Essential Interview Questions For Service Person
1. What are the key components of a refrigeration system and explain their functions?
The key components of a refrigeration system are:
- Compressor: The compressor is the heart of the refrigeration system. It compresses the refrigerant gas, increasing its pressure and temperature.
- Condenser: The condenser is a heat exchanger that removes heat from the refrigerant gas, causing it to condense into a liquid.
- Expansion valve: The expansion valve controls the flow of refrigerant into the evaporator.
- Evaporator: The evaporator is a heat exchanger that absorbs heat from the refrigerated space, causing the refrigerant to evaporate into a gas.
2. Describe the different types of refrigerants and their applications.
CFCs and HCFCs
- Chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) were the most common refrigerants used in the past.
- However, these refrigerants have been phased out due to their ozone-depleting potential.
HFCs and HFOs
- Hydrofluorocarbons (HFCs) and hydrofluoroolefins (HFOs) are the most common refrigerants used today.
- These refrigerants have low ozone-depleting potential and are relatively efficient.
Natural refrigerants
- Natural refrigerants, such as ammonia, carbon dioxide, and hydrocarbons, are becoming increasingly popular.
- These refrigerants have zero ozone-depleting potential and are very efficient.
3. What are the different types of refrigeration systems?
- Vapor-compression refrigeration systems are the most common type of refrigeration system.
- These systems use a compressor to compress the refrigerant gas, which then condenses, expands, and evaporates to remove heat from the refrigerated space.
- Absorption refrigeration systems use a heat source to generate a refrigerant vapor, which then condenses and evaporates to remove heat from the refrigerated space.
- Thermoelectric refrigeration systems use the Peltier effect to generate a cooling effect.
