Gate Valve
seats a metal wedge agains two metal parts of the valve, and used 
when control is either totally on or totally off, little friction loss 

70
Globe Valve
used when flow is variably and frequently controlled like at a faucets 
or hose bib, friction loss is high 

71
Angle Valve
screw a washer down against a seat to shut the flow off, or opened 
and regulated flow by screwing progressively away from the seat metering of flow 
restriction capability, used mostly for plumbing fixtures 
. Typical hose valve
72
Check Valve
works automatically by allowing water to flow in one direction, 
backflow causes the valve to close, typically used to prevent sanitary waste from 
flowing back into a potable water supply 

73
Ball Valve
allows one way flow, is opened/closed by pressure on a ball that fits into 
a cup shaped opening, used for regulating flow 

74
Butterfly Valve
allows one way flow, mechanism is like a rotating disk attached to a 
spindle used for isolating or regulating flow 

75
Relief Valve
used to control or limit the pressure in a system by allowing fluid to 
divert an alternate rout allowing the pressure to drop, then the valve closes

Water Cement Ratio Facts
Water-cement ratio is based on volume, not weight Low water to cement ratio reduces shrinkage of concrete, increases durability, and strength, and more resistant to freezing and thawing The strength of concrete remains the same for a given water-cement ratio, regardless of amount of aggregate. Principle factors affecting strength of concrete are water-cement ratio and extent of hydration Length of time of moist curing affects strength and water tightness
94
Air-Entrained Concrete
contains billions of microscopic air cells per cubic foot. These air pockets relieve internal pressure on the concrete by providing tiny chambers for water to expand into when it freezes.
95
pH Scale
Ranges from 1 to 14. 1 to 6.9 acidic, 7.1 to 14 are alkaline

98
Electric
``` Description Radiant heat is run through panels or wires to rooms Pros Low initial cost Simple system Can turn on only in occupied room Cons Expensive life cycle cost Wasteful ``` Etc. Baseboard heat uses convection to heat spaces
99
Single Duct
Description A single supply duct runs to all rooms with a constant air flow Rate of air flow is controlled by a damper at each diffuser Controlled by one thermostat Pros Lower cost Less ductwork Returns can be ducted or open in the space between the ceiling and floor/ roof above, called a plenum Easy to operate Good for controlling IAQ Cons Can only heat or cool Only works when loads are similar through a building Bad for perimeter zones in cold climates Thick distribution trees Can be noisy Etc. Typical residential system
100
"Double Duct aka “Dual Duct” aka “High Velocity” "
Description Combination of two single duct systems, one for hot air, and one for cold air Two streams are joined at a mixing box controlled by a thermostat in the zone Pros Can heat and cool at the same time Constant airflow volume Good for perimeter zones Easy to install Good for linear buildings Cons Twice as much ductwork (one to heat, one to cool) Both boiler and chiller have to run all the time The most energy is consumed with this system large fans) noisy distribution Etc. Hot and cold air produced Each room has a thermostat which mixes air in box before entering room Common in hospitals Mostly replaced by VAV systems
101
Multizone
Description Like a Double Duct system, but the mixing box is in the mechanical room Premixed air is sent to each zone Pros Efficient with a few zones Separate duct runs, nothing is shared Easy to sub monitor Cons Lots of ductwork is required Not efficient with many zones or non-square building Etc. Good for mall spaces where each tenant has control Good for square building plans with few zones Used in medium sized buildings
102
Variable Air Volume
Description Air is heated or cooled at a central location and distributed through a single duct. Thermostat controls a damper at each zone to control the volume of conditioned air into that space. Pros Can heat and cool different zones at the same time Most common and efficient system Saves energy because it doesn’t have to run peak all the time Cons Can’t heat and cool different rooms in the same zone at the same time A maintenance nightmare! Requires a lot of interstitial space Etc. Can be single or multiple single duct systems A zone can be one or many rooms System is set to handle hottest or coldest room and rest adjust Used in large buildings where temp regulation is required
103
Unitary
Description A self contained unit where air comes directly in from the outside, conditioned and sent into the space Pros Use when ducts are impracticable to run Each unit can have it’s own utility bill Cons One unit is required for each zone Etc. Can run on just electric, but can also connect to hot/cold piping They’re the units you see in big box stores
104
Reheat (Constant Volume)
Description Return air and fresh outside air are combined and cooled and dehumidified Distributed in constant volume at a low temperature Pros Humidity and temperature can be controlled Ducts are smaller Fan horsepower is lower Cons Uses more energy because primary air volume needs to be cooled most of the time and reheated Etc. Terminal: equip. located near conditioned space Zone: coils are located in ducts to serve an entire zone Economizer Cycle: outside air can be used when temps are low enough
105
Induction
Description Air is supplied to a building under high pressure/ velocity to each induction unit Outside air is mixed with recirculated conditioned air ``` Pros Ducts are smaller Cons Works best in perimeter rooms of multi story multi room buildings Need extra distribution for water ``` Etc. Perimeter zoned areas: schools, offices, labs
106
Hydronic Single Pipe
Description single supply and return pipe hot water is circulated through each register and back to the pipe ``` Pros Low initial cost Simple Cons Can’t go very far because water temp drops Can only heat or cool at one time first register will be hot, the next a little cooler, etc ``` Etc. Can be combined with a forced air system, or stand alone
107
Hydronic Two Pipe
Description Like a Single Pipe System, but separate supply and return pies are used Pros Doesn’t put used water (that’s cooler) into the supply line for the next register Cons Can only heat or cool at one time Etc. Can be combined with forced air system, or stand alone
108
Hydronic Three Pipe
Description Like a 2 Pipe system, but both hot and cold water are mixed in a common return pipe Pros Can heat and cool at the same time Cons Mixes cold and warm water in return pipe Less efficient than a two/four pipe system Etc. Can be combined with forced air system, or stand alone
109
Hydronic Four Pipe
``` Description Like (2) two pipe systems, but there’s one for hot and one for cold Pros Can heat and cool at the same time Cons More expensive due to piping Etc. Can be combined with forced air system, or stand alone ```
110
Fan Coil
Description Combination Hydronic Four Pipe system and constant air volume that can heat and cool at the same time A boiler and chiller each attached to a two-pipe system AND ductwork for the supply air Pros One of the most efficient systems Versatile because it can provide heating and cooling simultaneously Cons High initial cost Highest installation cost because there’s ductwork and plumbing involved Etc. Sends clean conditioned air through a single duct A fan blows air over a hot or cool coil in each room Can be just used for ventilation without heating/ cooling activated
111
Heat Pump
Description Water is circulated through the building, each zone has a heat pump and fan and short ducts that recalculates air within that zone Pros Good efficiency Reduces extensive ductwork Returns over 200% its electrical input when outdoor temp is above freezing Cons High initial cost May need chiller to cool water if all zones are cooling simultaneously May need a boiler to reheat up water Etc. Each zone has its own heat pump and fan Pump either removes heat from water and blows it into a room or removes heat from a room and into the water
112
