MEP systems final
A boiler that has water flow through a series of tubes that are heated by hot combustion
gases which surrounds them within the tank. - ANS-water-tube
A duct accessory which acts as a valve (or plate) for regulating the flow of air out of the duct.
- ANS-Damper
A fire suppression sprinkler system where the heads are always open but the pipe is not
pressurized. When a valve is released due to the detection of a fire, all of the heads release
water until the valve is closed. - ANS-Deluge
A forced -air system used for both heating and cooling, which moves heat from the
surrounding air either into, or out of, a building depending on the need. It does not generate
additional heat (no combustion) but requires a moderate climate to be efficient. - ANS-Heat
pump
A heat rejection device (or mechanical unit) which is used in the air conditioning system and
mixes air with cooling water to reduce the temperature of the water and physically remove
the heat from the system out into the atmosphere. - ANS-Cooling tower
A hydronic system which has a single, continuous pipe that feeds each of the terminal
devices on the system, and continues on as the return pipe back to the boiler. - ANS-Series
loop system
A mechanical component in a steam heating system that recovers heat that would otherwise
be lost throughout the system to pre-heat the boiler feed water. - ANS-Economizer
A one-line diagram is - ANS-a drawing that shows how all of the circuits get connected
(installed) within a system that is not to scale.
A rating given to material or assemblies to resist its ability to catch and spread fire -
ANS-Flame spread
A specific electrical practice and procedure to safeguard employees from the unexpected
energization or startup of machinery and equipment, or the release of hazardous energy
during service or maintenance activities. - ANS-lockout/tagout
A system of electrical conductors in a generating or receiving station on which power is
concentrated for distribution. Typically used for high current power distribution. - ANS-bus
bar
A two-pipe hydronic system which has a supply and return line, and the return line provides
the shortest path back to the boiler for the liquid (first unit supplied is the first unit returned,
and vice versa). - ANS-Direct return system
A type of fire suppression system where the pipes are filled with pressurized air (or nitrogen)
instead of the suppression medium. - ANS-Dry pipe system
A type of fire suppression system which activates the medium prior to the opening of
sprinkler heads so it will fill the pipes and be prepared to suppress a fire as soon as the
sprinkler head releases. - ANS-pre-action system
A type of forced air unit which does not require ductwork, heats only single areas, and is
common in areas that aren't utilized full-time or is inefficient to run a ducted mechanical
system to on a regular use basis. - ANS-CUH (cabinet unit heater)
A type of lamp that is a form of incandescent lighting made by using quartz instead of class,
and has a much smaller envelope to produce light. - ANS-Halogen
, A type of pump that uses a double-suction propeller, and is often used in larger applications
where higher flow rate and higher pressure are required is known as a: - ANS-Horizontal
split case pump
A vertical (typically) piping system within a building (usually a stairwell) used to connect fire
hoses to for additional support in suppressing a fire - ANS-Sand pipe or a fire riser
Adjusts speed of the electrical drive (piece of the system that controls speed of
motion/rotation) and torque by varying the motor frequency and voltage input. - ANS-VFD
(variable frequency drive)
Advantages of using Incandescent light bulbs - ANS-Easy to make/produce, and relatively
inexpensive
Advantages of using led lights - ANS-highly efficient, very long life span, temperature
resistant, and generally environmentally friendly (non-toxic materials)
After electricity is generated at a power plant, what is the first major component the electric
current goes to? - ANS-step-up transformer substations
After the domestic cold water lines pass the meter, it typically will split and branch into
multiple locations. What are possible locations that the cold water will go to? - ANS-Streight
to fixtures, to water heater, to boiler, to hose bibbs
Air conditioning is the process of controlling which 2 climate factors - ANS-heat and humidity
Although the term "low voltage" can be subjective with its designation, in the construction
industry LV typically refers to systems that require less than how many volts? - ANS-50
An apparatus used to connect fire hoses to on the outside of the building so that the fire
department can pump additional water into the building for fire suppression. - ANS-Fire
Department Connection (FDC)
An electric current which reverses direction periodically (and regularly). - ANS-Alternating
current
An electrical box/enclosure used to house wiring connections, to protect these connections
and provide a safety barrier. - ANS-Junction box
An electrical safety switch used to ensure the electrical circuit is completely de-energized to
a load. Usually only able to switch while no-load is present. Isolated to individual pieces of
equipment. - ANS-disconnect
An encasement (usually metal or concrete) designed to protect and consolidate cabling for
distribution to and from buildings. - ANS-Duct bank
An energy exchange (heat released or absorbed) required to convert a material from one
state of matter to another (i.e. solid to a liquid to vapor). - ANS-Latent heat
Any temperature added to a gas above the boiling point of its liquid state. - ANS-Superheat
Automatically operated electrical safety device protecting against overcurrent. Detects fault
from too much current and automatically switches to break a circuit. Can be reset after it has
"tripped" for reuse. - ANS-Circuit breaker
Calculates cooing and heating capacity over a certain time - ANS-Btuh
Component (or mechanism) that is responsible for the physical act of moving, or carrying
out, a command within a system (e.g. opens a valve if told to). - ANS-actuator
Component that takes input for a monitoring/measuring device, and decides what command
to send out for resolution. - ANS-controller
Daylight harvesting is: - ANS-a system that uses natural light to offset the amount of
electrical lighting needed to properly light a space.
Device for monitoring water level in a steam boiler, which is installed so that the lowest level
visible in the device is above the low (danger) level in the boiler. - ANS-Glass gauge
