Sagility Interview Questions and Answers

VRF and VRV systems are advanced HVAC systems that control the flow and volume of refrigerant to multiple indoor units, providing energy efficiency and individualized comfort.

• VRF and VRV systems use variable-speed compressors to control the flow of refrigerant based on the heating or cooling needs of different zones.

• These systems can simultaneously heat and cool different areas of a building, providing individualized comfort and energy savings.

• VRF systems are more commonly us...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 needed.

• Examples include split case centrifu...read more

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

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

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

• Plumbing services: Water supply, drainage, sewage systems

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 fault, single-phase fault) when calculating fault current.

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