Heat Reclamation

[Davidd]

I have a refrigerator that is 3300 sq ft. I have designed hydronic system for frost protection system that requires 5 btu/sq ft. There is 3/4" PEX tubing used at 24" OC

I have been asked how to pipe and collect the heat off the compressor and use it for the frost protection.

I assumed there would be some sort of heat reclamation tank that could be used. I am concerned that the frost protection system would not use enough heat off the compressor. I am trying to find out more information on the compressor. Freezer is going to be at -4F.

Has anyone seen a product used for this? If so what is the name of the product

Has anyoned designed something like this? If so can you point me in the right direction

Thanks

Is it not cost effective to use a hot gas defrost?

Is it not cost effective to use a hot gas defrost?He is not trying to defrost the evaporator but provide an anti-freeze circuit to the structure.
