Ferring Pharmaceuticals Hvac Engineer Interview Questions, Process, and Tips

HVAC system stands for Heating, Ventilation, and Air Conditioning system, which is used to control the temperature, humidity, and air quality in a building.

• HVAC systems regulate indoor air quality by providing ventilation, maintaining temperature, and controlling humidity levels.

• They consist of components such as furnaces, air conditioners, heat pumps, ductwork, thermostats, and air filters.

• Examples of HVAC systems inc...read more

Periodic qualification involves obtaining certifications and licenses to ensure competency and compliance with industry standards.

Chiller is a device that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle.

• Chiller absorbs heat from a process water stream and transfers it to a refrigerant.

• The refrigerant then carries the heat to the condenser where it is released.

• The chilled water is circulated through the building to cool the air or equipment.

• Chillers can be air-cooled, water-cooled, or evaporatively cooled.

• Commo...read more

Maintain differential pressure by adjusting airflow, sealing leaks, and monitoring equipment.

• Adjust airflow using dampers or variable frequency drives to balance pressure

• Seal leaks in ductwork or building envelope to prevent pressure loss

• Monitor equipment regularly to ensure proper functioning and make adjustments as needed

Cooling tower discharge pressure is the pressure at which water is discharged from the cooling tower.

• Cooling tower discharge pressure is typically measured in pounds per square inch (psi) or inches of water column (in. WC).

• The discharge pressure is influenced by factors such as the flow rate of water, the height of the cooling tower, and the design of the tower.

• Maintaining the correct discharge pressure is important fo...read more
