Why Is It Necessary To Design The Insulation Layer for Cold Storage Floors? It's Extremely Important; You Must Read This To The End!

Why is it necessary to design the floor insulation layer of a cold storage?

Many people often neglect the design of the insulation layer of the cold storage floor during the construction process. The professional technical team of Fland answers for you: Why is it necessary to design the insulation layer for the floor of a small cold storage? Because the temperature inside the cold storage is low, heat is transferred from the outside to the cold room through the ground. This part of the incoming heat becomes the ground load of the cold storage refrigeration system and needs to be eliminated by the refrigeration system. By setting up a reasonable insulation layer and floor structure, the ground load can be effectively reduced, thereby lowering the cost of refrigeration equipment and operation management.

For cold storage facilities with a temperature of 0℃ or below, although the floor is equipped with an insulation layer, it cannot completely prevent heat transfer. If the soil layer beneath the ground is not replenished with heat, the temperature of the soil layer will gradually drop below 0℃, causing the water in the soil layer to condense into ice. Moreover, due to the temperature difference between the upper and lower layers and the presence of ice crystals, the partial pressure difference of water vapor between the upper and lower layers of the soil causes the water vapor in the lower layer of the soil to continuously move to the upper layer, resulting in the gradual expansion and enlargement of the ice, which is most likely to cause the ground or foundation to freeze and swell, endangering the structural safety of the cold storage. Therefore, for cold storage facilities with temperatures below 0℃, in addition to insulation layers and moisture-proof measures, the floor design should also take anti-freezing and anti-swelling measures. In conclusion, the floor of a cold storage has high requirements for temperature insulation and moisture-proof performance. It is essential to design the insulation layer of the cold storage floor.

What are the benefits of a rational design of the insulation layer for cold storage floors?

01The main function of the insulation layer that maintains the low-temperature environment

 inside the cold storage is to reduce the heat exchange between the inside and outside of the cold storage, thereby keeping the low-temperature environment inside the cold storage. This is crucial for storing goods that require low-temperature preservation or freezing.  

02 Energy conservation and electricity saving

Through effective insulation layer design, the energy consumption during the operation of cold storage can be reduced, the load on refrigeration equipment can be lowered, and thus energy and operating costs can be saved. 

03   Protect the floor structure                                                        

In cold storage environments, the floor structure is prone to be affected by low temperatures and humidity, leading to structural damage or performance degradation. The insulation layer can isolate the adverse effects of the external environment on the floor, protecting the integrity and stability of the floor. 

04 Prevent Condensation and dampness

The low-temperature and high-humidity environment inside cold storage can easily cause condensation and dampness on the floor surface, thereby affecting the storage quality of goods. The insulation layer can effectively prevent the occurrence of condensation and moisture problems.

05Comply with design specifications and standards

 The design and construction of cold storage facilities must comply with relevant norms and standards, including requirements for the insulation layer of the floor. A reasonable insulation layer design can ensure that the overall performance and safety of the cold storage comply with the regulations. 

06Easy to clean and maintain

A reasonable insulation layer design can also take into account future cleaning and maintenance work. For instance, materials that are easy to clean and maintain can be chosen, and reasonable access ports and passages can be designed.
