Which effect occurs when a refrigeration system uses an overcharge of refrigerant R-134a?

💡 Explanation

When a refrigeration system is overcharged, excessive refrigerant floods the condenser, raising the condensing pressure, further elevating the discharge pressure due to compressor backpressure. Therefore, elevated compressor discharge pressure is the result, rather than changes to evaporator temperature, superheat, or condenser subcooling caused by alternative refrigerant issues.
