In an A/C system, which component is positioned immediately after the metering device?

• A. Evaporator
• B. Condenser
• C. Compressor
• D. Receiver Dryer

Answer: (A)

In a vapor‑compression air conditioning cycle, the metering device throttles the high‑pressure liquid, dropping its pressure and temperature. The component that follows this throttling action is the evaporator, where the low‑pressure refrigerant absorbs heat from the space and boils into a vapor. This absorption of heat in the evaporator is what provides cooling. The condenser is before the metering device, the compressor is earlier in the loop, and the receiver/dryer is in the liquid line before the metering device, not after it.
