Top 10 Questions for Absorption Operator Interview

1. Explain the principle of operation of an absorption refrigeration system?

• The absorption refrigeration system uses a refrigerant and an absorbent to create a cooling effect.
• The refrigerant is evaporated in an evaporator, and the vapor is absorbed by the absorbent.
• The heat of absorption is removed by a cooling water stream.
• The refrigerant-absorbent mixture is then pumped to a generator, where heat is added to drive off the refrigerant vapor.
• The refrigerant vapor is then condensed in a condenser, and the heat of condensation is removed by a cooling water stream.
• The condensed refrigerant is then expanded through an expansion valve, and the resulting cold refrigerant vapor is used to cool the space to be refrigerated.

2. What are the different types of absorption refrigeration systems?

Vapor-absorption systems

• Use a refrigerant that is a gas at low pressure and a liquid at high pressure.
• The most common type of absorption refrigeration system.

Absorption-compression systems

• Use a refrigerant that is a liquid at low pressure and a gas at high pressure.
• More efficient than vapor-absorption systems, but also more complex.

3. What are the advantages and disadvantages of absorption refrigeration systems?

Advantages
