Refrigerating units of provision storerooms for storage of sausage, ham products and edible animal fats

Section 3

Cooling chambers. Basic dimensions and construction

Cooling chambers with the same dimensional and heat insulation characteristics (see Table 3.1) were selected in design of refrigerating unit for sausage, ham products and fats storing.

Modular demountable constructions from Polair sandwich panels, intended for maintaining the temperature that refrigerating machines create inside the chambers, were applied as cooling chambers. These cooling chambers consist of sandwich panels (wall, ceiling and floor panels), door block and corner posts.

Wing doors are equipped with a handle with built-in lock which is locked from outside and has a device for emergency opening from inside.
