Polyurethane foam: This is also a very common cold storage material. It has strong thermal insulation effect and strong mechanical strength. Now it is widely used and has a good application prospect.The temperature and humidity in the warehouse shall be kept uniform without movement; Try to finish the food in the warehouse at one time.Fort Wayne,If the warehouse is relatively small and you want to transform a miniature fruit fresh-keeping warehouse, you should ensure that the height in the warehouse is at least meters, because the top of the cold storage and the top of the warehouse should reserve a height of at least cm.The machine room of ammonia refrigeration system shall be equipped with exhaust assembly; The exhaust fan shall adopt anti motor. When the power supply is cut off due to unexpected refrigeration, it shall be able to ensure the reliable power supply of the exhaust fan. The overload protection of the exhaust fan should be applied to the signal alarm system without directly stopping the exhaust fan. The button box of the exhaust fan shall be concealed in the wall outside the ammonia compressor room.Girardot, compressor overload, low pressure too low, excessive air intake, compressor jamming.Polyurethane spraying is widely used in large and medium-sized refrigerators. Different well-known brands are produced at different prices, and the product quality is relatively large. However, it is not high-quality or good goods. This is the result of long-term cooperation.Feasibility of the design scheme: the design of the quick-frozen warehouse can not be taken for granted. Many restrictive factors should be considered. In practice, a reasonable design scheme should be given according to local conditions. For example the large-scale quick-frozen warehouse I built for my family should be refrigerated with ammonia in theory, because the refrigeration capacity of ammonia refrigeration is large, and I found that it is cheap to replicate cold through actual field investigation.

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.After years of service, the refrigeration oil inside the compressor should be replaced. The oil, copper, iron and impurities caused by wear are mixed in the refrigeration system, which thickens the refrigeration oil, deteriorates the fluidity and performance, reduces the effect, takes a long time,Fort WayneCold storage installation engineering manufacturer, increases the burden on the compressor, and the current will increase relatively compared with the new machine, which is a bad phenomenon.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) 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, 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.Welcome calls ,Drainage measures shall be provided for the villa room and overhead layer of the road surface of the cold storage engineering building.Polyurethane spraying is widely used in large and medium-sized refrigerators. Different well-known brands are produced at different prices, and the product quality is relatively large. However, it is not high-quality or good goods. This is the result of long-term cooperation.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.

The cooking materials and foods refrigerated in the quick-frozen warehouse contain a certain amount of fat, protein and starch. The existence of these nutrients will make molds and bacteria multiply and grow in large numbers. In order to do a good job in the hygienic management of cold areas and ensure the refrigeration quality of food and cooking raw materials it is necessary to carry out the hygienic disinfection of cold areas regularly.Convenient and efficient,Requirements for refrigeration equipment in quick freezing warehouse: the strict sealing of quick freezing warehouse is obviously different from that of ordinary quick freezing warehouse. Therefore, how to seal the refrigeration equipment is the key. First of all, all through wall pipelines must be equipped with sleeves, the frost flushing water return pipeline must be equipped with U-shaped bend water seal, and the main frost flushing and return pipeline outside the warehouse shall be equipped with air filling port to prevent the gas in the warehouse from being pumped out of the warehouse by negative pressure. In addition, the set fluctuation range of the warehouse temperature should not be too large to prevent excessive positive and negative pressure from damaging the warehouse body.Measure the power supply voltage according to the technical requirements for fluorine filling and commissioning of refrigeration system.Strong deformation resistance, not easy to crack, smooth, stable and safe. Polyurethane material has stable porosity structure and basically closed pore structure. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption performance. Under normal service and maintenance conditions, the life expectancy of rigid foam polyurethane insulation can reach more than years. During the structural life period, it can reach the unit price of dry, wet or electric corrosion under normal service conditions, while the unit price of insect, fungus or algae foam material is higher than other traditional insulation materials,Fort WayneFruit preservation cold storage installation company, but heating will increase the cost and the cooling cost will be greatly reduced.Fort Wayne,The refrigerant charge is insufficient. At this time, just add enough refrigerant.Features of quick freezing warehouse: the quick freezing technology is advanced, the frost free quick freezing method is adopted, the famous brand compressor and refrigeration accessories are configured,Fort WayneMeat cold storage installation company, and the automatic frost is adopted. The method can only be used by microcomputer. The refrigeration system adopts green refrigerant, which belongs to the international advanced refrigeration technology in the st century.Pay attention to the energy saving of the lighting system: the lighting of the cold storage should be considered comprehensively according to the area, height and warehouse temperature of the cold storage on the basis of safety, science and rationality, from the perspective of energy saving and environmental protection. The lighting in the cold storage is concentrated in the working area.
