SUMMARY
Refrigerators utilize hydrofluorocarbon fluids due to their low specific heat capacity and low liquid/gas transition points, making them effective for heat transfer. Ideal gases, such as noble gases (e.g., Helium and Neon) or natural air, cannot be used in refrigeration systems because they lack intermolecular forces, which are crucial for condensation and efficient heat exchange. While any real gas can theoretically be used, practical applications favor gases that operate safely and economically within the desired temperature ranges. The choice of refrigerant is influenced by the operational temperature of the refrigerator and the surrounding environment.
