Expansion Block/Orifice Tube: Description and Operation
The component serves as a throttling device to lower the pressure and temperature of the refrigerant to enable it to be evaporated at room temperature.
The refrigerant leaving the tube is mostly in liquid form and at low temperature (approx. 3 - 6 °C)/37.4 - 42.8 °F)
From the expansion tube, the refrigerant passes to the evaporator.
