Direct evaporative cooling (DEC) can be an excellent option for large workspaces in the UK for several reasons:

1. Energy Efficiency & Cost Savings

• DEC uses the natural process of water evaporation to cool the air, consuming up to 80–90% less energy than traditional air conditioning.

• For large industrial or commercial spaces, this translates into significant operating cost reductions, especially where cooling demand is seasonal rather than constant.

2. Fresh Air Supply & Improved Air Quality

• Unlike recirculating systems, DEC continually draws in outside air, cools it through evaporation, and pushes it into the building.

• This results in a constant supply of fresh, filtered air, helping reduce the buildup of CO₂, odours, and pollutants—ideal for warehouses, workshops, and factories.

3. Suited to UK Climate

• DEC works best in moderate and dry conditions, and the UK typically has warm but not overly humid summers.

• Even on days with 50–60% relative humidity, DEC units can still provide a noticeable temperature drop, making workspaces far more comfortable.

4. Scalability for Large Spaces

• Traditional refrigerant-based air conditioning becomes costly and inefficient in very large or open environments (e.g., warehouses, production halls).

• DEC units are relatively low-cost to install and scale up, making them practical for covering big floor areas.

5. Sustainability & Green Credentials

• With no refrigerants and minimal electricity usage, DEC systems have a low carbon footprint.

• For UK businesses aiming to improve their ESG profile or meet sustainability targets, DEC can be a strong selling point.

6. Comfort Without Overcooling

• Instead of creating an artificial “chill,” DEC provides natural-feeling cooling, reducing the risk of employees experiencing temperature extremes.

• This makes it particularly suitable for environments where doors and shutters are frequently opened (e.g., logistics hubs).

 

✅ In short: Direct evaporative cooling is ideal for UK large workspaces because it’s energy-efficient, low-cost, provides continuous fresh air, suits the UK’s moderate climate, and aligns with sustainability goals.
