Precautions for purchase and shipment when using the medical cold storage project, the speed must be strictly guaranteed during the purchase and shipment of products. If the temperature of the medical cold storage is about degrees, the opening time must be strictly within 25 minutes. If the temperature of the medical cold storage is left and right degrees, the opening time can not be too high, strictly within minutes.
Compression refrigerator is commonly used, which is mainly composed of compressor, throttle valve and evaporation pipe. According to the way of evaporation pipe device, it can be divided into direct cooling and indirect cooling. Direct cooling the evaporation pipe is installed in the refrigerated warehouse. When the liquid coolant passes through the evaporation pipe, it will directly absorb the heat in the warehouse and cool down.
Long-Beach.Reasonably design the division of fresh-keeping warehouse, such as cold storage room, freezer room, machine room, aisle, transportation platform, etc; The fresh-keeping storehouse shall be built indoors to avoid excessive temperature and poor refrigeration effect. If it is set outdoors, a sunshade shall be built; Wires shall not be outdoors,
When outdoor air enters the cold storage body, it will not only increase the cold consumption of the cold storage, but also bring water into the warehouse. The condensation of water will lead to the building structure, especially the heat insulation structure, being damaged by moisture and freezing. Therefore, the turbidity of cooling water shall be frequently, and whether the running, emitting, dripping, leakage and other conditions of the water supply system exist.
Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.
Fire retardant, flame retardant and high temperature resistant polyurethane is a kind of flame retardant self extinguishing material after adding flame retardant. Its softening point can reach more than 250 ℃, and it will decompose only at higher temperature. In addition, polyurethane forms carbon deposits on the surface of the foam, which helps to isolate the foam below. It can effectively prevent flame spread.
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 very important to select materials with good thermal insulation. Cold storage is a better material selection, and manufacturers need it in the production process of cold storage
Condensation pressure if the condenser has poor heat transfer, the heat transfer capacity will be insufficient power consumption increases. If the configuration of the cooling system is too small, resulting in high condensation pressure.
However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.
Development Curriculum.Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35 ~ 40kg / m3, the thermal conductivity is only 0.018 ~ 0.024w / (m.k), which is the lowest among all thermal insulation materials at present.
The closed cell structure and surface material of polyurethane rigid foam with good moisture-proof, waterproof and corrosion resistance make it have better air resistance and water vapor resistance, and it can be made into inlaid connection structure during forming, which is easy to assemble. It does not need additional insulating layer to prevent moisture and saves a lot of trouble in laying insulating layer.
We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, still has some use environment. In the market or marine transportation 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.
For the flushing (thawing) drainage pipe in the cold room with different temperature, an exhaust valve equipment shall be set before connecting the flushing (thawing) drainage pipe.
production.The refrigerator compressor unit generally adopts high-end units with guaranteed quality and strong operation stability. The evaporator adopts the imported joint venture refrigeration air-cooled evaporator which can effectively meet the refrigeration capacity of the refrigerator and ensure the refrigeration effect of the refrigerator. The refrigerator lamp adopts the special LED energy-saving lamp for the refrigerator, which has the advantages of low temperature resistance, low energy consumption and long service time, It can effectively save the operation cost of cold storage.
What are the common sense of protection and maintenance of fresh-keeping warehouse equipment? Nowadays, the application scope of fresh-keeping storehouse is more and more extensive. It is closely related to our daily life. In addition to food production factories, stores and restaurants have begun to build fresh-keeping storehouses. The main purpose of building a fresh-keeping warehouse is to ensure the freshness of food. There are many precautions in the process of fresh-keeping warehouse. After completion, there are also many protection and maintenance items. Regular maintenance and protection of fresh-keeping warehouse can increase its service life. Therefore, it is necessary for operators to understand some common knowledge about the protection and maintenance of fresh-keeping warehouse equipment. What are the common knowledge about the protection and maintenance of fresh-keeping warehouse equipment?
Whether the parameters of refrigeration equipment are consistent. When the cold storage leaves the factory, the temperature and temperature difference parameters of the cold storage shall be customized according to the user's requirements. After understanding the technical parameters of the cold storage, set the parameters on the refrigerator. During use, the air humidity is high and the defrosting interval is long. The common cold storage boards of cold storage include 100mm, 120mm, 150mm, 175mm and 200mm polyurethane thermal insulation boards, stainless steel plates, salt thick steel plates, embossed aluminum plates, polyurethane spraying, etc. on both sides or single and double sides, more general color steel tiles are produced and processed into hidden grooves, which have light weight, high compressive strength, good fire resistance, corrosion resistance and aging resistance, The cold storage board is simple and convenient to assemble, and is a wide range of raw materials selected for the heat insulation and heat preservation of the cold storage. The cost of stainless steel plate and salt plate increases and it is also easy to deform and damage the appearance.
Long-Beach.Frequently observe the operation state of the heart compressor of the cold storage equipment and its exhaust temperature. During the season change operation, pay special attention to the operation state of the system and adjust the liquid supply and condensation temperature of the system in time.
Cold storage construction: which one is suitable for you? Which one is suitable for you?
Disadvantages of single-layer cold storage: large; The surface area of the external enclosure structure of the cold storage is large, so the amount of thermal insulation materials is large, and the dry consumption of cold food is also large; For the low-temperature warehouse, the floor anti freezing treatment requires a large amount of work. When the cold storage is built at the water level it is impossible to deal with it, which is easy to cause horizontal freezing and swelling.
