Information

　　To make a successful refrigerated display cabinet, it is necessary to make full and reasonable use of the unique space; to complete the practical functions of the displayed products, to have a beautiful and novel appearance, attract attention, and give people a good impression; it meets the requirements of the merchant's CI. For the various display purposes of the refrigerator, the whole structure of the refrigerator also uses all detachable and assembleable parts, without any glue material, a screwdriver can complete the disassembly and assembly of the entire refrigerator, which is convenient for disassembly, assembly and transportation. Wait.

　　But mostly because the refrigerator has been used for a long time, the parts are aging or damaged, and the condensation in the refrigerator forms a loop, which causes the refrigerator to leak. In addition, the refrigerator causes the components to collide due to vibration during transportation. , The damage of the wire insulation layer may also cause leakage.

　　1. Leakage of the thermostat The phenomenon of leakage of the thermostat is: when a human hand touches the cabinet, there is hemp inductance, but the compressor runs and the temperature drop in the cabinet is normal. Because the thermostats of most island cabinets are installed on the inner wall, temperature changes in the cabinet will cause condensation around the thermostat. When the condensed water flows into the thermostat, the resistance value between the electrical contacts of the thermostat and the cabinet decreases and the cabinet becomes electrified. We can eliminate these problems by defrosting regularly, often erasing the water in the refrigerator, and preventing the condensate from flowing into the thermostat. At the same time, pay attention to frequently cleaning the bakelite frame of the thermostat and the surrounding dirt, because the dirt will also cause leakage when it absorbs moisture.

　　Of course, we still need to do a good job of maintenance of the single-air refrigerated cabinet frequently, so that there are fewer such problems and you can get the best benefits.

　　2. Moisture-proof wire leakage The fault of moisture-proof wire leakage is that after the power is turned on, the overload protection relay is frequently turned on and off, the compressor cannot be started, the cabinet is electrified, and there is hemp inductance when touched by hands. It is generally used in a refrigerator with a long service life. Is more common in. At this time, we can use insulating sleeves to cover the moisture-proof wire. It is best to remove the old wire and replace it with a new rubber insulated wire.

3. Compressor leakage. Compressor leakage faults are generally due to the long use time of the vertical wind cabinet around the island, which makes the insulation layer of the motor windings aging and falls off, resulting in leakage.

　　Check whether the insulation layer of the winding lead is damaged, causing the steel wire to be exposed and contact with the casing to cause leakage. If the above phenomenon exists, the damaged area can be wrapped with polyester film to avoid direct friction with the casing. If the insulation layer of the enameled wire is found to fall off, you should remove it and re-dip the paint or replace the motor.

　　4. After the induction leakage double-outlet refrigerator is started, if the cooling and control components in the cabinet are normal, but there is a feeling of numb electricity when touching the cabinet with your hands, it indicates that the refrigerator has induction leakage. The reason for this is generally that the control circuit of the compressor of the refrigerated cabinet and the lighting circuit in the refrigerated cabinet pass between the cabinet shell and the inner wall. If the wire insulation is aging, the refrigerated cabinet does not have a reliable grounding wire, and when the hand touches the cabinet When, it will produce hemp inductance. If you check that the neon bulb is bright with a test pen, it indicates that there is a serious induction leakage in the refrigerator.

What problems should be paid attention to when transforming a warehouse into a cold storage

In order to store fruits for a long time, many vendors have transformed their original warehouses into fruit fresh-keeping cold storages. However, there are still big differences between warehouses and cold storages. So what issues should be paid attention to when transforming warehouses into cold storages! 1. It is necessary to consider whether the thermal insulation structure of the original warehouse is suitable for cold storage and preservation. Generally, the exterior of the warehouse is made of polystyrene double-layer color steel plates or rock wool boards. This type of structure is not suitable for refrigeration, preservation, and quick-freezing. It is only suitable for storage at 15°C. If it is lower than 15°C ℃, it is recommended to add polyurethane double-sided color steel warehouse board of corresponding thickness in the warehouse. Generally, this kind of warehouse board has good heat preservation effect and high fire resistance level. 2. The bearing capacity of the steel structure at the top of the original warehouse needs to be considered. Some warehouse roofs use arc-shaped round pipe structures, which have limited force and cannot withstand large-area cold storage roofs. This is also the need to pay attention to the transformation. 3. Some warehouses are simple cement floors and are not suitable for reconstruction and construction of cold storage. Therefore, ground insulation treatment needs to be considered. If the temperature is below 0℃, the ventilation pipe must be pre-embedded to prevent the foundation from sinking due to the low temperature. In this way, the bottom material should be extruded board, air- and moisture-proof layer, concrete layer, etc., in short, moisture, water and heat preservation should be done. 4. Consider the carrying capacity of power equipment. Since it used to be an ordinary warehouse, the original power may not take into account the use of later equipment, so we also need to pay attention to power cables. Electricity for cold storage generally requires 380V commercial electricity. Maungsheng Refrigeration does not recommend using 220V for cold storage construction, even small fresh-keeping cold storage is not recommended. The specific cold storage construction uses 200V electricity or 380V electricity can see detailed analysis. 5. It is necessary to consider whether the warehouse can penetrate the wall hole, because the cold storage needs to be connected with the internal unit during installation to ensure its freezing effect. 6. The design of cold storage shelves also needs to consider other factors, such as: the selection of welding electrodes in the cold storage should correspond to the material and welding process requirements of the welding base material and ensure the welding quality of the welds. The characteristics of frosting in the cold storage should be considered, the weight gain should be appropriately considered when calculating the shelf selection, and the customer's refrigeration and defrosting process should be considered for the corrosion resistance of the structural spray coating.

Precautions for the use of cold storage

Cold storage refers to constant temperature storage air-conditioning equipment for food, dairy products, meat, aquatic products, chemicals, medicine, seedlings, scientific experiments, etc. In fact, the cold storage is very similar to the refrigerator, but the area of the cold storage is much larger than that of the refrigerator, and the temperature range is wider than that of the refrigerator. The ultra-low temperature freezing of the cold storage is not reachable by the refrigerator, but they have the same refrigeration principle. The following Lengdi Refrigeration will explain to you the precautions for using the cold storage! (1) Under normal circumstances, it is not recommended to manually control the temperature of the refrigeration switch to ensure the appropriate temperature for automatic operation; (2) Regularly check the operation control and temperature changes of the unit by the control cabinet,

The importance of cold storage design

Usually, customers will ask the cold storage engineering company to produce a detailed cold storage design plan in the initial stage of consulting the construction of the cold storage. Especially for large-scale cold storage, the design plan is the most important part of the entire cold storage construction process. Today, I will introduce to you the importance of cold storage design.
