In a two-stage refrigeration system, where would you find the booster compressor?

In a two-stage refrigeration system, the booster compressor is strategically positioned between the evaporator and the intercooler. This placement is logical as the primary function of the booster compressor is to increase the pressure of the refrigerant vapor that comes from the evaporator. By compressing the refrigerant at this stage, it prepares the vapor for further cooling in the intercooler, where it can be condensed before entering the main compressor.

The flow of refrigerant in a typical two-stage system allows for more efficient cooling and improved capacity. The booster compressor plays a crucial role in enhancing the system's efficiency by extracting more energy from the low-temperature refrigerant, which would otherwise not be utilized as effectively. Thus, its position is essential for optimizing the overall performance of the refrigeration cycle.
