What is the primary effect of leaking valves on refrigeration compressors?

Increased refrigerant pressure
Decreased output of the compressor
Enhanced cooling efficiency
Improved compressor lifespan

The correct answer is: Decreased output of the compressor

Leaking valves on refrigeration compressors primarily lead to a decrease in the output of the compressor. When there is a leak, refrigerant can escape from the intended pathways, which disrupts the proper flow and pressure regulation within the system. This results in the compressor being unable to operate efficiently and produce the necessary cooling effect. The compromised seal that leads to a leak reduces the effective volume of refrigerant available for compression, thus lowering the overall capacity and performance of the unit. This situation not only affects the compressor's ability to cool effectively but can also lead to additional strain on the system, as the compressor works harder to compensate for the loss of refrigerant. Understanding this impact highlights the importance of maintaining valve integrity to ensure optimal functioning of refrigeration systems.
