In a two-stage system, which compressor is typically started first?

• A. The low stage compressor
• B. The bypass compressor
• C. The high stage compressor
• D. The auxiliary compressor

Answer: (C)

In a two-stage system, the first compressor that is typically started is the low stage compressor. This compressor is responsible for handling the low-pressure and low-temperature vapor from the evaporator, compressing it to a higher pressure for the subsequent stage in the system. Starting the low stage compressor first ensures that the necessary vapor flow is established in the system. The high stage compressor operates after the low stage compressor has raised the pressure of the refrigerant. If the high stage compressor were to start first, there would be no sufficient vapor to compress, leading to potential damage and inefficiency within the system. Understanding the sequence in which compressors operate is critical to maintaining the integrity and efficiency of refrigeration cycles, particularly in systems designed for optimal performance. This highlights the importance of correct operations and procedures when managing multi-stage refrigeration systems.
