Now many vendors in order to be able to store fruit for a long time, the original warehouse into fruit preservation cold storage, but there is still a big difference between the warehouse and the cold storage, then the warehouse into the cold storage need to pay attention to what problems!

1. It is necessary to consider whether the thermal insulation structure of the original warehouse is suitable for refrigeration, preservation and other conditions. The general warehouse is used outside the polystyrene double color steel plate or rock wool board and other structural forms, this is not suitable for transformation into cold storage, fresh-keeping, quick-freezing cold storage, only suitable for 15°C storage environment, if less than 15°C, it is recommended to add the corresponding thickness of polyurethane double-sided color steel library board, generally this library board insulation effect is good, high fire rating.

2. The bearing capacity of the steel structure at the top of the original bin needs to be considered. Some warehouses use curved round pipe structure, the force is limited, can not withstand a large area of cold storage roof, but also need to pay attention to the transformation.

3, some warehouses are simple cement floor, but also not suitable for the construction of cold storage, need to consider the ground thermal insulation treatment. Below 0 ° C, the ventilation pipe must be embedded to prevent the foundation from sinking because of low temperature, so that the bottom material should be selected extruded board, gas insulation moisture barrier, concrete layer, etc., in short, do a good job of moisture, water and insulation.

4. Consider the bearing capacity of power equipment. Since it was once an ordinary warehouse, the original power may not have taken into account the use of later equipment, so we also need to pay attention to power cables. Cold storage electricity generally requires 380V commercial electricity, Maung Sheng refrigeration is not recommended to use 220V electricity for cold storage construction, even small fresh cold storage is not recommended. Whether the specific cold storage construction uses 200V electricity or 380V electricity can be analyzed in detail.

5, it is necessary to consider whether the warehouse can punch through the wall hole, because the cold storage needs to be connected to the external unit and the internal unit during installation to ensure its freezing effect.

6, cold storage shelf design also need to consider other factors, such as: the selection of welding rods in the cold storage, need to correspond to the welding base material and welding process requirements, and ensure the quality of weld welding. The characteristics of frost formation in the cold storage should be considered, the weight gain should be properly considered when calculating the selection of shelves, and the corrosion resistance requirements of the customer's refrigeration and defrosting process for the structural spray layer should be considered
