Nowadays, many businesses choose to build cold storage to preserve goods, especially food. Panels are an indispensable component in these cold storages. So cold storage panel What is it, what are its uses and what types are there? Let's Tan Long Discover details about this type of panel in the article below.
What is cold storage panel?
Panels are specialized materials with effective heat insulation and fire resistance, often used in cold storageThese panels are tightly bonded together to ensure that cold air does not escape, while preventing moisture and outside air from entering, helping to protect goods in the warehouse from damage.
Structure of cold storage panel parts
Cold storage panel has a simple structure, consisting of two main parts:
- Outer shell: The two sides of the shell are usually made of stainless steel or powder-coated steel, protecting the insulation layer inside.
- Insulation core: The core is made of foam material, injected into the panel shell. This foam material is lightweight, insulates effectively and does not crack when shaken.
Classification of cold storage insulation panels
PU panel
PU panel has an insulation core made of Polyurethane, with a thickness of 50 - 200mm. The outer shell uses cold-rolled steel with a thickness of 0.35 - 0.6mm. This panel has excellent sound and heat insulation thanks to its low thermal conductivity and zigzag sound structure when meeting the panel. Depending on your needs, you can choose the appropriate thickness. For example, for cold storage below minus 10 degrees, you should choose a 100mm thick panel to ensure heat retention.
EPS panel
EPS panels also have an outer shell made of 0.35 - 0.6mm thick galvanized steel like PU panels, but the insulation core is EPS foam (Expanded Polystyrene). EPS foam has superior insulation and fire resistance. These layers of materials are firmly bonded with glue. EPS panels have many different densities from 8 - 14kg/m3, suitable for many types of projects such as small cold storage walls, operating rooms, and labs.
PIR panel
PIR panels have fire resistance that meets B1 standards according to European DIN 4102 standards. The structure of the PIR panel includes color-coated cold-rolled steel and a thick PIR foam insulation layer. The production technology does not contain HCFC, is environmentally friendly, and does not affect the ozone layer. This type of panel is often used to construct clean rooms, cold storage and cool storage.
Stainless steel cold storage panel
Stainless steel panels have an outer shell made of 304 stainless steel, meeting food safety and hygiene standards. The inner insulation core is foam. This type of panel is often used in cold storage below 20 degrees Celsius, preserving food, vaccines, drugs, etc. The characteristic of stainless steel panels is to ensure high hygiene, but the price is quite high so it is often used for small cold storages.
Uses of cold storage insulation panels
Cold storage panel With many outstanding features, widely applied in many fields, typically:
- Moisture-proof and heat-insulating: Thanks to this ability, cold storage panel Often used as partitions for warehouses and ice cellars, helping to maintain temperature and protect goods from moisture.
- Antibacterial and safe for health: Antibacterial and safe panels are used in pharmaceutical rooms and operating rooms, ensuring a clean and safe environment.
- Good sound insulation: Not only insulation, cold storage panel also has excellent sound insulation, suitable for projects requiring quietness such as theaters, recording studios, and television stations.
- Applications in civil works: Insulated and soundproof panels are also widely used in houses, offices, shops, spas, bringing a comfortable and quiet space.
- Application in high-end projects: With high durability and reasonable price, insulated panels are the priority choice for high-end projects such as hotels and villas.
Standard cold storage panel installation process at Tan Long
Before starting to install cold storage, it is necessary to fully prepare the following materials and tools: Quantity cold storage panel suitable for the area to be installed, cold storage doors, components for ceiling frame systems, detailed designs of cold storage, auxiliary tools such as screws, cle, and other tools.
Check the flatness of the cold storage
The cold storage floor must be checked for flatness, a water level can be used to do this. The installation surface must ensure a slope of 2 - 3%. If the slope exceeds this level, it must be adjusted accordingly to ensure safety during use and avoid water stagnation after a period of time.
Cold storage shell installation
After leveling the installation surface, assemble the panels together to build the outer wall. It is necessary to create a frame from horizontal bars, vertical bars or U-shaped bars. These support bars will be assembled into a frame and firmly screwed to fix the panels.
Install ceiling panel system
Panel ceilings are often used for cold storages longer than 4m. First, weld the panels together according to the beam frame structure. Check the welding points again to ensure they are secure. Next, determine the hook hanging position according to the original design drawing. The installation of the panel ceiling system must ensure a firm connection between the panels at the following points: wall - ceiling, wall - wall, wall - floor.
Currently, construction units often use PU panels for deep cold storage and EPS panels for above-ground storage.
Cold storage panel door installation
After installing the cold storage walls and ceiling, the project is completed 70%. Next, install cold storage door according to the design. You should choose doors made from panels to ensure soundproofing and insulation.
Check and complete cold storage project
When the door installation is complete, proceed to accept the project. Check the joints between the panels and door hinge Check to make sure it is secure. If there is a gap, use silicone glue to seal it. Reinforce the joints if there are signs of looseness. Install additional accessories such as gauges, pressure valves and bell switches. Test the refrigeration system to check if cold air is leaking out. After the acceptance test meets the standards, the cold storage can be put into use.
Instructions on how to preserve cold storage panels well
To ensure the plate cold storage panel To always be durable and operate effectively, the following maintenance principles must be followed:
- Avoid exposure to high temperatures: Do not let the cold storage PU panel come into direct contact with high heat sources to avoid damaging the insulation layer and reducing the lifespan of the panel.
- Ground isolation: Store panels by placing them on shelves or insulated surfaces, avoiding direct contact with the ground to prevent mold and insect infestation.
- Do not place heavy objects on the panel surface: Avoid placing large objects on the panel surface to avoid deformation or damage to the panel structure.
- Isolate from low pressure areas: Keep the panel in a place with stable pressure, avoid low pressure areas to maintain the insulation and durability of the panel.
- Keep away from flammable materials: Store the panel away from flammable materials to ensure safety and prevent the risk of fire or explosion that could damage the panel.
Notes when using and constructing cold storage panels
For use and construction cold storage panel effective, the following issues should be noted:
Cold storage floor surface must be flat
An important factor when constructing a cold storage using panels is that the floor surface must be flat. A flat floor surface helps the installation of the insulation panel go smoothly and ensures the quality of the load-bearing capacity. Construction on a rough surface not only takes time but also affects the quality of the construction and can easily cause water stagnation, making it unhygienic after a period of use.
Cold storage must be absolutely sealed.
Goods in cold storage need to be stored at temperature stable below 10 degrees Celsius. Leakage in cold storage not only reduces cooling efficiency but also consumes a lot of electricity. Therefore, during the installation of panels, care must be taken to avoid creating gaps. Regularly check and maintain cold storage to detect and promptly handle damage.
Notes when installing refrigeration systems and lines
When installing a refrigeration system, choose a location that ensures that the cold air can spread evenly throughout the warehouse space. The refrigeration system must have a capacity suitable for the warehouse area. Electrical wires must be routed underground to avoid electrical interference due to humidity and to protect against damage due to prolonged exposure to low temperatures.
Door system must have rubber gasket
Although the door is sealed, there is still a possibility of cold air loss. To minimize this situation, it is necessary to equip the door with rubber gaskets to ensure tightness.
Regular inspection, maintenance and servicing
Equipment and components in cold storage will gradually deteriorate after a period of use. It is necessary to hire a maintenance team to periodically check and replace equipment. Plan cleaning to ensure a clean environment, avoid damage and contamination of stored products.
