Indirect cooling is that the air in the warehouse is pumped into the air cooling device by the blower. The air is absorbed by the evaporation pipe circling in the cooling device, and then sent to the warehouse for cooling. The advantages of air cooling are rapid cooling, uniform temperature in the warehouse, and can bring harmful gases such as carbon oxide out of the warehouse during storage.Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, the top and wall are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, while the ground needs to be insulated separately. At present the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.Milheim,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!For water-cooled units,MilheimLarge cold storage installation company, the turbidity of cooling water shall be frequently, the cooling water shall be replaced frequently, emitting,MilheimMedicine fresh-keeping cold storage, dripping,Refrigeration system: refrigeration system is the core part of cold storage design. It is the key to determine the economy environmental protection and performance 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.Goods are imported and exported frequently and the throughput is large according to the requirements of production and operation
Insufficient refrigeration dose and capacity in the system: there are two main reasons for insufficient refrigerant circulationThe suction pressure of fresh-keeping storehouse remains unchanged, and when the exhaust pressure increases, when the suction pressure decreases, the exhaust temperature also increases. Both cases are caused by the increase of compression ratio of fresh-keeping warehouse. Too high condensation temperature and exhaust temperature of fresh-keeping warehouse are unfavorable to the operation of compressor, which should be prevented. Too high exhaust temperature will dilute the oil and even carbonize and coke, which will worsen the compressor conditions of the fresh-keeping warehouse. - precautions for vertical plate of cold storage: vertical plate displaytarget,Airtight construction of quick freezing storehouse: the modified atmosphere fresh-keeping storehouse is developed on the basis of the traditional high-temperature fresh-keeping storehouse,MilheimQuotation for installation of quick freezing cold storage, which has the & ldquo; Refrigeration & rdquo; Function, long-term cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage, medical cold storage, complete products, excellent quality and favorable price. There are also & ldquo; Air conditioning & rdquo; Function; However, the quick freezing storehouse is not a simple superposition of ordinary high temperature storehouse and air conditioning equipment. In order to adjust the gas composition in the storehouse quickly, it is necessary to ensure that the quick freezing storehouse has good air tightness. This has been confirmed by the theoretical research and a large number of practical experience of quick freezing warehouse.Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, 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 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, it needs to be checked in time.
There should be excellent drainage pipe standard around the warehouse, the soil temperature should be low, there should be interlayer under the cold storage, before the construction of the cold storage, the phase electricity of the relative volume shall be built according to the output power of the refrigeration unit. If the cold storage is water-cooled and radiating, the tap water pipeline shall be paved and the FRP cooling tower shall be built.supply,. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room, a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor, and relevant signs shall be set. If the mechanical panel is set in the main room, a button switch shall be added next to each refrigeration compressor.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.Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.Milheim,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, 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.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.Application of parallel compressor in cold storage: the requirement of refrigeration capacity is large, and to refrigeration compressors under Malige need to be used on weekdays; Long term operation, large load peak valley difference and significant departmental load; Frozen and refrigerated objects are novel foods that are easy to decay and degenerate, and have strict requirements for temperature and humidity.
