Which should be fitted after a compressor burnout?
Oil separator
Solenoid valve
TEV
Suction drier
Answer explanation
A suction drier should be fitted after a compressor burnout because it helps remove contaminants, such as acids and moisture, from the refrigerant system. This prevents further damage to the compressor and other components. Oil separators, solenoid valves, and TEVs are not specifically designed for this purpose and would not be the appropriate choice after a compressor burnout.

5) A Evaporator Pressure Regulator (EPR) is designed to
Maintain a constant crankcase pressure
Maintain a constant subcooling value
Maintain a minimum evaporating pressure/Temperature
Maintain a minimum evaporator superheat
Answer explanation
The question asks about the function of an Evaporator Pressure Regulator (EPR). The correct answer is that an EPR is designed to maintain a minimum evaporating pressure. This means that the EPR ensures the pressure in the evaporator does not fall below a certain level, which is crucial for the proper functioning of the system.
