Cold storage plate features: good thermal insulation performance, light weight, high strength, anti-aging, beautiful appearance.Cold storage has good water tightness. Polyurethane rigid foam has low water absorption, good permeability to water vapor, foam holes, disconnected and closed porosity of more than %. It is a dense microporous foam material, and is not easy to permeate. It belongs to hydrophobic materials.Badwaslau,Pressure leak test: the system pressure leak test is the same as the blowdown work sample, which is required to be carried out by air compressor.Step of cold storage design: selection and laying of cold storage thermal insulation materials. The use of cold storage thermal insulation materials must be adjusted to the time, which not only has excellent fire resistance, but also has high cost performance. There are several types of cold storage insulation materials. One is the plate produced and processed into a fixed shape and specification with fixed length, total width and thickness. The cold storage plate with relative specification and model can be selected according to the installation of the warehouse body. The high and medium temperature cold storage generally adopts cm thick cold storage plate, cm or cm thick cold storage board is generally used for ultra-low temperature cold storage and freeze-cleaning cold storage; Another kind of cold storage can be sprayed with polyurethane spray paint and polyurethane foam, and the raw materials can be sprayed into the brick or concrete warehouse of the cold storage to be built immediately. After shaping, it is both waterproof and thermal insulation. Thermal insulation materials include polyurethane, polystyrene grease, etc. Polyurethane is non hygroscopic and has good fire resistance, but the cost is high; Polystyrene resin has strong water absorption capacity and weak fire resistance, but the cost is low.Talsi,We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home, 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,BadwaslauMedicine cold storage, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, so the temperature in the cold storage is strict. In such cases because a large number of items need to be insulated, 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. R 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.Install the temporary lighting facilities in the warehouse, install and arrange the construction electrical equipment, and do a good job in rain proof, moisture-proof, anti-collision, anti binding and other safety protection.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.
Compression refrigerator is commonly used. It is mainly composed of compressor, throttle valve and evaporation pipe. The evaporation pipe is installed in the refrigeration warehouse. When the liquid coolant passes through the evaporation pipe, it directly absorbs the heat in the warehouse and cools down.However, not all controlled atmosphere reservoirs can choose to adjust with a large depth, which still needs to be determined according to the actual needs of fans and places. We can adjust the energy-saving effect of the control fan from the production design link, coupled with the user's energy-saving effect of the hot air fan, so that the energy-saving effect of the hot air fan will be significantly improved.When installing polyurethane insulation board, ensure that its surface is smooth and flat without scratch and warpage.Production departmentAble to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall, such as the sudden shower after a long time of exposure, or shading during exposure, will not cause damage to the surface of the cold storage.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, a moisture-proof and heat insulation layer should be set to keep the cold storage board building moisture-proof and air-proof performance and good sealing.Cold storage design segmentation: several different partitions shall be reasonably planned and divided according to purpose and temperature. For example: processing room, sorting room, quick freezing room, refrigeration room, channel, unloading platform, etc.
Generally speaking, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation, sealing firmness and frost resistance.Good quality,The product shade warehouse is a warehouse location below ℃ and the sun cannot be straight. The humidity is % ~ % relative humidity, and there are corresponding strict requirements for the wall,BadwaslauCold storage installation equipment, ceiling, ventilation, disinfection and epidemic prevention of the warehouse. The refrigeration system adopts full-automatic microcomputer electrical technology and does not need to be on duty. It mainly stores western and Chinese grass materials and instruments, according to the temperature of the environment a few minutes faster and an hour slower. Of course, the amount of inventory and the temperature in winter and summer, refrigeration is also divided into air cooling, water cooling, direct cooling and simple cooling. Different refrigeration is fast and slow, but most small refrigerators are air-cooled, The market share is about %.The spacing of pull rivets at inner and outer corners is mm and mm respectively; After the polystyrene library is installed, the wall panel joints shall be evenly sealed and decorated with silicone sealant.Badwaslau,After the cold storage at the corner is installed, the next cold storage can be installed along the direction of the corner. Adopt the similar installation of Zhang cold storage to install the thermal insulation board of the storage. Professional cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, advanced technology, strict testing, more affordable price and more preferential. Welcome to consult. Pay attention to its compactness and continuous uniformity.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 (mm thick) has a very large span of M, and the polyurethane top storage plate (mm thick) has a span of m.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?
