Study Notes

Key Terms in Building Systems

Boiler: A furnace that generates steam for heating applications in buildings.
Cable tray: Elevated structures that facilitate the safe routing of electrical and communication cables over long distances in large commercial and industrial facilities.
Condenser: A refrigeration system component where high-pressure, high-temperature refrigerant releases heat, transitioning from gas to liquid state.
Conductor: Metal elements, typically copper or aluminum, responsible for the distribution of electricity throughout a building.
Conduit: Protective tubes or enclosures that safeguard exposed electrical wiring from damage and environmental hazards.
Diffusion system: A specialized vessel for mixing ammonia with water to reduce ammonia concentration, with the waste disposed of in a sanitary sewer system.
Electrical service panel: A central panel that consolidates circuit conductors and power supply, managing the distribution and control of electricity within the building.
Emergency power: Backup power supplied by generators to sustain critical systems like fire pumps and alarms during outages.
Evaporator: The refrigeration system element where the refrigerant absorbs heat, lowering the temperature of the surrounding air.
HVAC systems: Integrated systems handling heating, ventilation, and air conditioning to maintain indoor climate comfort.
Occupant evacuation elevators: Specialized elevators designed for self-evacuation of individuals in skyscrapers over 420 ft (128 m) tall, supporting Phase III operations during emergencies.

Elevator Operation Phases

Phase I operation: Automatic recall of elevators to the lobby when a smoke detector is activated, allowing occupants to evacuate while keeping doors open for fire fighters.
Phase II operation: Fire fighters can access designated elevators using a key, allowing them to control the elevators for reaching higher floors safely.
Phase III operation: Elevators designated for occupant evacuation in emergencies before fire fighters arrive, facilitating safe evacuation procedures.

Refrigeration and Power Terms

Refrigerant: A fluid that circulates within refrigeration systems, absorbing heat in the evaporator and releasing it in the condenser.
Standby power: Generated power that supports non-critical building operations during outages, ensuring essential functions can continue without interruption.
