This inline restrictor tube serves as a specialized metering or flow-control device inside the closed-loop refrigeration system. It’s this narrow restriction that helps regulate the specific flow-rate of the refrigerant moving between the condenser and evaporator coils. By limiting the volume and velocity of the refrigerant, it maintains thermal equilibrium during the freeze cycle. This effectively ensures a uniform ice sheet thickness across the evaporator plates.
Note: The restrictor doesn’t show in the newer R290 or R449 parts manuals for the models identified above. It’s possible it was either overlooked or it is simply no longer used. Presently, there’s no clarity on the matter. If you find that the CIM model being serviced has a restrictor tube and it needs to replaced, then this is likely the component you’ll need for the repair.
