The metering device in a refrigeration system reduces the pressure and saturation temperature of the liquid refrigerant before it enters the evaporator. This process allows for efficient heat absorption during cooling. The correct option is 'Reduces the pressure and saturation temperature of liquid refrigerant'.

The metering device in a refrigeration system controls the flow of refrigerant and reduces its pressure before it enters the evaporator. This process allows for efficient evaporation and heat absorption, which is vital for cooling. Types of metering devices include thermostatic expansion valves and capillary tubes. ;
