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.

A suction line drier is primarily fitted to remove

 Acid

Copper particles

Oil

Wax

Answer explanation

A suction line drier is primarily fitted to remove acid from the refrigeration system. Acid can cause damage to the compressor and other components, leading to system failure. The drier effectively filters out acid, protecting the system and ensuring its efficient operation.

What device is used to protect the compressor flood back

EPR

Oil separator

Suction line accumulator

CPR

Answer explanation

A suction line accumulator is used to protect the compressor from flood back. It collects excess liquid refrigerant and prevents it from entering the compressor, which could cause damage. The other options, EPR, oil separator, and CPR, do not serve this specific purpose.

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.
