With the development of the times refrigeration devices are becoming more and more common. All aspects of life are inseparable from its use. Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is important to select materials with good thermal insulation. Cold storage is a better material selection, and manufacturers need to grasp its key points in the production process of cold storage.Cold storage has strong stability. Polyurethane foam technology 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, the characteristics of the cold storage still do not separate and fall off from the carrier layer and remain stable under normal conditions.Larangelo,Pressure leak test: the pressure leak test of the fresh-keeping warehouse system is the same as that of the sewage blowing working sample, which is required to be carried out by air compressor. If ammonia compressor is used, the method of segmenting and reducing the pressure difference shall be adopted.Cold storage has good water tightness. Polyurethane rigid foam has low water absorption, good permeability to water vapor, disconnected and closed porosity of more than %. It is a dense microporous foam material, which is more dense than air surface and is not easy to permeate. It belongs to hydrophobic materials.Saltillo,However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.The refrigerant charge is insufficient. At this time, just add enough refrigerant.Watertight polyurethane rigid foam has low water absorption, good permeability to water vapor, and state of foam pores. It is not connected with each other, and the obturator rate is more than %. It is a dense microporous foam material, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material.

Insufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulation,LarangeloCold storage according to installation,As an important support for the development of cold chain performance, the standardized construction of cold storage refrigeration system is very important. It not only helps to rationalize the energy consumption of the cold storage system, but also has an important impact on improving the low-temperature preservation quality of commodities.The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time, or stops before the storage temperature reaches.Management DepartmentRequirements 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.Simple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage, so as to cool the refrigerant, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed, large total heat conduction temperature difference and complex system software, so it can only be used in less places, such as brine ice making and cold storage with constant temperature requirements.Large space rate of quick-frozen warehouse: for quick-frozen warehouses of the same size, reasonable design schemes store more goods than unreasonable ones. For the fixed size quick freezing warehouse, how to design it to maximize its space rate is often an important problem considered by our designers. In the design scheme of Lukang medical quick-frozen warehouse, we reasonably designed to expand the original storage capacity of boxes to boxes, which increases the space a lot.

Panel types of quick freezing warehouse: color plastic steel plate, salted steel plate, stainless steel plate, embossed aluminum, etc.Inspection basisThe drainage at the outlet of the cooling fan, the drainage of the volatile cooler and the road drainage of the refrigerated warehouse storing food or drinks shall not be immediately connected with the sewage and wastewater pipeline system software, an exhaust valve equipment shall be set in front of the main riser for flushing (thawing) water drainage.The air-conditioned storage is relatively fast. It usually reaches the required temperature, a few minutes faster and an hour slower. Of course,LarangeloFresh keeping cold storage installation manufacturer, according to the temperature of the environment, the amount of inventory and the temperature in winter and summer, refrigeration is also divided into air cooling,LarangeloInstallation of fruit and vegetable fresh-keeping cold storage, water cooling, direct cooling and simple cooling. Different refrigeration is fast and slow, but most small refrigerators are air-cooled, with guaranteed quality; Due to the high temperature requirements of the cold storage and the high degree of automation and regulation of the temperature, the temperature system of the cold storage adopts microcomputer full-automatic, does not need special people to operate, and can be remotely controlled. When the temperature exceeds the specified range, it will automatically alarm, which is of great significance to the proper preservation of the cold storage.Larangelo,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.The use of large-scale cold storage is naturally very strict in installation and material selection. Therefore, in the face of the above possible situations, we can strictly screen the insulation board materials of cold storage, which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board, so the details of the use environment should be considered for the wood making of many such products in the market.Strong deformation resistance, not easy to crack, smooth, stable and safe. Polyurethane material has stable porosity structure and basically closed pore structure. It not only has excellent thermal insulation performance, the life expectancy of rigid foam polyurethane insulation can reach more than years. During the structural life period, it can reach the unit price of dry, wet or electric corrosion under normal service conditions, while the unit price of insect, fungus or algae foam material is higher than other traditional insulation materials, but heating will increase the cost and the cooling cost will be greatly reduced.
