The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.Cold storage, compressor overload, low pressure too low, excessive air intake, compressor jamming.Old city,The building structure of structural cold storage can be brick concrete structure or steel structure,Old cityDesign cold storage installation, which can be determined according to its own budget and actual needs. At present, most cold storages adopt single-layer steel structure and are equipped with combined thermal insulation warehouse body, unloading platform, refrigeration system, etc. according to the actual needs of cold storage circulation.During the use of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate, which will seriously reduce the local thermal insulation performance of the storage body.Wuxi,Disadvantages of multi-layer cold storage: the vertical transportation volume of the warehouse is large, the floor area ratio of each cold room is low; When the multi-storey cold storage is built on the foundation with poor ground resistance the foundation construction is complex. High cost; When prefabricated components are used, large construction equipment is required and the construction period is long.During the production of cold storage, the cold storage will produce fixed length, width and thickness according to the needs of various cold storage projects. Generally, cm thick cold storage plates are selected for high and medium temperature cold storage. The requirements for cold storage engineering plates of low-temperature storage and quick-frozen storage will be higher. Professional cold storage installation, installation construction, fruit fresh-keeping cold storage and medical cold storage ensure the quality, Guarantee service. Guarantee quality. Your satisfaction is our pursuit! Welcome to inquire. In this case, use cm or cm thick library board. When you budget the cold storage project, you can make a reservation according to the specific conditions of your cold storage temperature. If you don't make a reservation for the cold storage plate, you should pay attention to the density of the cold storage plate and the thickness of the steel plate when purchasing the cold storage plate. According to regulations, the foaming density of cold storage is per cubic meterPanel types of quick freezing warehouse: color plastic steel plate, salted steel plate, stainless steel plate, embossed aluminum, etc.
The lights in the warehouse are not on. Please check whether the switch fails and whether the bulb is damaged. Cut off the power supply when installing the lampshade, and pay attention to the waterproof of the lamp.Building plan and other relevant data of cold storage construction project. - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).Process inspection,Establish a perfect computer network, make the distribution of refrigeration supply chain scientific, and achieve the traceability of food safety. In the European Union, the United States and Japan,Old cityInstallation of large and small cold storage, all members of the food supply chain have the legal responsibility to implement traceability.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.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 ISO 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.
The use of large-scale cold storage is naturally very strict in installation and material selection. Therefore, in the face of the above possible situations, we can strictly screen the insulation board materials of cold storage, which can effectively alleviate or solve the above problems. However, at present, there are many fields using cold storage insulation board, so the details of the use environment should be considered for the wood making of many such products in the market.Good quality,Old cityCompanies that install large refrigerators,The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn, the long-term cold storage installation, installation, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.For the installation of power distribution system each contact shall be installed with wire number for maintenance.The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel, which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.Old city,Install the electric control system. The electric control system of the cold storage mainly includes electric controller, electric door, lighting and other electrical equipment in the cold storage. The power supply of the cold storage is required to be stable phase line, and the power supply or backup power supply can be used as required. The circuit shall have reasonable discharge and corresponding protective measures.The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.Cork board: cork board can be said to be a relatively primitive kind of cold storage. The thermal conductivity of cork board is relatively low, and it is easy to obtain, so it is not difficult to process, so it is generally used as the insulation board in some ordinary cold storage. If you want to pursue better thermal insulation performance, you have to look at the following materials.
