The different types of ducts in air conditioning include rectangular ducts, round ducts, flexible ducts, and spiral ducts.
Rectangular ducts are commonly used and are made of sheet metal.
Round ducts are used for better airflow and are made of galvanized steel.
Flexible ducts are easy to install and are made of a flexible plastic material.
Spiral ducts are used for large commercial applications and are made of galvanized s

Plinth height calculation for equipment involves determining the required height of the equipment's base or foundation.
Factors to consider include equipment weight, vibration, accessibility, maintenance requirements, and safety regulations.
Calculations may involve structural engineering principles, load-bearing capacity, and equipment specifications.
Example: For an HVAC unit, plinth height calculation would consider...
Yes, I can do pump head and ESP calculations.
Pump head calculation involves determining the total dynamic head (TDH) of a pump system.
ESP (External Static Pressure) calculation is used in HVAC systems to determine the pressure required to move air through ductwork.
Both calculations require knowledge of system parameters such as flow rate, pipe diameter, pipe length, and friction losses.
Formulas and equations are used t...

A centrifugal compressor is a type of dynamic compressor that uses a rotating impeller to increase the pressure and flow of a gas.
It works by converting kinetic energy into potential energy.
It is commonly used in HVAC systems, gas turbines, and refrigeration systems.
It is more efficient than positive displacement compressors for high flow rates and low pressure differentials.
It can be single-stage or multi-stage, depen...
Chillers are machines that remove heat from a liquid via a vapor-compression or absorption refrigeration cycle.
Components include compressor, condenser, evaporator, expansion valve, and refrigerant.
Types of chillers include air-cooled, water-cooled, and absorption chillers.
Chillers are commonly used in HVAC systems for cooling large buildings or industrial processes.
I applied via Referral and was interviewed in Jul 2021. There was 1 interview round.
The chiller refrigeration cycle is a process that removes heat from a space or substance using a refrigerant.
The cycle starts with the compressor compressing the refrigerant gas.
The compressed gas then flows through the condenser where it releases heat and becomes a liquid.
The liquid refrigerant then flows through the expansion valve, where it expands and becomes a gas again, absorbing heat in the process.
The gas then ...
