The joy of sunny weather in summer comes alongside rising temperatures inside warehouses. As heating and cooling experts, we supply warehouse cooling solutions for a variety of commercial properties – including warehouses. If you’re wondering how to cool a warehouse in summer, read on.

Evaporative cooling

As warehouse cooling systems go, evaporative cooling is a strong contender for the number one spot. Here’s a run-down of some of the top reasons evaporative cooling is a great answer to the question: how do I cool a large warehouse?

1.      Efficient and energy saving

Using a warehouse cooling system can impact your business’s carbon footprint. However, evaporative cooling is a superbly energy efficient solution – using around 90% less energy than many other warehouse cooling solutions.

This energy efficiency doesn’t just help save the environment – it saves you money on your energy bill too.

2.      Door and windows can be kept open

Unlike other cooling systems, evaporative cooling continues to be effective even when doors and windows are open – which is a common occurrence in busy warehouses, where bay doors are often kept open for loading.

When the hot weather hits, it’s also nice to have the option to throw open doors and windows and let some fresh air into your warehouse. With evaporative cooling, you can keep your building cool and prevent it from getting stuffy by opening doors and windows.

3.      Easier and cheaper maintenance

Evaporative cooling units are built to last. They also have fewer moving parts, making them simpler and cheaper to maintain than older, more complex warehouse cooling systems.

Employing heating and cooling experts, like Heritage, to conduct regular maintenance on your evaporative cooling system will keep issues down to a minimum, and ensure your system is running at optimum levels.

4.      Better internal air quality

Evaporative cooling can actually help reduce the spread of viruses in your warehouse. This is because the system draws fresh air in from outside of the building. This ensures the air inside your warehouse is continually refreshed, rather than recirculating stale air.

Not only does this reduce the risk of disease spreading in your warehouse, it will help people with allergies and respiratory problems.

Air conditioning

Air conditioning has been a tried and tested warehouse cooling solution for many years. There are a few reasons why air conditioning has historically been the go-to choice.

1.      Consistent internal temperature

Keeping up with the ever-changing weather of the British summer can be hard going. By installing commercial air conditioning to your warehouse, you can maintain a constant internal temperature – no matter what the weather is doing.

When the hot weather finally arrives, being able to keep your warehouse cool using air conditioning will make things much more comfortable for hardworking staff.

2.      Removes dust and pollen

When air conditioning units draw in air, it passes through a filter that catches dust and pollen – helping to improve the air quality inside your building.

It’s important to remember that if your air conditioning’s filters become clogged with dust they could in fact negatively impact the air quality of your building. Make sure your air conditioning unit is well maintained and change the filters regularly.

3.      Ducted air conditioning

There are several benefits to having ducted air conditioning systems in warehouses, including:

  • Noise levels: Ducted air conditioning runs very quietly in the background.
  • Heating and cooling: Most modern ducted air conditioning systems are able to both heat and cool.
  • Quick: When temperatures rise, you don’t want to wait hours for your warehouse to cool down. Ducted air conditioning works quickly to bring internal temperatures down to a comfortable level.
