What effect does high ambient temperature have on a refrigeration system?

High ambient temperature negatively impacts the efficiency of a refrigeration system. When the outside temperature rises, the system must work harder to remove heat from the refrigerated space because the temperature difference between the inside of the refrigerator and the surrounding environment decreases. This increased workload requires more energy, leading to a decline in the overall efficiency of the refrigeration cycle.

As the ambient temperature rises, the condenser's ability to dissipate heat is also compromised. This can result in higher pressures within the system, forcing the compressor to operate less efficiently and potentially leading to increased wear and tear on the components. In summary, high ambient temperatures mean that refrigeration systems require more energy to maintain proper cooling, thereby decreasing efficiency.
