Through internal concave convex groove connection, loading, unloading and handling are convenient. The installation period is short. Small and medium-sized cold storage can be delivered in - days,HogerFactory installed cold storage, The library body can be combined, separated or increased or decreased according to the needs of users.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.Hoger,Building plan and other relevant data of cold storage construction project.Core tip: in the cold storage project, only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation, and is not prone to failure,The construction structure of structural cold storage can be brick concrete structure or steel structure, which can be determined according to their own budget and actual needs. At present, most cold storages are constructed with single-layer steel structure, and are equipped with combined thermal insulation storage body, unloading platform, refrigeration system, system, pipeline system etc. according to the actual needs of cold storage circulation.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, 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, due to the good sealing of the quick freezing warehouse, 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. - 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.
Watertight polyurethane rigid foam has low water absorption, good permeability to water vapor, and state of foam pores. It is not connected with each other, and the obturator rate is more than %. It is a dense microporous foam material, which is more dense than the surface of the air, and is not easy to permeate. It is an hydrophobic material.The exhaust pipe and return pipe shall have a constant slope. When the condenser is higher than the compressor, the exhaust pipe shall slope towards the condenser and a liquid ring shall be installed at the exhaust port of the compressor. Prevent the gas from cooling and liquefying back to the high-pressure exhaust port after shutdown, and cause liquid compression during restart.The combined cold storage door starts frequently or does not start for a long time,HogerFast cold storage, or does not stop for a long time, or stops before the storage temperature reaches.Quality inspection report,As a coolant, make it evaporate under low pressure and mechanical conditions to absorb the heat in the storage, so as to achieve the purpose of cooling.In the cold storage project, we should first realize the temperature requirements of cold storage and the importance of cold storage to cold storage. Because the cold storage project has high environmental requirements such as temperature,HogerGeneral cold storage installation, attention should be paid to the performance and material of the cold storage board when selecting the cold storage board.. Maintenance of food cold storage. In a position convenient for operation outside the door of the refrigerator room a main switch for cutting off the power supply of the refrigeration compressor shall be set. This switch shall be able to stop the operation of the refrigeration compressor, and relevant signs shall be set. If the mechanical panel is set in the main room, a button switch shall be added next to each refrigeration compressor.
Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and in the production process of cold storage, there will be no condensation in the cold storage of the plant. Condensation inside the cold storage or inside the insulation layer is harmful. Irreversible damage or deformation occurs in the new external insulation, and the external surface temperature of the external wall changes sharply. For example, which can be used in many industries. As we all know, the cold storage has great requirements for the thermal insulation effect of building materials. If the thermal insulation effect of building materials is not good, the cold storage will consume more energy during operation, and can not guarantee a good refrigeration effect. The performance of polyurethane insulation board meets the construction requirements of cold storage, so a large number of polyurethane insulation boards need to be used in the construction of general cold storage. Next, let's understand the physical properties of polyurethane insulation board.Superior quality,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.The selection of thermal insulation material is important to the quality of controlled atmosphere storage; The selection of thermal insulation materials for the controlled atmosphere storage must be adjusted to local conditions, which should not only have good thermal insulation performance, but also be economical and practical. The thermal insulation materials are divided into several types. One is the plate processed into fixed shape and specification, with fixed length, width and thickness. The plate of corresponding specification can be selected according to the installation needs of the controlled atmosphere storage. The cm thick plate is generally selected for the medium temperature controlled atmosphere storage, cm or cm thick plates are generally selected for low-temperature controlled atmosphere storage and frozen controlled atmosphere storage. The other can be sprayed with polyurethane for foaming, and the materials can be directly sprayed into the built brick or concrete warehouse. After setting, it is moisture-proof and heat-insulating. The heat-insulating material plates include polyurethane, polyphenylene grease, etc. Polyurethane does not absorb water and has good heat insulation. It is a long-term cold storage installation, installation, construction, fruit preservation and medical cold storage. Welcome to consult. But the cost is low; Polyphenylene resin has strong water absorption and poor thermal insulation, but the cost is low. The structure of modern controlled atmosphere storage is developing towards assembly and the storage components including moisture-proof layer and thermal insulation layer are made to achieve on-site assembly. The point is that the construction is convenient, fast and movable but the cost is relatively high.Initial stage of cold storage equipmentHoger,The wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials, making the whole structure have the advantages of light weight, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.Anti odor floor drain shall be set on the pavement of refrigeration room and refrigeration unit room, and the height width ratio of floor drain water seal shall not be less than mm. The elevator shaft, electronic pit and other places convenient for drainage shall be provided with drainage and equipment to avoid backflow of water.Cold storage is fireproof, flame retardant and high resistance. Professional cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage and other special products, old brands, price advantages and guaranteed quality. Polyurethane is a flame retardant self extinguishing material after adding flame retardant. Its softening point can be above degrees Celsius and will only be decomposed at higher temperatures. In addition, the ash formed on the surface of polyurethane will be in its foam, and this ash will help isolate the foam below. It can effectively prevent the spread of fire. Moreover, polyurethane will not produce harmful gas at high temperature.
