The primary purpose of a compressor in an ammonia refrigeration system is to move refrigerant from the low side to the high side of the system and control temperatures. This component plays a crucial role in the refrigeration cycle by increasing the pressure of the refrigerant, which allows it to absorb heat in the evaporator (low side) and then reject that heat in the condenser (high side).

As the compressor compresses the refrigerant vapor, it raises both the temperature and pressure, enabling the refrigerant to flow through the system effectively. This mechanism not only ensures the continuous circulation of refrigerant but also regulates the pressure to maintain optimal operating conditions. By controlling temperatures throughout the refrigeration process, the compressor helps achieve the desired cooling effect in the refrigerated space. This detailed understanding of the compressor's function is essential for efficient operation and troubleshooting in ammonia refrigeration systems.
