Bharat Electronics Apprenticeship Trainee Interview Questions, Process, and Tips

Q1. What is refrigeration cycle
Ans. 
The refrigeration cycle is a process that removes heat from a space or substance to lower its temperature.
• The cycle consists of four main components: compressor, condenser, expansion valve, and evaporator.

• The compressor increases the pressure and temperature of the refrigerant gas.

• The high-pressure gas then flows into the condenser where it releases heat and becomes a high-pressure liquid.

• The liquid refrigerant passes ...read more

Q2. What is air conditioner
Ans. 
An air conditioner is a device that cools and dehumidifies the air in a room or building.
• Air conditioners use refrigeration cycles to remove heat and moisture from the air.

• They consist of components such as compressors, condensers, evaporators, and fans.

• Air conditioners can be used for both cooling and heating purposes.

• Examples of air conditioners include window units, split systems, and central air conditioning system

Q4. Primary secondary and condenser and ahu how to work explain
Ans. 
Primary, secondary, condenser, and AHU are components of a HVAC system.
• Primary and secondary refer to the two sides of a heat exchanger in the HVAC system.

• The primary side carries the hot fluid or refrigerant, while the secondary side carries the cool fluid or air.

• The condenser is a heat exchanger that removes heat from the refrigerant and converts it from a gas to a liquid.

• The AHU (Air Handling Unit) is responsible fo...read more

Q5. How many types of chiller safety are there
Ans. 
There are several types of chiller safety measures that are implemented to ensure safe operation and prevent accidents.
• Safety measures include pressure relief valves to prevent overpressure

• Temperature sensors to monitor and control the chiller's operating temperature

• Flow switches to detect and prevent low or no flow conditions

• High-pressure switches to protect against excessive pressure

• Low-pressure switches to prevent d...read more

Q6. How much in resistance ohms
Ans. 
The resistance is measured in ohms.
• Resistance is a measure of how much a material opposes the flow of electric current.

• The unit of resistance is ohms (Ω).

• Resistance can be calculated using Ohm's Law: R = V/I, where R is resistance, V is voltage, and I is current.

• Resistance can vary depending on the material, length, and cross-sectional area of a conductor.

• For example, a copper wire with a length of 1 meter and a cross-...read more

Q7. How much sensor voltage
Ans. 
The sensor voltage varies depending on the specific sensor and its application.
• Sensor voltage is typically measured in volts (V).

• Different sensors may have different voltage ranges and requirements.

• For example, a temperature sensor may operate within a voltage range of 0-5V.

• Some sensors may require a specific voltage supply, while others may be designed to work with a wide range of voltages.

• It is important to consult t...read more
