Ans. 
Comparison and implementation of data structures and operations in Spark for data engineering
• DataFrames are structured data with named columns, Datasets are type-safe structured data, RDDs are resilient distributed datasets

• Word count can be implemented using Spark transformations like flatMap, map, reduceByKey

• GroupBy is a DataFrame operation, GroupByKey is an RDD operation

• Spark context is the entry point for Spark func...read more

Q1. What are the types of AHU modes
Ans. 
The types of AHU modes include cooling mode, heating mode, and ventilation mode.
• Cooling mode: AHU cools the air before circulating it throughout the building.

• Heating mode: AHU heats the air before circulating it throughout the building.

• Ventilation mode: AHU circulates fresh air throughout the building without heating or cooling.

Q2. Difference between Heatwheel and Energy wheel
Ans. 
Heatwheel and Energy wheel are both types of energy recovery ventilation systems used in HVAC systems, but they differ in their specific mechanisms and applications.
• Heatwheel uses a rotating wheel with a desiccant coating to transfer heat and moisture between incoming and outgoing air streams, while Energy wheel uses a rotating wheel with a matrix of heat-absorbing material to transfer heat only.

• Heatwheel is more effec...read more

Q3. What to we use in primary pump systems if we don't have bypass valve
Ans. 
In primary pump systems without a bypass valve, we can use a variable frequency drive (VFD) to control the pump speed.
• Use a variable frequency drive (VFD) to adjust the speed of the pump based on system demand

• VFDs can help maintain system pressure and flow without the need for a bypass valve

• VFDs can also improve energy efficiency by matching pump speed to actual system requirements

Q4. Types of chiller operating mode
Ans. 
Types of chiller operating modes include constant speed, variable speed, and hybrid mode.
• Constant speed mode: Chiller operates at a fixed speed regardless of load.

• Variable speed mode: Chiller adjusts speed based on load requirements for energy efficiency.

• Hybrid mode: Combines constant and variable speed modes for optimal performance.

• Examples: Centrifugal chillers often operate in variable speed mode for energy savings.
