Smartworks Project Engineer Interview Questions, Process, and Tips

Q1. Chiller efficiency
Ans. 
Chiller efficiency is a measure of how well a chiller unit is able to cool a space while using the least amount of energy.
• Chiller efficiency is typically measured by the Coefficient of Performance (COP), which is the ratio of cooling output to energy input.

• Regular maintenance and cleaning of chiller components can improve efficiency.

• Upgrading to a more energy-efficient chiller model can also increase efficiency.

Q2. Which one more efficiently? Air cooled,or water cooled???
Ans. 
Water cooled systems are generally more efficient than air cooled systems due to higher heat transfer capabilities.
• Water has higher heat transfer capabilities compared to air

• Water cooled systems can maintain more consistent temperatures

• Water cooled systems are typically used in high performance applications such as data centers and industrial machinery

Q3. How we improved duct velocity?
Ans. 
Duct velocity can be improved by increasing the fan speed or reducing the duct size.
• Increase the fan speed to increase the air velocity in the duct.

• Reduce the duct size to increase the air velocity.

• Use dampers or adjustable louvers to control and optimize the airflow.

• Ensure proper sealing of duct joints to minimize air leakage.

• Consider using smooth and straight ducts to reduce friction and improve airflow.

• Regularly cle...read more

Q4. What types of gas use chiller system?
Ans. 
The chiller system uses various types of gases for cooling purposes.
• Common types of gases used in chiller systems include R-134a, R-410A, and ammonia.

• R-134a is a hydrofluorocarbon (HFC) refrigerant commonly used in air conditioning systems.

• R-410A is a blend of hydrofluorocarbons used as a replacement for older refrigerants.

• Ammonia (NH3) is often used in industrial chiller systems due to its high cooling capacity.

• Other ...read more

Q5. How we decided the vrf system capacity as per area??
Ans. 
The VRF system capacity is determined based on the area's cooling and heating load requirements.
• Calculate the total cooling load and heating load for the area

• Consider factors such as insulation, windows, occupancy, and equipment

• Select VRF system capacity based on the calculated load requirements

• Consult with HVAC professionals for accurate sizing
