San-AntonioTheit can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.
There are two reasons: the refrigerant charge is insufficient. At this time
Because polyurethane sheet has excellent thermal insulation performance, just add enough refrigerant.
Kampung Pasir Gudang Village.System blowdown: the standby air compressor is used. When the air compressor cannot be solved, the ammonia compressor can be used instead.
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, uniform temperature in the warehouse, and can bring harmful gases such as carbon oxide out of the warehouse during storage.
.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?
The quantity is large, and a special tally room (area) is set according to the needs of production and operation. The temperature of the tally area is usually controlled at 0 ~ + 7 ℃.
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.
The physical properties of polyurethane insulation board are relatively good which can meet different needs. The polyurethane insulation board is also strict in the selection of materials. It is a special product manufacturing enterprise integrating R & D, and service. It has long been specialized in cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage and medical cold storage. It improves the overall performance of the polyurethane insulation board and enables the polyurethane insulation board to work for a long time, Polyurethane insulation board has also become one of the main exterior wall materials.
The startup of the air-cooled refrigerator unit shall depend on whether the rotation direction of the fan is correct. If the forward rotation can be started for operation, the reverse rotation indicates that the power wiring is reversed,Kampung Pasir Gudang VillageHow much does it cost to install the cold storage, and the phase sequence must be replaced before startup.
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), 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.
Online consultation.The products stored in the medical cold storage project must be managed by color code, so as to avoid the problem of purchase errors. In the process of handling, it is also necessary to strictly follow the instructions.
In order to ensure the safety of construction and cold storage operation, the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (100mm thick) has a very large span of 3M, and the polyurethane top storage plate (100mm thick) has a span of 5m.
It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is 15-20 degrees. If our humidifier is connected with the warehouse, there is no temperature compensation, even if
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.
Highly recommended.Technical assurance measures for the installation of cold storage: during production in the production workshop, the production shall be carried out in strict accordance with the operation rules specified in ISO9002 quality operation, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and unqualified products are not allowed to leave the factory.
Refrigerated vehicle planning Kende refrigeration reminds enterprises with the construction needs of logistics refrigerated warehouse project to conduct in-depth communication with the project and refrigerated vehicle planning on warehouse location and actual use needs when determining the final installation construction mode, so as to ensure the smooth circulation of goods in logistics refrigerated warehouse.
The two sets of connectors between the cold storage shall be wedged tightly, and the two sets of connectors shall be fixed at the upper, so as to facilitate the use of concrete to cover the connector in the future.
Kampung Pasir Gudang Village.During operation, the water temperature will still drop, and the humidification amount will be reduced by 70% at 5 ℃.
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.
For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least 15cm thick), the XPS extruded plate is also laid according to the warehouse temperature. For example,Kampung Pasir Gudang VillageConstruction and installation price of cold storage, the XPS extruded plate with thickness of 150 ~ 200mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of 100 ~ 150mm can be laid in the high-temperature cold storage.
