The motor is a device that converts electrical energy into mechanical energy to produce motion.
Motors can be found in various applications such as industrial machinery, household appliances, and vehicles.
There are different types of motors including AC motors, DC motors, and servo motors.
Examples of motors include electric fans, washing machine motors, and car engines.
Speed of three phase induction motor can be controlled by varying the frequency of the power supply.
Speed control of three phase induction motor is achieved by changing the frequency of the power supply.
Lowering the frequency decreases the speed of the motor, while increasing the frequency increases the speed.
Variable frequency drives (VFDs) are commonly used to control the speed of induction motors.
Soft starters can a...
Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.
Types of transformers include step-up transformers, step-down transformers, isolation transformers, auto transformers, and distribution transformers.
Transformers are used to increase or decrease voltage levels in electrical circuits for various applications.
Examples of transformer use inclu...

Sub cooling and superheat are terms used in refrigeration to describe the temperature difference between the refrigerant's actual temperature and its saturation temperature.
Sub cooling is the difference between the refrigerant's actual temperature and its saturation temperature at a particular pressure.
Superheat is the difference between the refrigerant's actual temperature and its saturation temperature at a particula...
E6 error in a split unit can be resolved by checking the air filter, cleaning the coils, and resetting the unit.
Check the air filter for any blockages or dirt buildup
Clean the coils to ensure proper airflow and cooling
Reset the unit by turning it off for a few minutes and then turning it back on
Consult the user manual for specific troubleshooting steps

IPLV stands for Integrated Part Load Value and is a measure of chiller efficiency under varying load conditions.
IPLV takes into account the chiller's efficiency at different operating capacities, providing a more accurate representation of overall efficiency.
It is calculated based on the chiller's performance at 100%, 75%, 50%, and 25% load conditions.
IPLV is commonly used in the HVAC industry to compare the energy eff...
I applied via Walk-in and was interviewed before Aug 2023. There was 1 interview round.
Refrigeration cycle is a process in which refrigerant absorbs heat from a low-temperature area and releases it in a high-temperature area.
Refrigerant absorbs heat from the evaporator coil and evaporates into a gas.
The compressor then compresses the gas, raising its temperature and pressure.
The hot gas flows through the condenser coil, releasing heat and condensing back into a liquid.
The liquid refrigerant passes throug...
Various types of gases are used in different industries and applications, such as oxygen, nitrogen, hydrogen, and carbon dioxide.

The type of chiller used depends on the specific requirements of the system, such as cooling capacity, energy efficiency, and space constraints.
Different types of chillers include air-cooled chillers, water-cooled chillers, absorption chillers, and centrifugal chillers.
The choice of chiller type is influenced by factors such as the temperature range required, the size of the system, and the availability of water for co...
The main compartment in a refrigeration cycle is the evaporator.
The evaporator is where the refrigerant absorbs heat from the air or water being cooled.
It is located inside the refrigerator or air conditioning unit.
The evaporator coils are filled with the refrigerant, which evaporates as it absorbs heat.
The evaporator is connected to the compressor, which then compresses the refrigerant gas to raise its temperature.
Refrigeration works by removing heat from a space or substance to lower its temperature.
Refrigerant absorbs heat from the space or substance being cooled
The refrigerant then moves to the compressor where it is compressed and heated
The hot, pressurized refrigerant moves to the condenser where it releases heat and condenses into a liquid
The liquid refrigerant moves to the expansion valve where it expands and cools down
