In a two stage centrifugal air conditioning system, the liquid refrigerant passes through the condenser directly to what component?

Correct Answer: Option C — economizer

In a two-stage centrifugal system, the economizer acts as an intermediate pressure vessel. Liquid refrigerant from the condenser enters the economizer, where a portion flashes into vapor to cool the remaining liquid before it reaches the evaporator, thereby increasing the overall efficiency and cooling capacity of the refrigeration cycle.
