I have been asked to evaluate the possibility of replacing the evaporators in a pre-fab freezer walk-in room wich is about 12mx6mx8m. The truth is that the entire frame is moving, apparently due to the freezing of soil humidity underneath the reinforced concrete slab ( there is a topping+150mm of rigid polyurethane+vapor barrier+reinforced concrete slab). As the floor rises, so do the walls and roof, with the later one having already a crest right at the middle partition.
The evaporators are in really bad shape, although I cannot foresee much problem regarding the replacement of the units. What I`m really worried about is the possibility of worsening the current structural situation due to the stop, re-start, pull down and re-freeze of the frame. Any comments welcomed.
