If one dropped suction pressure of a refrigeration system, what would NOT happen?

In a refrigeration system, when the suction pressure drops, several changes occur in the system dynamics. The boiling temperature of the refrigerant is directly related to the pressure it is under in the evaporator. As the suction pressure decreases, the boiling temperature also decreases; therefore, the rise in boiling temperature would not happen.

This distinction is crucial because while a decrease in suction pressure leads to a corresponding decrease in the boiling temperature, the other factors—discharge pressure, discharge temperature, and compression ratio—are affected in a rising manner. Specifically, lower suction pressure increases the compression ratio as the compressor has to work harder to move refrigerant from a lower pressure to a higher discharge pressure. Consequently, this increased effort generally leads to higher discharge temperatures as well as higher discharge pressures. Understanding these relationships is vital in maintaining efficient operation and troubleshooting in refrigeration systems.
