Schneider Electric BMS Engineer Interview Questions, Process, and Tips

A chiller operates by removing heat from a liquid through a refrigeration cycle and then transferring that heat to the air outside.

• Chiller absorbs heat from a liquid coolant, typically water or a mixture of water and glycol.

• The absorbed heat is transferred to the refrigerant in the evaporator, causing it to evaporate and absorb more heat.

• The refrigerant is then compressed, raising its temperature and pressure, before b...read more

BMS uses BACnet protocol and the baud rate can vary depending on the system.

• BMS typically uses the BACnet protocol for communication

• The baud rate in BMS systems can vary depending on the specific system and requirements

• Common baud rates for BMS systems include 9600, 19200, and 38400
