Q

Unit Lock

A

Unit locksets are not regularly used. A rectangular notch is cut into the door and the single-piece unit lock is installed into the opening then tightened.

Q

Cylindrical Lock

A

“Cylinder locksets are most common in residential applications, but they are also used in institutional and office spaces. A hole is bored into the face of the door and A second hole is bored through the door edge and into the first hole. the main lock Cylinder shaft is installed into the larger hole. After, the smaller latch Cylinder is installed into the edge hole.”

Q

Water Cement Ratio Facts

A

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
Q

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

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

Cons
Can only heat or cool at one time
Etc.
Can be combined with forced air system, or stand alone

108
Q

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
Q

Hydronic Four Pipe

A 
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
Q

Fan Coil

A

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
Q

Heat Pump

A

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
