In a two-stage refrigeration system, what is the first stage compressor known as?

In a two-stage refrigeration system, the first stage compressor is referred to as a booster. This compressor is responsible for initially compressing the refrigerant from a low pressure to a medium pressure level. The purpose of the booster is to effectively increase the pressure of the refrigerant before it moves to the second stage of compression. By doing so, it optimizes the efficiency of the overall refrigeration cycle, allowing for better heat absorption and transfer in the evaporator.

The functionality of the booster is crucial because it sets the stage for the second stage, which does the final compression to the high-pressure state. The design of having a two-stage system with this kind of arrangement facilitates improved performance and helps in reducing the load on the second stage compressor.

Understanding the terminology used in refrigeration systems is important for engineers and technicians, as it not only helps in identifying the components but also assists in troubleshooting and optimizing the system's efficiency.
