ESCO Air Conditioning Practice Exam

The sequential order of steps in the vapor compression process are

1. Condensation, Vaporization, Expansion, Compression

2. Compression, Condensation, Expansion, Vaporization

3. Expansion, Condensation, Vaporization, Compression

4. Vaporization, Expansion, Compression, Condensation

The correct answer is: Condensation, Vaporization, Expansion, Compression

In the vapor compression process of an air conditioning system, the correct sequential order of steps is condensation, vaporization, expansion, and compression. Starting with condensation, the high-pressure, high-temperature refrigerant gas releases heat and condenses into a high-pressure liquid. Next is vaporization, where the high-pressure liquid expands into a low-pressure gas by absorbing heat from the surrounding air. Then comes expansion, where the low-pressure gas expands further, leading to a drop in temperature and pressure. Finally, compression involves compressing the low-pressure, low-temperature gas back into a high-pressure, high-temperature state to continue the cycle. This sequence is essential for the efficient operation of the vapor compression cycle in air conditioning systems.
