Suggestions on the quantity of polyurethane cold storage insulation materials: cold storage investment is a long-term and profitable investment. A high quantity of hair can certainly reduce the initial investment, but it is necessary to grasp a certain limit and comprehensively consider the long-term energy consumption and initial investment, because the insulation effect of polyurethane cold storage insulation materials has a parabolic linear correlation with its bulk weight; A large number of studies have shown that the foam bulk density has better thermal insulation performance at ~ kg / cubic meter. Therefore, it is usually recommended that the number of thermostat refrigeratory outlets should be ~ square / ton. - floor installation of cold storage: first level the floor, then install the floor, select a beautiful floor and put it in a conspicuous place, and do a good job in the floor and evaporator drainage system.Arezzo,The cooler on the refrigeration unit is very easy to be dirty, so it should be cleaned on time according to the specific situation. To maintain stable heat conduction and practical effect. Good heat removal and cooling. There is no need to accumulate dirt around the refrigeration unit.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,ArezzoInstallation price of fresh-keeping cold storage, 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,ArezzoQuick freezing and cold storage installation works, but the cost is low.Chashniki,However, long-term continuous operation will inevitably lead to equipment aging, so reasonable maintenance is particularly important.Kg to kg / m, and the steel plate thickness generally needs to be more than . mm to meet the standard. On the market, the main raw materials of special cold storage board for cold storage project are polyphenylene, and the thermal insulation coefficient is not very high; After a certain ratio of polyethylene, it can foam cold storage insulation materials with appropriate density and good thermal insulation effect, and has high load-bearing capacity; Polyphenylene resin has strong water absorption,ArezzoInstallation of factory cold storage, but poor heat insulation. Therefore, the polyurethane board has very good thermal insulation performance and does not absorb moisture.The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed, the butt joint shall be filled with foaming material, and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.

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, science and environmental protection. When designing and installing the cold storage, the drainage problem must be considered, and the following points should be paid attention to during redesign and installation.The equipment is built according to the application requirements of low-temperature power distribution. This is reflected in the following six points: low temperature hall, closed platform, electric refrigeration door, anti-collision flexible seal, platform height adjustment equipment (lifting channel) completed & amp; amp; ldquo； Door to door & amp; amp; rdquo； Type loading and unloading operation has become the symbol of modern cold storage.Generally speaking, the construction of cold storage is to ensure the quality of buildings with its strict heat insulation sealing, firmness and frost resistance.agent,The cold storage belongs to a kind of refrigeration equipment. Compared with the refrigerator, its refrigeration area is large, but they have the same refrigeration principle. So how to maintain the cold storage every day. Today I'll introduce how to do a good job in the daily management and maintenance after the installation of the cold storage.The service life of the cold storage depends on the quality of the refrigeration equipment, but it also has a great relationship with the proper daily management and maintenance after the installation of the cold storage. Many times, people often ignore the latter point. In daily life, as long as we maintain and maintain the cold storage regularly, we can greatly improve the service life of the cold storage and reduce the cost.In order to maintain a constant low temperature in the cold storage, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color. Therefore, cold storage building is different from general industrial and civil buildings, prepare the project planning of cold storage, and prepare the construction site and construction materials. All kinds of materials for cold storage construction are customized according to the needs of customers. Sort out the construction site that meets the requirements, transport all installation materials to the construction site, check the material quality and model, and start the installation of cold storage after confirmation.Quality inspection report,The cold storage shall be regularly overhauled and maintained, so as to reduce the failure rate of the refrigeration unit and achieve good refrigeration effect.The air washing and ventilation of the cold storage is in the long-term sealed LIUCai storage, and the carbon oxide is released due to the respiration of vegetables. If the accumulation is too high, it will have an adverse effect on the storage of vegetables. Therefore, ventilation device or air washing device is designed in the general warehouse.The closed cell structure and surface material of polyurethane rigid foam with good moisture-proof, waterproof and corrosion resistance make it have better air resistance and water vapor resistance and it can be made into inlaid connection structure during forming, which is easy to assemble. It does not need additional insulating layer to prevent moisture and saves a lot of trouble in laying insulating layer.Arezzo,It is strictly prohibited to place articles with pollution and peculiar smell around the cold storage. The surrounding environment of the cold storage must be cleaned and disinfected regularly every day, and the door of the cold storage must be locked.During installation the plates shall be handled with care. Rough operation is strictly prohibited. Burrs shall be removed at the cutting opening to prevent scratching the plate surface and workers.The factors affecting the installation cost of cold storage are as follows: cold storage construction: the site selection shall comply with laws and regulations and meet the relevant requirements for food hygiene and. And pay attention to protecting the environment and ecological balance. In addition, it shall be conducive to production
