What is the main purpose of a filter dryer in a refrigeration system?

• To cool the refrigerant

• To reduce the flow of the refrigerant

• To filter and dry the refrigerant

• To increase the pressure of the refrigerant

What can happen if moisture and dirt are not filtered and dried from the refrigerant?

• Corrosion of internal surfaces and parts

• The refrigerant will become more efficient

• The compressor will work more effectively

• The refrigeration system will run at optimal conditions

How often should the filter dryer be replaced in a refrigeration system?

• Every 5 years

• Every 2 years

• Only when it fails

• Every 6 months

Where are filter dryers typically installed in a refrigeration system?

• In the evaporator

• In the suction line after the expansion valve

• In the liquid line between the condenser and expansion valve

• In the compressor

What is the purpose of the sight glass in relation to the filter dryer?

• To indicate the refrigerant flow direction

• To indicate the presence of moisture in the system

• To indicate the refrigerant pressure

• To indicate the refrigerant temperature

What material is the main casing of the filter dryer made from?

• Plastic

• Steel

• Copper

• Aluminum

What is the purpose of the spring inside the filter dryer?

• To hold the core in a fixed position

• To increase the pressure of the refrigerant

• To cool the refrigerant

• To absorb moisture from the refrigerant

What is the function of the perforated plate inside the filter dryer?

• To capture dirt particles

• To allow the refrigerant to flow to the outlet

• To keep all the internal parts in position

• To absorb moisture

What is the purpose of the molecular sieve in the filter dryer?

• To distribute the internal pressure evenly

• To capture large dirt particles

• To absorb moisture and retain acids

• To retain smaller dirt particles

Where can filter dryers be found in a refrigeration system?

• In the evaporator only

• In the liquid line and suction line

• In the discharge line

• In the condenser only
