NaranjoGeneralWe must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, because a large number of items need to be insulated so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse and the penetration of the envelope is carried out from outside to inside all year round. R11 gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.
No matter whether the food cold storage or quick-frozen storage is in use it is inevitable that there will be various small faults. Don't be nervous when there are problems. You can find or eliminate problems according to the knowledge taught today.
Vancouver.The knowledge of cold storage repair and maintenance is something you can't fail to understand in the process of daily use of cold water!
The spacing of pull rivets at inner and outer corners is 300mm and 200mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.
.Emergency measures during the use of the medical cold storage project, it may also encounter power failure or power failure. In fact, most medical cold storage projects will be equipped with emergency equipment so that the medical cold storage project can achieve the effect of normal power supply. Once the automatic temperature or humidity monitoring system is abnormal, the cold storage door should be closed in time, So as not to expose more air conditioners, resulting in corresponding problems in the quality of stored products. The medical cold storage project also has a self rescue system in time. If the temperature of the cold storage exceeds the limit, the system cooling system will also be turned on. When the temperature returns to normal, it will be automatically turned off.
Install the library body. Generally, the warehouse body can be divided into small warehouse body and large warehouse body. The small warehouse body is basically a combined cold storage assembled with warehouse plate. The large warehouse body is mostly a civil cold storage. The assembled or constructed warehouse body is generally required to be flat, compact and solid, without hollow feeling, load-bearing, antifreeze, moisture-proof, etc.
However, so reasonable maintenance is particularly important.
Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment, use the volatilization of the refrigerant to immediately cool the air in the air,VancouverHow much is it to install a small cold storage, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed, small heat conduction temperature difference and simple system software, so it is widely used.
The selection of wires shall have a safety factor, and the temperature of the wire surface shall not exceed 40 ℃ during unit operation or defrosting.
The exhaust temperature of the compressor equipment is often. When the season changes and the temperature difference changes greatly, pay attention to it. If the machine is abnormal, food cold storage is a systematic project of artificial refrigeration to ensure food quality and reduce food decay in a low-temperature environment. Refrigeration technology affects the design of food cold storage, meets the needs of refrigeration technology, convenient production, energy saving and cost reduction. What problems should be considered in the construction of food cold storage?
The average service life of rigid polyurethane insulation structure with stable quality, long service life and high comprehensive cost performance can reach more than 30 years under normal use and maintenance conditions. Under the normal service conditions during the service life of the structure, it will not be affected by drying, or electrochemical corrosion, as well as the growth of insects, fungi or algae or rodents.
The medical cold storage has been widely used in the industry. For the use of the medical cold storage project, we must combine the performance of the product and store it according to the temperature and humidity required by the product. The automatic temperature box also needs to be used outside the product cold storage. At the same time,VancouverCold storage board installation design, the management personnel must be familiar with the operation steps of the medical cold storage project.
Able to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall, such as the sudden shower after a long time of exposure, or shading during exposure, will not cause damage to the surface of the cold storage.
device management.The foaming technology of polyurethane with strong stability makes it have superior bonding performance. The firm combination of polyurethane rigid foam and carrier layer is the basic premise to ensure the stability of external insulation layer. That is, under the unfavorable local temperature and humidity conditions, it can bear various internal and external combined loads such as wind force, self weight and normal collision, and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.
With the continuous development of cold chain industry the construction scale of logistics cold storage is expanding, and the construction quantity is also increasing. According to statistics, at present, the performance growth rate of cold chain is maintained at 8% ~ 10%; This leads to the increasing demand for logistics cold storage. In the design of logistics cold storage, people have strengthened the optimization and transformation of the existing cold storage on the basis of the design and construction of the new cold storage, refrigeration, insurance and so on.
When opening and drilling is required for the top warehouse plate or wall plate, the internal and external setting out and positioning shall be carried out according to the drawing design requirements, and the opening and drilling shall be carried out after review; The inlet hole, liquid inlet hole, return hole, water supply hole and drainage hole shall be opened with a hole opener. Construction treatment shall be carried out in time after opening and drilling, and the orifice shall be closed with foaming material or sealant to prevent air leakage and cold running; The door, vent and delivery port shall be decorated with wrapped edges and fixed with pull rivets, with a spacing of 300mm and 150mm outside.
Vancouver.Judge the operating sound of the compressor, and carefully listen to the operating sound of water pump, cooling tower, compressor, fan and other equipment. In case of abnormal sound, timely warranty is required, so as to avoid greater damage to the compressor due to untimely warranty.
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.
There are many kinds of cold storage. According to the material, stainless steel plate and salted steel. Among them, color steel plate has strong anti rust ability, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, it is divided into flat plate and wave plate. The former is flat after the surface material is formed, and the latter is rugged after the surface material is formed. According to the thickness and color of surface materials, the thickness of stainless steel is 0.5mm and 0mm, without color requirements; The thickness of salted steel plate is 0.5mm, without color requirements; The thickness of PE paint baking board is 0.5mm, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the 150 mm storage plate is 150 mm, and the thickness of the vertical plate is 160 mm and 100 mm, which is suitable for the insulation conditions of - 25 ℃ ~ - 45 ℃; 100mm storage plate: the thickness of the ceiling plate is 100mm and the thickness of the vertical plate is 110mm, which is suitable for the thermal insulation conditions of 0 ℃ ~ - 25 ℃. The thickness of the ceiling plate and the vertical plate of 60mm storage plate is 60mm,VancouverQuotation for medical cold storage installation, which is suitable for the thermal insulation conditions above 0 ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, including standard plate vertical plate width wa = 900mm heaven and earth plate width WB = 980mm, vertical angle plate W1 = 790mm, W2 = 840mm, W3 = 740mm and W4 = 880. The dimensions of non-standard plates are different from those of Wa, WB and W4.
