow for more fluidity. While aerodynamic tweaks and suspension settings can give race teams an edge, just about everyone in NASCAR agrees that the engine is the heart of a race car. You can either push to talk and release to listen or have a continuously open communication line. The computers monitor equipment and talk to each other and vote to settle arguments.
It circulates cool water to remove excess heat (cabin air is also used to cool electronic equipment) and transfers this heat to a Freon exchanger. Heat released from the freon causes the ammonia to boil. Ammonia vapor is dumped overboard. Ammonia boiler Freon coolant loops pass through a tank of pressurized ammonia. Radiators - located on the inside surfaces of the cargo bay doors that radiate the collected heat to outer space Flash evaporator/ammonia boilers - these devices are located in the aft fuselage and transfer heat from Freon coolant loops overboard when cargo bay doors are closed or when cargo bay radiators are overloaded. The problem is getting rid of the excess heat. The Freon then transfers the heat to other orbiter systems (e.g., cryogenic gas tanks, hydraulic systems) and radiates excess heat to outer space. The water passes through a hydrogen separator to eliminate any trapped hydrogen gas (excess hydrogen gas is dumped overboard). Excess water produced by the fuel cells gets routed to a wastewater tank and subsequently dumped overboard. Liquid waste from the toilet goes to the wastewater tank where it is dumped overboard. The air is recirculated and the water goes to a wastewater tank.
The water tanks are pressurized by nitrogen so that water can flow to the mid-deck for use by the crew. Timers or sensors are also used to manage traffic flow across a city. For general housecleaning, various wipes (wet, dry, fabric, detergent and disinfectant), detergents, and wet/dry vacuum cleaners are used to clean surfaces, filters and the astronauts. Since the soap you use in the shower is generally less harmful than laundry detergent (it's mild enough to use on your skin), bath water is the most prized gray water for your plants. Besides air, finish my basement water is the most important quantity aboard the orbiter. Outer space is an extremely cold environment and temperatures will vary drastically in different parts of the orbiter. Distribute heat where it is needed on the orbiter (mid-fuselage and aft sections) so that vital systems do not freeze in the cold of space. The cabin heat exchanger also controls the cabin temperature. Pumps, lines, valves - transport the collected heat from one area to another.
