Turn a fridge, designed to keep things cool/cold, off to allow it to cool down?
Yeah I maybe didnt explain it very well. Massive building, all the refrigeration is generated at the plant room with compressors outside, refrigerant is then pumped around d the building to local chillers (theres maybe 30 of them, each the size of a car).
The compressor motors (3 of them) are massive and have to rely on their own fans to keep cool, the compressor itself and motor are outside...baking in the sun. Motors are struggling to keep cool, the compressor discharge temps go up because of the high ambient heat...so the whole system shuts down.
I believe just the refrigeration system cost IRO £2 million, it could have been designed to cope with temps in excess of 34 c...but add cost, maybe another £ million ?
The company that maintain the equipment have 7 engineers in the UK. They're not always working of course but every single one was swamped with calls from almost all of their customers with plants struggling and shutting down with the temps, we were their best problem, most plants cant cope with 30 degrees, at least ours is specced at 34.
