To keep your industrial facility productive, comfortable for workers, and operate efficiently for equipment, you need to maintain an even flow of air. Many factories, warehouses, and manufacturing facilities have issues associated with uneven flow of air, creating hot, cold zones etc, that impact how they operate on a day-to-day basis. Poor distribution of air in large areas will increase utility costs, lower HVAC performance, and shorten the life of a piece of machinery.
By being aware of the potential causes of an uneven flow of air within a facility, facility managers will be able to catch them early and put in place the right ventilation strategy for their facility. Utilizing the advanced industrial air movement products developed by companies such as Marut Air will allow businesses to provide a more homogeneous building environment and improve overall plant performance.
Why is Air Flow Important in An Industrial Facility?
Industrial buildings are typically comprised of large open floor areas, high ceilings, and multiple machines that create heat in the space. These characteristics contribute to the difficulty of having an even flow of air throughout the facility.
Airflow in an industrial facility is needed for:
- Temperature maintenance
- Comfort of workers
- Indoor air quality
- Humidity control
- Cooling of equipment
- Energy savings
When the flow of air is not even, certain areas can be too warm, while some areas may be too cool, creating an inefficient and uncomfortable working place.
Common Causes of Uneven Airflow in Industrial Facilities
- Improperly designed HVAC
HVAC (Heating, Ventilation, and Air Conditioning) systems are one of the leading causes of uneven airflow. An improperly sized or configured system will send too much air to one area and not enough to another. Some problems associated with improperly designed HVAC systems include:
(a) Ductwork that is incorrectly sized,
(b) Diffusers that are badly placed,
(c) Insufficient air return
(d) Fans that are undersized,
(e) Inadequate ventilation.
The end result of an improperly working system is that the imbalances in airflow in all areas of the building will only get worse with time.
- Blocked or Dirty Air Ducts
Blocked air ducts from dust, dirt, and industrial debris will also restrict airflow and may be the reason that certain parts of the building are not receiving air. Common signs of blocked ducts are as follows:
(a) weak airflow from vents,
(b) excessive buildup of dust,
(c) increased utility bills,
(d) uneven temperatures throughout the building.
Removing dust and debris from the air ducts on a regular basis will continue to promote the distribution of air effectively and efficiently.
- High Ceiling Stratification
Buildings that are greater than 20 feet in height have the ability to create thermal stratification (the natural rising of heated air) due to the higher ceiling height. The effect of thermal stratification is twofold. First, the warm air is trapped near the ceiling. Second, the cooler air is located adjacent to the floor. These two effects can cause:
(a) Increased heating costs, and
(b) Employees to be uncomfortable due to the large temperature differential from the ceiling to the floor.
Destratification fans can be used to create a more balanced temperature by forcing the warmer air back down to the floor.
- Obstructed Airflow Paths
Obstructed airflow paths through equipment (racks and partitions), items that are stored within a building, or physically obtrusive items (such as racks or temporary barriers) can result in the obstruction of airflow throughout a work environment.
Some examples of obstructed airflow include:
- Shelving
- Machinery
- Temporary/portable barriers
- Wall partitions
- Obstructions can result in restricted airflow.
- Incorrect Vent Placement
Vents must be placed properly so that supply vents and return vents can maintain balanced air circulation. The improper placement of vents can cause:
- Dead air spaces
- Pressure imbalances
- Temperature fluctuation
- Drained HVAC efficiency
When they are not performing properly, a professional may be able to provide suitable airflow and correct the venting problems.
The leakage of air from a ductwork system is an inefficiency in a ducted-type ventilation system that prevents conditioned air from effectively reaching where it should be directed.
The result of air leaks from ducts includes:
- Decreased airflow
- Increased energy costs
- Loss of pressure
- Decreased cooling effectiveness
- Sealing air leaks improves consistency of airflow.
- Aging Ventilation Equipment
The efficiency of aged ventilation equipment becomes less and less effective as time goes by. Potentially worn out components of equipment include:
- Fan motors
- Bearings
- Dampers
- Belts
- Filters
An aged ventilation system may not effectively provide industrial-type ventilation.
- Negative Air Pressure Issues
A building may experience negative pressure when it has exhausted more air than it has supplied through ventilation systems. The negative pressure could potentially lead to:
- Imbalance of airflow
- Infiltration of dust
- Difficulty opening doors
- Temperature zones that are not balanced
Maintaining proper pressure balance is important for managing indoor air quality.
The Influence of Heat-Producing Machinery on Air Flow in Industrial Facilities
The heat generated by industrial machinery can greatly affect air flow patterns. The following list outlines some of the main sources of heat in industry:
- Compressors
- Welding equipment
- Furnaces
- Ovens
- Manufacturing or assembly lines
These sources of heat produce localized hot spots that disrupt normal air circulatory patterns. If there is not sufficient control over air flow, then the heat produced by the equipment can become distributed unevenly throughout a facility.
The Negative Effects of Uneven Air Flow in Industry
There are many ways in which uneven air flow will negatively impact industrial operations.
Reduced Employee Productivity
Employees who are working in hot spots may experience:
- Fatigue
- Confusion
- Discomfort
- Decreased ability to concentrate
Improving air circulation will enhance both the working conditions and the performance of workers within an industrial environment.
Increased Energy Costs
An HVAC system must work harder when there is poor overall air flow; therefore, a facility will incur:
- Higher electricity costs
- More frequent repair expenses
- Shorter service life of equipment
- Waste of energy
Balanced air flow will reduce the amount of money that is spent on utilities.
How Heat-Producing Equipment Affects Airflow
Sensitive machinery can malfunction if the area where it is located becomes too hot; therefore, when the air flow within a facility is poor, it can lead to:
- Equipment failure
- Product quality issues
- Motor Issues
- Increased down time
Sufficient cooling will assist in the dependable operation of machinery and equipment.
Indoor Air Quality Concerns
Inadequate air flow can trap:
- Dust
- Smoke
- Fumes
- Moisture
- Odors
