How to reduce the electricity costs of your HVAC System
TYPICAL LIFE CYCLE COSTS OF A FINE PARTICLE FILTER OF THE ISO EPM1 GROUP
Clean air yes, but at low cost please!
Why do we actually talk about energy consumption all the time? When it comes to filter costs, most people first think of the purchase price. However, that is fundamentally a mistake!
The image shows why: only about 10% of the life-cycle costs of an air filter are accounted for by the purchase price – about 80%, on the other hand, by its energy consumption.
A cheaply purchased filter can therefore become much more expensive in the long run.
Your checklist to reduce energy cost in your HVAC system:
There are various standards that apply to ventilation and air-conditioning technology. For general HVAC systems, this is often DIN EN 16798 Part 3 or VDI 3803 and VDI 6022. Always plan the system and air filter according to the rules for the specific application. Seek expert assistance if necessary.
A higher fan speed means higher energy consumption. Don’t set the air flow rates higher than required for the application. Good to know when planning: more air filter elements per filter stage help to reduce the required air volume.
The easiest way to reduce the energy consumption of your system: when choosing a filter, always pay attention to the energy efficiency class. Even with existing systems, replacing filters is usually not a problem.
Demand-oriented regulation of HVAC systems saves a lot of energy and increases the service life of the air filters. Intelligent air quality management systems analyse and optimise your system based on real-time data, and even help you in planning your filter changes and capacities.
Sounds paradoxical at first: multiple filter stages usually consume less energy than single filters. The reason is that coarser pre-filters effectively protect the following fine particle filters, and thus slow down the increase in pressure drop. You should always pay attention to the technical rules for the particular application.
