Abstract: The design and performance of the Skylab thermal and environmental control systems is considered. The Orbital Workshop had a combined active and passive thermal control system. The refrigeration system was designed to store food and biomedical samples and to cool drinking water. The atmosphere control system included active humidity control, molecular sieves and charcoal canisters to control carbon dioxide, odor, and contaminants, and the gas supply system. Mission support preparation, including instrumentation, ground data system, system troubleshooting, and training, is surveyed. Major in-flight anomalies occurred with the thermal control system when the meteoroid shield was lost during SL-1 ascent and when the Airlock Module coolant loop malfunctioned during SL-2 manned operations. The atmosphere control system performed without major anomaly throughout the manned missions.
