Hi,

I'm new to this forum and not a refrigeration engineer but would like to ask a question which I suspect hasn't got a simple answer!

A warehouse is used to store food at a cooled temperature of 10 degrees C and the electricity consumption for refrigeration is 900,000kWhrs per year. The height of the building is twice that it needs to be and so approximately half the volume of the building is unecessarily chilled. If a false ceiling was introduced the volume of cooling could be halved.

Would it be fair to say the energy consumption to chill this area could be half?

Is there a formula or rule of thumb calculation that can be used to work out the typical energy requirement of the scenario I've described?

Thanks
