Which outcome occurs when the throttling valve leaks during an active refrigeration cycle?

A)Reduced evaporator cooling capacity occurs
B)Increased power consumption at compressor
C)Superheated refrigerant entering expansion valve
D)Elevated condenser pressure with poor cooling

💡 Explanation

When a throttling valve leaks, high-pressure refrigerant bypasses the evaporator. This reduces the pressure differential which reduces the temperature drop during the phase transition. Therefore less cooling occurs, because bypassing means that less refrigerant evaporates and contributes, rather than cooling efficiently in designed quantity.
