Study Notes
Boilers and HVAC Systems
- Boilers primarily create steam for heating purposes in buildings.
- HVAC systems encompass heating, ventilation, and air conditioning to maintain indoor air quality and comfort.
Electrical Infrastructure
- Cable trays protect and support wiring over long distances in large commercial and industrial buildings.
- Conductors, typically made of copper or aluminum, distribute electricity throughout a building.
- Conduits protect exposed wiring from physical damage, ensuring electrical safety.
Refrigeration Systems
- Condensers release heat to the surrounding area as part of the refrigeration cycle.
- Evaporators cool the surrounding area by absorbing heat from the refrigerant.
- Refrigerants are crucial for absorbing and releasing heat in refrigeration systems.
Elevator Operations and Safety
- Occupant evacuation elevators are designed for buildings exceeding 420 ft (128 m) in height, facilitating safe exits during emergencies.
- Phase I elevator operation involves recalling elevators to the first floor lobby upon smoke detector activation.
- Phase II allows fire fighters to control elevators using special keys, enhancing the efficiency of rescue operations.
- Phase III involves occupants using elevators for self-evacuation before fire fighter assistance arrives.
Emergency Power Systems
- Emergency power provides electricity for critical life-safety features, such as fire pumps and alarm systems, during outages.
- Standby power supports less critical building functions when the main power source fails.
Electrical Control Systems
- Electrical service panels manage circuit conductors and power supply, centrally controlling the electrical system's safety and functionality.
- Cable trays and conduits play essential roles in protecting and organizing electrical wiring within a building.
