Question

Quizplus · Accepted Answer

A low-ambient control is necessary to ensure proper operation of the refrigeration system during colder months when the outdoor temperatures drop below the optimal range for cooling. The other options, relief valves and EEPR valves, are safety devices that protect the system from overpressure, and oversized evaporator coils may not be necessary for year-round operation.
