10+ Finvasia Interview Questions and Answers

Quality circle method is a problem-solving technique that involves a group of employees working together to identify, analyze, and solve work-related issues.

• Involves a group of employees working together

• Focuses on identifying, analyzing, and solving work-related issues

• Encourages employee participation and collaboration

• Uses brainstorming sessions and data analysis to come up with solutions

• Promotes continuous improvement and employee empowerment

Refrigeration is the process of removing heat from a space to lower its temperature, commonly used in refrigerators to preserve food.

• Refrigeration involves the transfer of heat from a low-temperature space to a high-temperature space.

• Refrigerators use refrigeration to keep food cold and prevent spoilage.

• Common refrigerants used in refrigeration systems include Freon, ammonia, and carbon dioxide.

The part in the refrigeration cycle responsible for absorbing heat from the indoor air is the evaporator coil.

• Evaporator coil is located inside the indoor unit of the HVAC system.

• It contains refrigerant that evaporates as it absorbs heat from the indoor air.

• The evaporator coil is where the cooling process begins in the refrigeration cycle.

• Once the refrigerant absorbs heat, it is sent to the compressor for further processing.

A type of chiller commonly used in HVAC systems is the centrifugal chiller.

• Centrifugal chillers use the principle of centrifugal force to cool water or air.

• They are typically used in large commercial buildings or industrial facilities.

• Examples of centrifugal chillers include Trane CenTraVac and Carrier AquaEdge.

Refrigeration cycle is a process in which a 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 through the expansion valve, where it expands and cools down befo...read more

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

• Compressors are commonly used in HVAC systems to compress refrigerant gases.

• There are different types of compressors such as reciprocating, rotary, and scroll compressors.

• Compressors play a crucial role in the cooling process by circulating refrigerant through the system.

• The compressor is often referred to as the 'heart' of an HVAC system.

Centrifuse is not a recognized term in the HVAC engineering field.

• Centrifuse is not a commonly used term in HVAC engineering.

• It is possible that the interviewer may have misspoken or meant to ask about centrifuge, a device used for separating fluids based on density.

• If unsure, it is best to ask for clarification from the interviewer.

Selecting a pump involves considering factors like flow rate, head pressure, efficiency, and system requirements.

• Determine the required flow rate for the system

• Calculate the head pressure needed to overcome friction and elevation changes

• Consider the efficiency of the pump to minimize energy consumption

• Select a pump that meets the system requirements and is compatible with the fluid being pumped

In plant maintenance, repairing works involve identifying issues, planning repairs, sourcing materials, executing repairs, and conducting quality checks.

• Identify the issue or problem that needs to be repaired

• Plan the repair process including scheduling and resource allocation

• Source necessary materials, tools, and equipment for the repair

• Execute the repair work following safety protocols and guidelines

• Conduct quality checks to ensure the repair was successful

Refrigeration is the process of cooling a space or substance below room temperature, while a refrigerator is a device that uses this process to store food and drinks at a cold temperature.

• Refrigeration involves removing heat from a space or substance to lower its temperature

• Refrigerators use a refrigeration system to keep food and drinks cold

• Common refrigerants used in refrigeration systems include Freon and ammonia

• Refrigerators have components such as compressors, condensers...read more
