Cafe Coffee Day Technician Interview Questions and Answers

The refrigeration cycle is a process in which a refrigerant absorbs heat from a low-temperature area and releases it in a high-temperature area.

• The refrigeration cycle starts with the refrigerant entering the compressor as a low-pressure gas.

• The compressor then compresses the refrigerant, raising its temperature and pressure.

• The high-pressure, high-temperature refrigerant gas then flows into the condenser where it rele...read more

A chiller plant typically goes through multiple cycles to cool a building or facility.

• A chiller plant usually has multiple cycles throughout the day to maintain the desired temperature in a building.

• The number of cycles can vary depending on factors such as the size of the building, weather conditions, and cooling load.

• For example, a chiller plant in a large office building may go through several cycles during peak hou...read more

A PCB in a machine is called a printed circuit board.

• A PCB is a flat board made of non-conductive material with conductive pathways etched or printed onto it.

• It provides mechanical support and electrical connections for electronic components.

• PCBs are commonly used in machines and devices to facilitate the flow of electricity and control the functions of the machine.

• Examples of machines that use PCBs include computers, ...read more

Components in PCB are electronic devices that are mounted on the board to perform specific functions.

• Components can be active or passive

• Active components require a power source to function, while passive components do not

• Examples of active components include transistors, diodes, and integrated circuits

• Examples of passive components include resistors, capacitors, and inductors

Tools required for opening a machine depend on the type of machine. However, some common tools include screwdrivers, pliers, wrenches, and hammers.

• The type of machine being opened will determine the specific tools needed

• Common tools include screwdrivers, pliers, wrenches, and hammers

• Other tools may include pry bars, wire cutters, and socket sets

• It is important to have the correct size and type of tool for the job to av

• Identify the specific issue with the electrical wiring that is causing the lights to malfunction

• Repair or replace any damaged wires or components in the electrical system

• Test the repaired wiring to ensure that the lights are functioning properly after the repair

• Ensure that all safety protocols ...read more

HT line refers to high tension line used for transmitting electricity over long distances.

• HT line is used for transmitting electricity at high voltages to reduce energy losses during transmission.

• These lines are typically supported by tall towers to keep them at a safe distance from the ground.

• Examples of HT lines include overhead power lines used by electric utilities to distribute electricity.

• HT lines are crucial for...read more

LT line refers to Low Tension line, which is a distribution line carrying electricity at a lower voltage.

• LT line carries electricity at a voltage lower than 1000 volts.

• It is used for distributing electricity to residential and small commercial buildings.

• LT lines are typically overhead lines supported by poles or underground cables.

• Examples of LT lines include power lines in residential neighborhoods and small businesse
