Star Health & Allied Insurance Interview Questions and Answers

VRF and VRV systems are advanced HVAC systems that provide individual control over the temperature in different zones of a building.

• VRF and VRV systems use refrigerant to transfer heat between the outdoor unit and multiple indoor units.

• They are energy-efficient as they can vary the flow of refrigerant based on the heating or cooling requirements of each zone.

• VRF systems are typically used for larger buildings with multiple zones, while VRV systems are a specific brand name fo...read more

Different types of pumps used in fire fighting systems include centrifugal pumps, positive displacement pumps, and vertical turbine pumps.

• Centrifugal pumps are commonly used in fire fighting systems due to their high flow rates and efficiency.

• Positive displacement pumps are used for high pressure applications where a constant flow is required.

• Vertical turbine pumps are used in situations where space is limited and a vertical pump is necessary.

• Examples include end suction cent...read more

MEP services include mechanical, electrical, and plumbing systems in a building.

• Mechanical services: HVAC systems, ventilation, heating, and cooling

• Electrical services: Lighting, power distribution, fire alarm systems

• Plumbing services: Water supply, drainage, sewage systems

• Integration of MEP systems for efficient building operation

Fault current can be calculated using Ohm's Law and the impedance of the system.

• Calculate the total impedance of the system, including both the source impedance and the impedance of the fault location.

• Use Ohm's Law (I = V/Z) to calculate the fault current, where I is the fault current, V is the voltage, and Z is the total impedance.

• Consider the type of fault (e.g. three-phase, single-phase) when calculating fault current.

• Fault current can also be calculated using software too...read more
