1 - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, the drainage pipe shall be insulated).
The quick-frozen warehouse is easy to load and unload. All the plates and walls of the quick-frozen warehouse are produced by molds. You can choose tens of millions of products. Professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage and transaction safety are guaranteed. Through internal concave convex groove connection, loading, unloading and handling are convenient. The installation period is short. Small and medium-sized cold storage can be delivered in 2-5 days, The library body can be combined, separated or increased or decreased according to the needs of users.
Eil.Precautions for transforming the warehouse into a fruit preservation warehouse: determine the area and height of the cold storage according to the estimated number of fruits. In this way, after all, the warehouse is too large and the stored fruits are too few, resulting in a large waste of electric energy.
Moreover, polyurethane does not produce harmful gas at high temperature.
.The combined cold storage does not cool or the cooling effect is poor. Check whether the condenser of the refrigerator is dirty. Whether frost is too thick on the evaporator in the warehouse. Check whether the refrigerant is leaking (apply soapy water to the pipeline connection, and if bubbles are generated, it indicates that the refrigerant is leaking). And ask the combined cold storage engineering personnel to supplement the refrigerant and deal with the leakage. Check whether the sealing of the combined cold storage door is intact and eliminate it. Whether the refrigerator of the combined cold storage works. Whether the parameter setting of the computer controller of the cold storage is correct, and reassemble the cold storage door for installation. Check whether the cooler in the cold storage fails and replace it. Whether there is enough clearance for stacking articles in the warehouse and dredge them.
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.
Precautions for purchase and shipment when using the medical cold storage project, 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 common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.
As an important support for the development of cold chain performance, the standardized construction of cold storage refrigeration system is very important. It not only helps to rationalize the energy consumption of the cold storage system, but also has an important impact on improving the low-temperature preservation quality of commodities.
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.
Quality assurance.8. This shows the importance of regular oil discharge, descaling and air discharge in the refrigeration system of cold storage.
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.
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.
The foaming technology of polyurethane with strong stability 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, it can bear various internal and external combined loads such as wind force, self weight and normal collision and the insulation layer still does not separate and fall off from the carrier layer and remains stable in the state.
demand.During the use of the goods yard medical cold storage project, the stored goods must be in strict accordance with the relevant regulations. The goods should have a certain distance from the ground and wall of the cold storage. When stacking, the distance between the goods and the goods must be cm. At the same time, the distance between the goods and the cold fan should also be 100 cm. No goods can be stored within this range, This is also an important content in the use of medical cold storage engineering.
The refrigerator room with high-voltage cabinet and distribution cabinet shall be equipped with special tools and protection for high-voltage operation.
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, the drainage problem must be considered, and the following 8 points should be paid attention to during redesign and installation.
Eil.When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.
Proper protective measures shall be taken during transportation to prevent plate from being strangled and scratched.
The cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference, so as to make the cold storage more energy-saving and improve the working efficiency of cold storage.
