Refrigeration Systems
Refrigeration systems are devices that transfer heat from a low-temperature region to a high-temperature region, using mechanical work, electric power, or other sources of energy. In the context of space and astronautical engineering, refrigeration systems are essential for maintaining the temperature and humidity levels of spacecraft, habitats, and life support systems. They are used to cool electronic equipment, food, water, and other supplies, as well as to remove excess heat generated by human metabolism and machinery. Refrigeration systems in space must be designed to operate in vacuum, microgravity, and extreme temperature conditions, and to withstand radiation, vibration, and other environmental stresses. They may use different types of refrigerants, such as ammonia, carbon dioxide, or water, and different cooling methods, such as vapor compression, thermoelectric, or radiative cooling.
