• Classification of Expansion Devices in Refrigeration Systems:
• Regulate refrigerant mass flow and reduce pressure from condenser to evaporator:
• (I) Capillary tube: Constant-bore restrictor used in domestic refrigerators.
• (II) Thermostatic Expansion Valve (TEV/TXV): Modulating valve maintaining constant evaporator superheat.
• (III) High-side float valve: Liquid-level float valve discharging condensed liquid to flooded evaporators.
• All three are standard refrigeration expansion devices.
• Conclusion: (I), (II) and (III) (Option 2).

Correct option: (2) (I), () and (Ill)
