AHU components refer to the various parts of an Air Handling Unit that work together to regulate and circulate air in a building.
Filters - to remove dust and particles from the air
Coils - for heating or cooling the air
Fans - to circulate the air
Dampers - to control the flow of air
Humidifiers/dehumidifiers - to adjust the humidity levels
Centrifugal blowers are commonly used in AHUs for their efficiency and ability to handle high volumes of air.
Centrifugal blowers are preferred for AHUs due to their ability to handle high volumes of air efficiently.
They are more energy efficient compared to other types of blowers.
Examples of centrifugal blowers commonly used in AHUs include forward curved, backward inclined, and airfoil designs.
Primary pump is the main pump responsible for the majority of the pumping work, while secondary pump is a backup pump used in case the primary pump fails.
Primary pump is the main pump in a system, while secondary pump is a backup pump.
Primary pump is responsible for the majority of the pumping work, while secondary pump is used only when needed.
Examples: In a heating system, the primary pump circulates hot water throug...
AHU valve connection refers to the connection of valves in an air handling unit for controlling the flow of air.
AHU valve connection is essential for regulating the flow of air in an air handling unit.
Valves are typically connected to the AHU ductwork to control the amount of air entering or exiting the unit.
Properly connected valves ensure efficient operation of the AHU system.
Examples of AHU valves include damper val
Chilled water pipe size requirements depend on flow rate, pressure drop, material, insulation, and system design.
Flow rate: Determine the required flow rate of chilled water in the system.
Pressure drop: Calculate the pressure drop to ensure efficient operation.
Material: Select appropriate pipe material based on temperature and pressure requirements.
Insulation: Insulate the pipes to prevent heat gain or loss.
System desi...
The chiller connection refers to the method by which a chiller unit is connected to a building's HVAC system.
Chiller connection typically involves piping to transport chilled water from the chiller to the building's air handling units.
The connection may also include electrical wiring for power supply and control signals.
Proper chiller connection is crucial for efficient cooling and proper functioning of the HVAC system
I applied via Approached by Company and was interviewed before Feb 2022. There were 2 interview rounds.
The refrigeration cycle is a process that removes heat from a space and transfers it to the external environment.
The refrigeration cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.
The compressor compresses the refrigerant gas, raising its temperature and pressure.
The high-pressure refrigerant then flows to the condenser, where it releases heat to the surroundings and conden...
A chilled water system is a cooling system that uses chilled water to remove heat from a building or process.
Chilled water systems use water as a cooling medium.
They typically consist of a chiller, chilled water pumps, and a distribution system.
Chilled water is circulated through coils or heat exchangers to cool air or equipment.
Chilled water systems are commonly used in large commercial buildings, data centers, and in...
Types of pumps include centrifugal pumps, reciprocating pumps, and rotary pumps.
Centrifugal pumps use centrifugal force to move fluid through a system.
Reciprocating pumps use a piston or diaphragm to create pressure and move fluid.
Rotary pumps use rotating mechanisms to transfer fluid.
Other types of pumps include gear pumps, peristaltic pumps, and vane pumps.

Rate analysis for building items involves calculating the cost of materials, labor, and overhead for each item in a construction project.
Rate analysis helps in determining the cost of each building item based on material and labor costs.
It involves breaking down the total cost into components like material cost, labor cost, and overhead expenses.
Rate analysis helps in estimating the total project cost accurately.
For ex...
Material rates of building materials vary based on factors like location, quality, and demand.
Material rates can vary based on the location of the construction site.
The quality of the building materials can also impact the rates.
Demand for certain materials can cause fluctuations in prices.
For example, the rate of cement in urban areas may be higher compared to rural areas.
Higher quality bricks may cost more than lower...

The thickness of subgrade varies depending on the type of construction and soil conditions.
The thickness of subgrade is determined based on the load-bearing capacity required for the structure.
It is typically measured in inches or centimeters.
For example, in road construction, the subgrade thickness can range from 6 to 12 inches.
In building construction, it may vary from a few inches to several feet depending on the bu
