MedicinhartCold storage priceWhat are needed in quality inspection

For cold storage, it is very common in our production and life. Cold storage is very important for food freezing and preservation, but its energy consumption is very large in the use of cold storage. How can we solve this problem?

The foundation of cold storage is affected by low temperature, and the water in the soil is easy to be frozen. Due to the volume of frozen soil, the ground will be broken and the whole building structure will be deformed. If the damage is serious it may even make the cold storage unusable. Therefore, in addition to the thermal insulation layer, the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore, especially in the process of periodic freezing and thawing cycle,MedicinhartVegetable cold storage equipment installation, building structures are vulnerable to. Therefore, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.

Medicinhart.The water-cooled cold storage shall keep the cooling water tower clean and keep the air around the water tower circulating with low temperature,MedicinhartHow much does it cost to build a small fruit preservation cold storage, so as to avoid sundries from entering the cooling tower and reduce the heat dissipation efficiency.

Compression refrigerator is commonly used, which is mainly composed of compressor, condenser, 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.

When the liquid coolant passes through the evaporation pipe, it directly absorbs the heat in the warehouse and cools down.

Commissioning cold storage. After all parts of the cold storage are installed and connected, the cold storage can be started for cold storage commissioning. According to the needs of customers, adjust the value of the cold storage, the cold storage can reach the predetermined temperature, the cooling speed and the operation of the cold storage are normal, and the cold storage can be delivered for use. The cold storage installation unit shall also provide the cold storage user with training on cold storage use and management knowledge, as well as some after-sales training.

1 - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).

There are two reasons: the refrigerant charge is insufficient. At this time, just add enough refrigerant.

During the use of controlled atmosphere storage, it must be maintained on time and scientifically. No matter how good the equipment is, without scientific use and maintenance, its service life and effect will be discounted.

The construction of cold storage in site selection bears the circulation of low-temperature goods. Therefore, the transportation convenience of cold storage construction site should be given priority in site selection, such as proximity to roads, railways, etc. At the same time, the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.

Quality recommendation.During the cold storage commissioning, special personnel shall be assigned to ensure that the surface of the cold storage plate shall reflect evenly without condensation and cold running; Sealing conditions of joints and holes; Whether the warehouse door and delivery port are not tightly sealed, and timely deal with the problems of insulation and seal failure such as degumming and air leakage.

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,MedicinhartWhere is the installation of cold storage, 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.

The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.

There are two reasons: the refrigerant charge is insufficient. At this time, just add enough refrigerant.

OK or not?.A large number of personnel are not allowed to select goods in the warehouse. Close the warehouse door in time. When the warehouse door is opened, pay attention to whether the air curtain is opened or the door curtain is placed properly. Turn off the lights when leaving the warehouse.

The cold storage construction in the site selection undertakes the circulation of low-temperature goods. Therefore when selecting the site, such as close to roads and railways. At the same time priority should be given to the transportation convenience of the cold storage construction site, the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.

Moreover, the size changes often reflect bubble cracking or falling off, 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, 4110 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, achieve the effect of stable size, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.

There are many application scenarios of cold storage, which are different. For a long time, it provides various cold storage installation, cold storage installation cold storage construction, fruit preservation cold storage, medical cold storage, on-site settlement, honest operation, and has offices all over the country for long-term cooperation. Different purposes, functions and designs, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Fault phenomenon of cold storage: the dryer does not operate, the fuse is blown, the thermal relay acts, the high-voltage switch acts the compressor is locked, the line is falsely connected or loose. Fault phenomenon: it stops in a short time after the drying motor, and the environment
