An Article Tells You How To Prevent Cold Bridges During The Construction of Cold Storage!

In the design and construction process of cold storage, a frequently mentioned but easily overlooked issue is the "cold bridge". If the cold bridge phenomenon is not prevented, it will lead to the loss of cold energy, an increase in energy consumption, and may even affect the thermal insulation effect of the cold storage and the quality of stored items. The professional engineer team of Fland will tell you in an article how to prevent cold bridges during the construction of cold storage!

                                                                                                Why does a cold bridge occur?

First, let's take a look at what a "cold bridge" is. A cold bridge refers to the phenomenon where the heat transfer coefficient of certain parts in a building is significantly higher than that of other parts, causing heat to be concentrated in that area and forming a local low-temperature zone.

The main causes of cold Bridges in cold storage are as follows: 

1. Unreasonable structural design: For instance, improper design at component connection points, corners and other parts leads to easy heat transfer. 2. Differences in thermal conductivity among different materials: The thermal conductivity of different materials varies, and cold Bridges are prone to form at the junctions. 3. Construction quality issues: Non-standard construction, such as loose insulation layer splicing and improper handling of fasteners, etc. 4. Thermal bridge effect: In buildings, areas with dense heat flow and lower inner surface temperatures are prone to the formation of cold Bridges. 5. Environmental factors: Changes in external temperature, humidity, etc. may also lead to the formation of cold Bridges

                                                                                                         Where can cold Bridges occur

In cold storage, cold Bridges usually occur at the junctions of walls, roofs, floors and insulation materials, or in areas where they are formed due to the high thermal conductivity of component materials.

The main locations of cold Bridges in cold storage are usually as follows: 

1. The junction of wall panels and the ground 2. 3. Junctions of wall panels and ceiling panels, edges of air inlets and outlets, door openings, etc. 4. Joints of different insulation materials. 5. Protruding structures such as columns and beams

                                                                                                                        What are the hazards of cold bridges?

1. Increased energy consumption: Cold Bridges can lead to heat transfer, causing the refrigeration system of cold storage to consume more energy to maintain low temperatures and increase operating costs. 2. Affect temperature stability: Disrupt the uniformity of temperature inside the cold storage, causing significant temperature fluctuations in certain areas, which is not conducive to the storage of items. 3. Condensation and icing: Condensation and even icing are prone to occur at the cold bridge area, which may damage the goods and affect the normal use of the cold storage.4. Shortening the lifespan of cold storage: Long-term exposure to cold Bridges will accelerate the damage of the cold storage structure and insulation materials, thereby reducing the overall service life of the cold storage. 5. Reduce refrigeration efficiency: It leads to a decline in the refrigeration effect of the cold storage and fails to effectively maintain a low-temperature environment. Therefore, when building a cold storage, a series of measures must be taken to prevent the occurrence of cold Bridges.

   
   

                                                                                                           How to avoid cold Bridges

First of all, insulation materials with low thermal conductivity and good heat preservation performance should be selected, and it is necessary to ensure that the connection between the insulation materials is tight and seamless. Secondly, effective insulation measures should be set up at the junctions of walls, roofs, etc., such as installing insulation layers and using insulation materials.

In addition, the occurrence of cold Bridges can be reduced by optimizing the structural design of cold storage and enhancing the insulation performance of components.

Fland reminds you: Once a cold bridge phenomenon is detected, please handle and repair it in a timely manner to prevent the problem from further expanding and affecting the normal operation of the cold storage.
