This was achieved by considering some factors such as economy, availability of components and research materials, efficiency,. So the temperature control system has to carry out two major functions: 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. This system also smoothes out sudden changes in chill water temperature or pressure from the central utility plant. 6 Alarm systems 4. Open output detection prevents system operation without a. Cooling system, apparatus employed to keep the temperature of a structure or device from exceeding limits imposed by needs of safety and efficiency. changeover control was added to the operating system, and the zone damper controls were upgraded to UCM Version 3. Piping and Instrumentation Diagrams (P&IDs) use specific symbols to show the connectivity of equipment, sensors, and valves in a control system.
