Points of multi-storey cold storage: small, 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,lemurCold storage installation manufacturer, etc.Whether there is dirt on the condenser and poor heat dissipation will lead to too high condensation pressure of the refrigerator. In order to protect the compressor, the machine stops running under the action of the pressure controller. When the heat dissipation is good, press the black reset button on the pressure controller, and the machine can automatically resume operation.lemur,The air conditioning warehouse is equipped with standby power supply. After eliminating the line and load problems it is the maintenance of external irresistible power lines. If the refrigerated goods in the air conditioning warehouse are expensive or vulnerable to temperature changes, it can be considered to equip the air conditioning warehouse with standby power supply to ensure the operation of refrigeration equipment in the cold storage in a short time after power failure. Large air conditioning warehouses can be considered to be equipped with generator sets, Automatically switch the generator set for power generation after power failure for use. For example, dual mains power can be used.What should be considered in building a cold storage? In these aspects, 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?Klaeng,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.The ultrasonic town is a patented technology with a shaped energy cover, which increases the effective humidification amount by -% per hour. What are the reasonable aspects of the design of the quick freezing warehouse?The three-dimensional automatic cold storage adopts a computer, which can complete the loading, unloading and stacking in the storage, the control of storage temperature and the operation of refrigeration equipment.

Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), the size changes often reflect bubble cracking or falling off,lemurHow much is the installation of cold storage per square meter, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.Check whether the compressor phase current is stable.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.Safety and health,Artificial refrigeration keeps the room at a constant temperature. The walls, floors and flat roofs of large cold storages are laid with thermal insulation materials with a certain thickness to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, which can be determined according to their own budget and actual needs. At present, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body, unloading platform, refrigeration system, system, pipeline system, etc. according to the actual needs of cold storage circulation.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.

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, the management personnel must be familiar with the operation steps of the medical cold storage project.Safety and health,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.Establish a perfect computer network to realize the scientization of refrigeration supply chain distribution and traceability. In the European Union, the United States and Japan, all members of the food supply chain have the legal responsibility to implement traceability.The cold storage shall be regularly overhauled and maintained so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.lemur,The equipment configuration is reasonable and the service life of the quick freezing warehouse is long. The reasonable equipment configuration of the quick freezing warehouse can greatly prolong the service time of the quick freezing warehouse. Some compressors are easy to be damaged when they work at full load for a long time, just like the shift at work, so that the compressor can work and rest in turn.Fault phenomenon: fan motor overload,lemurInstallation of small cold storage, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Cold storage fault phenomenon: dryer does not operate, compressor line is disconnected fuse is blown, thermal relay acts, compressor is locked, line is falsely connected or loose fault phenomenon: it stops in a short time after drying, ambient temperature is too high, condenser is blockedThe refrigerant charge is insufficient. At this time, just add enough refrigerant.
