Lupin Apprentice Trainee Interview Questions, Process, and Tips

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume.

• Compressors are commonly used in refrigeration and air conditioning systems.

• They work by taking in low-pressure gas and compressing it to a higher pressure.

• This compression process reduces the volume of the gas, resulting in an increase in pressure.

• Compressors can be classified into positive displacement and dynamic types.

Latent heat is the heat energy absorbed or released during a phase change without a change in temperature.

• Latent heat is the energy required to change the state of a substance without changing its temperature.

• It is absorbed or released during phase changes such as melting, boiling, or condensation.

• Latent heat is responsible for the cooling effect of sweating.

• Examples include the heat absorbed when ice melts into water ...read more

The type of condenser used in domestic air conditioners is typically the air-cooled condenser.

• Air-cooled condensers are the most common type used in residential air conditioners.

• They work by using a fan to blow air over the condenser coils, which helps to dissipate heat.

• This type of condenser does not require a separate water source for cooling.

• Examples of air-cooled condensers include the coil and fin condenser and th

The capillary tube is a component in the refrigeration cycle that helps regulate the flow of refrigerant.

• The capillary tube is a small, narrow tube made of copper or aluminum.

• It is located between the condenser and the evaporator in the refrigeration system.

• Its main function is to restrict the flow of high-pressure liquid refrigerant from the condenser to the low-pressure evaporator.

• By creating a pressure drop, the cap...read more

The refrigeration cycle is a process that removes heat from a space and transfers it to the external environment.

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

• The liqu...read more
