The client’s old system in their filling hall was in poor condition, requiring a 100% fresh air system to eliminate the risk of cross-contamination.
The 10°C room temperature required for such an operation made this system potentially very expensive to purchase and operate, so part of our job was to make this as cost effective a project as we could.
We investigated a range of solutions for our client. Displacement air distribution was employed which reduced the total circulated air volume by 55%.
Heat recovery, or rather cold recovery, was employed between the exhaust and supply air streams, recovering 75% of the cooling effect from the exhaust air stream.
We also used an enthalpy wheel to maximise the efficiency of the heat recovery, and a molecular sieve wheel with a purge section and negative pressure design were employed to minimise the risk of cross-contamination.
A stainless steel construction was installed within the production area with supply air units. Together, all these improvements created a more efficient cooling environment.
