Four ways to optimize the ventilation system - with suggestions for immediate measures 

30 August 2024

The ventilation system is one of the biggest energy consumers in many companies, especially in the manufacturing industry. By optimizing the ventilation system, companies can not only reduce their energy consumption but also improve the working environment for their employees. Here are concrete tips and measures to optimize the ventilation system and save energy.

1.

Carry out a ventilation survey and perform regular maintenance

Map air flows and energy consumption

Map the entire ventilation system to identify where air flows are greatest and where improvements can be made.

Regular cleaning and service

Change and clean ventilation filters regularly and perform maintenance on fans and motors to ensure optimal function. Note that the correct type of ventilation filter should be used.

Immediate action
Check operating hours

Check the operating times of the fans to ensure that the system is only operating when it is really needed.

Clean and inspect

Clean filters and inspect ducts to ensure they are free of obstructions and leaks. ​

2.

Use energy efficient components

Install energy efficient fans

Replace old fans with energy-efficient models with higher efficiency.

Implement Variable Speed ​​Drives (VFDs)

Install fan and pump speed control equipment to adjust flow as needed.

Immediate action
Reduce speed

Reduce fan speed during periods of low load to reduce energy consumption.

Calibrate

Calibrate thermostats and sensors to ensure they function correctly and do not cause unnecessary energy consumption.

3.

Optimize the control system

Automatic control systems

Use automatic control systems to adjust ventilation flow based on real-time data on temperature, humidity and air quality.

Time control

Use time control to ensure that the ventilation system is only in operation when needed.

Immediate action
Adjust

Adjust thermostats and sensors to ensure they function properly and do not cause unnecessary energy consumption.

4.

Recycle energy

Install heat recovery systems

Recover heat from outgoing air and use it to preheat incoming air, reducing the need for heating.

Cooling recovery

Use cooling recovery systems to recover cold from exhaust air and reduce the need for cooling during hot months.

Immediate action
Investigate heat recovery

Investigate the possibility of heat recovery.

5.

Reduce air leaks and improve insulation

Improve the building's airtightness

Make sure the building is well insulated and airtight to prevent unwanted air leaks that can affect the efficiency of the ventilation system.

Insulate ventilation ducts

Insulate ventilation ducts to minimize heat loss and improve overall system efficiency.

Immediate action
Find leaks

Inspect and seal any leaks in the ventilation system to improve efficiency.

Insulation of ventilation ducts

Check and improve the insulation of ventilation ducts where possible.

By implementing these measures, companies can optimize their ventilation systems and achieve significant energy savings. An energy-efficient ventilation system not only contributes to lower energy costs, but also improves the working environment and the company's sustainability performance.
