Ways of Air Conditioning

1. Vertical Laminar Flow

Vertical Laminar Flow: flow of clean air from the ceiling to the floor, applicable for Class 10-1,000

Advantages

Disadvantages

  1. Comprehensive effect
  2. Not easily affected by personnel and work attitude
  3. Steady state is reached immediately after operation
  4. Very little accumulation and floating dust
  5. easy to manage
  1. Must pay attention to ineffective space on the ceiling, such as lighting (to prevent turbulent flow)
  2. More troublesome to change filter
  3. Very high installation cost
  4. More difficult to expand partition

 

2. Horizontal Laminar Flow

Horizontal Laminar Flow: flow of clean air 80% from the ceiling, 40% to the walls, or the ceiling, applicable for Class 100-10,000

Advantages

Disadvantages

  1. Steady state is reached immediately after operation
  2. Simplified structure
  1. Upstream can affect downstream
  2. Must pay attention to the allocation and management of personnel and equipment
  3. Very high installation cost
  4. More difficult to expand partition

 

3. Turbulent Flow

Turbulent Flow: flow of clean air from filter outlet, to around the floor, applicable for Class 10,000-100,000

Advantages

Disadvantages

  1. Simplified structure
  2. Low installation cost
  3. Easy to expand partition
  4. Can ensure high cleanliness level with the use of clean desks
  1. Due to turbulent flow, contaminated particles may circulate in the air
  2. Must pay attention to the allocation and management of personnel and equipment
  3. Takes time to reach steady state
