Q

Tube in tube

A

Coil and cleanble

Water flows in the inner tube

Refrigerant in outer tube

In opposite to maximize transfer rate

A

Heat from discharge gas causes minerals to come out of solution

Cannot be cleaned mechanically in tube in tube

16
Q

Natural draft

A

Often made of redwood fiber glass and galvanized

No blowers to move air through

17
Q

Forced draft

A

Air is pushed through tower

18
Q

Induced draft

A

Air is pulled though tower

19
Q

Draft Tower

A

As water falls through the tower air is moved across it to aid cooling

20
Q

Evaporative Condensors

A

Inside cooling tower

Makeup system replaces evaporated water

21
Q

Evaporative condensors

A

Both air and water used to desuperheat condense and subcool refrigerant

Water allowed to escape regularily

22
Q

Air cooled

A

Air absorbs heat in difficult places

Anywhere discharge

About 30F or higher

23
Q

High efficiency

A

Allows systems operate at lower pressures

As low as 10F than outside ambience

24
Q

condensing temperature drops

A

Ambient temp drops
