Technical Knowledge Interview Questions

1. Explain the refrigeration cycle in an HVAC system.

How to Answer:

To effectively answer this question, start by providing a concise overview of the four main stages of the refrigeration cycle: compression, condensation, expansion, and evaporation. Explain the role of each component, such as the compressor, condenser, expansion valve, and evaporator. Use clear and simple language to illustrate your understanding.

Sample Answer:

"The refrigeration cycle is the fundamental process in an HVAC system. It begins with the compressor, which compresses low-pressure, low-temperature refrigerant gas, raising its temperature and pressure. The high-pressure gas then flows into the condenser, where it releases heat and condenses into a high-pressure liquid. Next, the liquid refrigerant passes through the expansion valve, where it undergoes a sudden drop in pressure, causing it to evaporate and absorb heat from the surroundings in the evaporator. Finally, the low-pressure gas returns to the compressor to start the cycle again."

What to Look For:

Look for a clear and accurate explanation of the refrigeration cycle, including the understanding of each component's function. Candidates should demonstrate their knowledge of how temperature and pressure changes occur during the cycle.

2. What is the purpose of a heat exchanger in an HVAC system?
