These are several very common cold storage materials. The use of these materials has greatly improved the thermal insulation and refrigeration performance of the cold storage, which makes people's retained items more convenient and reliable. With the continuous development of material technology, today's various cold storage materials emerge in endlessly, and the cold storage is different from each other. When purchasing, we should make reasonable comparison and select products suitable for our own use needs and economic conditions.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,ChichigarpaInstallation and construction of cold storage, 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.Chichigarpa,This high-quality CA library not only wants to bring a certain effect in use, but also wants the hot air fan to reduce energy consumption in use. Every customer wants to achieve a better return with less investment. Therefore, today, I will introduce how the CA library can achieve energy-saving effect.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,Quick freezing storehouse is widely used. There are many kinds of temperature in quick freezing storehouse will not cause damage to the surface of the cold storage.Baracaldo, and multi temperature or double temperature can be realized to meet the needs of different customers. Fault phenomena: unit current is large and voltage is too low; Loose wiring; The unit pressure exceeds the rated pressure; The oil separation core is blocked; Device failure; Host failure; Main motor fault; Fault phenomenon: the unit cannot be started and the fuse is broken; The temperature switch is broken; Loose wiring; Thermal relay of main motor acts; The thermal relay of cold storage fan motor acts; The transformer is broken; No power input (unit); Failure not eliminated (unit); The actuator is faulty.With the increasing use of cold storage, cold storage board, as an important structure of cold storage, is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore, some small problems may be ignored during installation. According to the following understanding.The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve ring and other parts are seriously worn, the long-term cold storage installation, installation,ChichigarpaFruit and vegetable cold storage, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.

Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, because the insulation effect of polyurethane cold storage insulation materials has a parabolic linear correlation with its bulk weight; A large number of studies have shown that the foam bulk density has better thermal insulation performance at ~ kg / cubic meter. Therefore, it is usually recommended that the number of thermostat refrigeratory outlets should be ~ square / ton.The selection of wires shall have a safety factor, and the temperature of the wire surface shall not exceed ℃ during unit operation or defrosting.Other aspects: in the design process of food cold storage, it is also necessary to consider the cooperation between the cold storage and on-site fire fighting, ventilation, water and electricity systems. It should meet the requirements of safety, science and environmental protection. When designing and installing the cold storage, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.Standard requirements,If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.The construction structure of structural cold storage can be brick concrete structure or steel structure, which can be determined according to their own budget and actual needs. At present, unloading platform and are equipped with combined thermal insulation storage body, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.Points of multi-storey cold storage: small, which can save land; When the storage capacity is the same, the surface area of the outer enclosure structure is smaller than that of the single-layer cold storage, so that the cold consumption can be reduced, the dry consumption of food can be reduced, and the machinery and equipment cost and operation and management cost can be reduced accordingly. At the same time, due to the saving of thermal insulation materials, the civil construction cost per unit area is low and the investment cost is small; The multi-storey location can be reasonable, such as the cooling room can be used as the cold storage room, the attic on the top floor can be built into the ice making room, etc.

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, which has the & ldquo; Refrigeration & rdquo; Function, long-term cold storage installation, cold storage installation, cold storage construction, fruit fresh-keeping cold storage,ChichigarpaFresh and cold storage installation company, 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.Potential development,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.Vibration shall be prevented during the whole operation of the refrigeration unit. In addition to the abrasion of the lifting mechanical equipment, vibration will continue to cause loosening or cracking of the upper connecting pipe of the generator unit. If abnormal noise is found during the whole operation of the equipment, it shall be shut down for inspection before operation. The maintenance functions of the refrigeration unit have been set and do not need to be adjusted.For water-cooled units, the turbidity of cooling water shall be frequently the cooling water shall be replaced frequently, and whether the running, emitting, dripping, leakage and other conditions of the water supply system exist.Chichigarpa,After being stored in the medical cold storage project, ventilating medical products may also emit some odors. Once these odors are stored in a certain quantity, they will also have a certain impact on other products. Therefore, we must carry out regular ventilation in the process of daily use so as to effectively reduce the storage time of products. If the medical cold storage project uses row tube refrigeration, the image of frosting may appear after use for a period of time. If we do not defrost in time, it will also affect the effect of. Therefore, so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day, and the door of the cold storage must be locked.
