26/01/29: One key reason for this is the use of blanket reserves for design conditions, air volumes and treatment stages.
Plans are often based on extreme weather conditions that rarely occur during normal operation. For example, the summer design may use enthalpies of 80–90 kJ/kg, whereas real weather data tends to be closer to 60 kJ/kg.
The result: oversized cooling coils and larger equipment, which lead to permanently higher investment and energy costs.
A similar situation arises with the design air volume: safety margins, benchmarks and redundancy concepts (e.g. n+1, 1+1) mean that systems are designed to be significantly larger than necessary.
Another example is the design of the treatment stages. Changes in conditions due to heat recovery are often not considered in subsequent registers.
This results in heating and cooling capacities that seem necessary in theory, but which are never actually utilised in practice.
The key is to ensure that safety is never compromised, while making targeted and realistic use of reserves.
Let us work together to design ventilation systems that are technically sound, economical and sustainable and that make sensible use of resources.
