Which risk increases when a refrigeration system's liquid-line subcooler is bypassed in high ambient temperature?

💡 Explanation

Bypassing the subcooler increases refrigerant temperature entering the expansion valve, because it inhibits optimal subcooling which introduces flash gas into the evaporator and causes cavitation during compression. Therefore, valve plate damage risk increases, rather than efficient energy absorption.
