Essential Interview Questions For Heating and Cooling Technician
1. Describe the working principle of a refrigeration system?
- In a refrigeration system, a refrigerant absorbs heat from a cold source, such as an evaporator coil in a refrigerator or air conditioner, causing it to evaporate.
- The refrigerant then travels to a compressor, where it is compressed, increasing its temperature and pressure.
- The hot, high-pressure refrigerant then travels to a condenser coil, where it releases heat to a warm source, such as the outside air in an air conditioner or the inside air in a refrigerator.
- The refrigerant then travels to an expansion valve, where it is expanded, causing it to drop in temperature and pressure.
- The cold, low-pressure refrigerant then travels back to the evaporator coil, where it repeats the cycle.
2. What are the common causes of a refrigerant leak?
- Corrosion
- Loose fittings
- Cracked or damaged lines
