What does the compressor control to manage the low side boiling temperature?

The compressor plays a critical role in managing the refrigeration cycle by controlling the pressure within the system. By adjusting the pressure on the low side, the compressor effectively influences the boiling temperature of the refrigerant.

As pressure decreases, the boiling point of the refrigerant also decreases. This means that the refrigerant can absorb heat at lower temperatures, which is essential for refrigeration. Therefore, through its operation, the compressor maintains the desired balance of pressure to ensure the low side of the system operates at the correct boiling temperature for optimal heat absorption and overall system efficiency.

In the context of ammonia refrigeration, managing the low side pressure is integral for maintaining appropriate cooling levels in the evaporator. The other options, while relevant to the refrigeration process, do not directly influence the boiling temperature in the same fundamental way that pressure control does within the compressor's functionality.
