What are the steps of the vapor compression process?

• A. Compression, Evaporation, Expansion, Circulation
• B. Compression, Condensation, Expansion, Vaporization
• C. Compression, Condensation, Circulation, Refrigeration
• D. Compression, Expansion, Evaporation, Heat Transfer

Answer: (B)

The vapor compression process involves a sequence of stages through which refrigerant undergoes phase changes and pressure variations to transfer heat effectively. The steps typically outlined in the process include: 1. **Compression**: The refrigerant, initially in a low-pressure gaseous state, is compressed by the compressor. This increases its pressure and temperature, transforming it into a high-pressure gas. 2. **Condensation**: The high-pressure gas then passes through the condenser coil, where it releases heat to the surrounding environment. As it loses heat, the refrigerant changes from a gas to a liquid state, a process known as condensation. 3. **Expansion**: The high-pressure liquid refrigerant then flows through an expansion valve or device. This device reduces the pressure of the refrigerant, allowing it to expand and cool significantly as it exits into the evaporator. 4. **Vaporization**: Finally, the low-pressure liquid refrigerant enters the evaporator coil, where it absorbs heat from the indoor air, causing it to evaporate and turn back into a gas, completing the cycle. In summary, the correct sequence of steps highlights the mechanical work done on the refrigerant and the thermal exchanges that enable the cooling effect in HVAC systems. Understanding this process
