Essential Interview Questions For Boiler/Chiller Technician
1. Explain the working principles of a boiler and a chiller?
- Boiler: A boiler is a device that generates hot water or steam by burning fuel. It consists of a combustion chamber, a heat exchanger, and a water tank. The fuel is burned in the combustion chamber, and the heat produced is transferred to the water in the heat exchanger. The heated water is then stored in the water tank and used to heat buildings or provide hot water for domestic use.
- Chiller: A chiller is a device that removes heat from water or air. It consists of a compressor, a condenser, an evaporator, and a refrigerant. The compressor compresses the refrigerant, which increases its pressure and temperature. The refrigerant is then passed through the condenser, where it releases its heat to the surrounding air or water. The cooled refrigerant is then passed through the evaporator, where it absorbs heat from the water or air being cooled. The refrigerant is then returned to the compressor, and the cycle repeats.
