2: Components Slide of 20
Слайд 3Objectives
In the following slides, we will study the components of
air handling systems in order to:
become familiar with
the componentsknow their functions
become aware of possible problems
Слайд 6 Weather louvre
Silencer
Flow rate controller
Control damper
To prevent insects, leaves, dirt and
rain from enteringTo reduce noise caused by air circulation
Automated adjustment of volume of air (night and day, pressure control)
Fixed adjustment of volume of air
Components (1)
Слайд 7 Heating unit
Cooling unit
/dehumidifier
Humidifier
Filters
Ducts
To heat the air to the proper temperature
To cool the
air to the required temperature or to remove moisture from the airTo bring the air to the proper humidity, if too low
To eliminate particles of pre-determined dimensions and/or micro-organisms
To transport the air
Components (2)

Blocked
Poorly adjusted, bad pressure
differential systemBad water/steam quality/poor drainage
No elimination of condensed water/poor drainage
Incorrect retention rate/damaged/badly installed
Inappropriate material/internal insulator
leaking
