Excess Heat Generation

delaney001

Hi,

Some details:
Work in a plant that creates a huge amount of heat and we have no way of using it. The plant is 900Sqm foot print with about 3200 cubic metres enclosed. We never see a temperature lower than 25C in the building. It is a basic warehouse unit with corrugated sheeting on the roof, blocks on the flat for walls, concrete floors. No insulation.
Our process requires no large amount of water or heat, its all electrical. The heat is generated via the electrical machines.

The problem:
We are in the process of adding a few more machines, and the temperature within the building is creeping up with each new machine added. We have an extractor fan running off a temperature probe, set to come on at 25C. The building has four mesh inlets about 1m squared each (2 on 2 walls). The fan pulls cool air in through these and out through the fan, cooling the building back down to 22C or so. Fan turns off and the temperature creeps back up, rinse, repeat.

It feels criminal to just pump heat out the window without using it. But without any requirement for hot water on site, is there any point in putting in some sort of heat transfer/exchange unit? Or is there a way of cooling our building without having to install a large volume air handling unit?

Any advice welcome.

Are there any offices on site that require heat or neighbouring buildings.

Not really, nothing on a large scale. If there was what would you suggest?

You can use any cooling system you install to transfer the heat to water and transfer it to different areas. It can be used by yourself or neighbouring buildings for heating and hot water. You could even commodity and sell it.

I assume there are very large costs for installation?

Use the heat to boil the oil, open a chipper, bobs your fathers sibling

Can you recommend a type to me to research? This isn't my area of work but we have a very small team in work. And I don't think I can look at another extractor being put in to pump heat out the window. Feels criminal.

Difficult to research. Normally the system is adapted to suit the situation. Firstly decide where the excess heat could go and then go from there. If you want to pm me details ill make a few suggestions and point you in the right direction.

I'll take you up on that offer. Thanks

Trigeneration, cool the building instead of heating it.

Op I’ve worked in similar places and my go to answer install a jacuzzi and hot tub on the roof

You need to be burning vast amounts of gas for trigeneration to work and creating vast amounts of heat at the same time but at least it sounds cool.
