The polyurethane insulation board used in the construction of cold storage shall be integral and continuous, and there shall be no joint in the middle. The junction of polyurethane insulation board, top plate and ground shall be made into fillet arc for transition, and if bubbles are generated, it indicates that the refrigerant is leaking). And ask the combined cold storage engineering personnel to supplement the refrigerant and deal with the leakage. Check whether the sealing of the combined cold storage door is intact and eliminate it. Whether the refrigerator of the combined cold storage works. Whether the parameter setting of the computer controller of the cold storage is correct and reassemble the cold storage door for installation. Check whether the cooler in the cold storage fails and replace it. Whether there is enough clearance for stacking articles in the warehouse and dredge them.
Edmonton.Regularly maintain whether the connecting pipes on the connecting pipes and valves of the refrigeration unit are firm and whether there is refrigerant leakage. The way of leak detection is to use sponge or thin cloth with detergent, foam, and then evenly coated in the area to be leaked, and observe for a few minutes. If water leaks, bubbles will appear. Mark the leaking area, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.
.The foundation of cold storage is affected by low temperature, and the water in the soil is easy to be frozen. Due to the volume of frozen soil, the ground will be broken and the whole building structure will be deformed. If the damage is serious, it may even make the cold storage unusable. Therefore, in addition to the thermal insulation layer, the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore, the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment, especially in the process of periodic freezing and thawing cycle, building structures are vulnerable to. Therefore, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.
Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level, it is impossible to deal with it, salted steel plate, stainless steel plate embossed aluminum, etc.
For cold storage, it is very common in our production and life. Cold storage is very important for food freezing and preservation but its energy consumption is very large in the use of cold storage. How can we solve this problem?
If the controlled atmosphere storage is not used for a long time, does it also require refrigeration? If the controlled atmosphere storage is not used for a long time after installation, it does not need refrigeration operation as long as it does not show fluorine leakage. However there may be fluorine leakage due to long-term non use, so refrigeration operation should be carried out at this time.
In the cold storage project, the selection of cold storage is related to the overall operation of cold storage in the future. The selection of high-quality cold storage is conducive to the use and maintenance of cold storage. This requires us to inquire more about the warehouse board for cold storage engineering. Before the construction of cold storage project, we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature, attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.
Application process.Stretch perlite: stretch perlite is a kind of granular material with porous layout. The gap in it blocks out the heat. Professional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage, strict testing, the water vapor in the cold storage is easy to condense, and the water absorption of extensional perlite is particularly strong. If it absorbs a lot of water, its nature will be greatly reduced. Therefore, it is necessary to be careful to select extensional perlite as cold storage.
The wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.
Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35 ~ 40kg / m3, the thermal conductivity is only 0.018 ~ 0.024w / (m.k), which is the lowest among all thermal insulation materials at present.
Clean and professional cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage have stable performance, safety, reliability and maintenance free. The technical level has reached the domestic level and the advanced level of similar international products. If there is a large amount of ice and water, it must be cleaned in time, and it must not be knocked during cleaning, so as not to damage the ground and affect the service life of the cold storage.
Information recommendation.The water tank is designed to be separated from the machine body and is double-layer. It will not drip due to condensation caused by internal and external temperature difference. It can be interlocked with the refrigeration system, that is, it will not be humidified during refrigeration to prevent serious frosting of the fan.
The customer specifies the refrigeration and conversion conditions required by the customer, the temperature of refrigeration and refrigerant, and the provisions of the customer's application site and application installation level.
Requirements for refrigeration equipment in quick freezing warehouse: the strict sealing of quick freezing warehouse is obviously different from that of ordinary quick freezing warehouse. Therefore, how to seal the refrigeration equipment is the key. First of all, all through wall pipelines must be equipped with sleeves, the frost flushing water return pipeline must be equipped with U-shaped bend water seal, and the main frost flushing and return pipeline outside the warehouse shall be equipped with air filling port to prevent the gas in the warehouse from being pumped out of the warehouse by negative pressure. In addition, due to the good sealing of the quick freezing warehouse, the set fluctuation range of the warehouse temperature should not be too large to prevent excessive positive and negative pressure from damaging the warehouse body.
Edmonton.The door of the combined cold storage is not tightly closed. Please adjust the distance between the hinge on the door and the door lock and the storage body.
The physical properties of polyurethane insulation board are relatively good, which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.
Floor insulation of small cold storage the structure of small cold storage is usually called surface, that is, the top, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, loading and unloading, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.
