Which component is responsible for converting high-pressure refrigerant vapor into a high-pressure liquid by dissipating heat to the ambient air?
- ACompressor
- BAccumulator
- CCondenser
- DEvaporator
Show answer & explanationAnswer & explanation
Correct answer: C. Condenser
The condenser, typically located at the front of the vehicle, dissipates the heat absorbed by the refrigerant, causing it to change state from a hot, high-pressure vapor to a high-pressure liquid.
Why the other options are wrong
- A. The compressor increases the pressure and temperature of the refrigerant vapor.
- B. The accumulator separates liquid from vapor and stores excess refrigerant on the low-pressure side in orifice tube systems.
- D. The evaporator absorbs heat from the cabin and converts liquid refrigerant to vapor.
Condenser Function
The condenser is a heat exchanger that converts high-pressure refrigerant vapor into high-pressure liquid by releasing heat to the surrounding air.
- Located on the high-pressure side of the system.
- Usually in front of the radiator.
- Facilitates heat transfer from refrigerant to ambient air.
- Essential for the phase change from vapor to liquid.
Memory trick: Condenser cools down, evaporator cools in.
