Preparation, 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.During the installation of polystyrene storehouse, the Perpendicularity Error of wall plate shall be corrected while the top storehouse plate is installed. The length of the top warehouse plate shall be mm shorter than the surface of the wall plate. After the installation of the top warehouse plate, the mm gap shall be marked with foaming material to ensure the sealing performance of the warehouse body.Zwitter steft,According to the technical requirements for the installation of cooling fan, when selecting the lifting point position, the position with good air circulation shall be considered first. Secondly, the direction of library structure is considered.First, use a hammer to pad the wood on the polyurethane warehouse board between the two warehouse boards, so as to make the boards closely close to each other. Two sets of connecting pieces shall be wedged between the wall panel and the wall panel, and the two sets of connecting pieces shall be fixed on the upper, outer and lower sides of the gap between the wall panel and the wall panel respectively. The lower connecting piece shall be as close as possible to the lower side, so that the post cast concrete can cover the connecting piece. After the gap between the plate and the plate ground is wedged with a connector, it shall be about mm wide. If it does not meet the requirements, remove the plate, trim the plate edge, pay attention to fix the two parts of the adapter on the edges of the convex and concave library plates respectively, the hammer shall be perpendicular to the wedge iron to prevent damaging the warehouse plate. The ground wedge iron at the upper and lower parts shall be wedged at the same time,Zwitter steftCold storage machine plate installation, and the wedge iron shall be fixed with rivets.La Laja,We should implement regular maintenance and daily maintenance, professional cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, large quantity, excellent quality and low price, fire resistance - Waterproof - high temperature resistance, strong and durable, safe and reliable, and maintain the operation rate of the compressor.There are many application scenarios of cold storage, which are different. For a long time, it provides various cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, on-site settlement, and has offices all over the country for long-term cooperation. Different purposes, functions and designs, so what needs to be understood in cold storage design?For the ground insulation of large cold storage, we can that the ground insulation of medium-sized cold storage is more complex than that of small cold storage, and the ground insulation operation of large cold storage with larger warehouse area will be more complex. The common operations are as follows: first lay the ventilation pipe to prevent the ground from freezing drum cracking, then lay the XPS extruded plate (staggered laying is required when laying the extruded plate), then lay the moisture-proof and vapor barrier on the upper and lower sides of the extruded plate, then pour the reinforced concrete (generally at least cm thick), and then make the emery floor or epoxy floor according to the requirements. Among them, the XPS extruded plate is also laid according to the warehouse temperature. For example, the XPS extruded plate with thickness of ~ mm needs to be laid in the general low-temperature cold storage, while the XPS extruded plate with thickness of ~ mm can be laid in the high-temperature cold storage.

The foundation of cold storage is affected by low temperature, and the water in the soil is easy to be frozen. Due to the volume of frozen soil, the ground will be broken and the whole building structure will be deformed. If the damage is serious, it may even make the cold storage unusable. Therefore, in addition to the thermal insulation layer,Zwitter steftInstallation of factory cold storage, the floor of low-temperature cold storage must be treated under the thermal insulation layer to prevent soil freezing. The bottom plate of the cold storage shall stack a large number of goods and pass through various loading, unloading and transportation machinery and equipment. Therefore the structure of the cold storage plate shall be firm and have large bearing capacity. In low temperature environment, especially in the process of periodic freezing and thawing cycle, the structure of each part of the cold storage and the building materials of the cold storage should have sufficient frost resistance.The function of refrigeration is & amp; amp; ldquo； Low temperature storage & amp; amp; rdquo； Introduction & amp; amp; ldquo； Loop type & amp; amp; ldquo； Cold chain logistics & amp; amp; rdquo；Whether there is dirt on the condenser and poor heat dissipation will lead to too high condensation pressure of the refrigerator. In order to protect the compressor, the machine stops running under the action of the pressure controller. When the heat dissipation is good, press the black reset button on the pressure controller, and the machine can automatically resume operation.Management DepartmentAll wiring shall be neat. All switches and keys shall be opened and closed sensitively, reliably and accurately. Special connectors shall be used for wiring, and power protection shall be provided for the box and each power branch.The products stored in the medical cold storage project must be managed by color code, so as to avoid the problem of purchase errors. In the process of handling, it is also necessary to strictly follow the instructions.If there is more air or refrigerant oil in the evaporator, the heat transfer effect will be reduced: once more refrigerant oil is attached to the inner surface of the evaporator heat transfer tube, the heat transfer coefficient will be reduced. Similarly, if there is more air in the heat transfer tube, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced,Zwitter steftConstruction organization design of cold storage installation, and the decline rate of warehouse temperature will be slowed down.

Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit, electric control system and other components of the cold storage. The connecting pipes shall be closely connected, and corresponding thermal insulation and protection measures shall be taken.packing,These are several very common cold storage materials. The use of these materials has greatly improved the thermal insulation and refrigeration performance of the cold storage, which makes people's retained items more convenient and reliable. With the continuous development of material technology, today's various cold storage materials emerge in endlessly, and the cold storage is different from each other. When purchasing, we should make reasonable comparison and select products suitable for our own use needs and economic conditions.The stacking and arrangement of cargo stacks in the controlled atmosphere warehouse have a great impact on the air circulation. A basic principle of air flow is to take the path with low resistance to obtain large air flow. If there is a dead corner caused by stacking obstruction and air circulation is difficult, the temperature will rise. For this reason, there shall be gaps between the cargo stacks and between the cargo stacks and the wall. The stacking arrangement of the cargo stacks shall be coordinated with the ventilation arrangement.Wall and floor fixtures shall start at corners. According to the plate layout drawing transport the two plates at the corner of the required device to the device location. According to the plate beam height and the model of the angle iron for fixing the mushroom head nylon bolt, drill a hole at the corresponding elevation in the middle of the plate width. When drilling, the electric drill should be perpendicular to the plate surface. Put the mushroom head nylon bolt in the hole, tighten the angle iron, and tighten it horizontally, so as to make the nylon bolt on the surface of the warehouse plate slightly concave. When setting up the wall panels foam data and other soft data should be laid on the floor slots along with the floor of the storehouse, the plane position of the wallboard and the verticality of the storehouse should be adjusted in time according to the location of the laying line so as to avoid damaging the storehouse. After the two corner panels are neutrally removed from the floor, and check whether the top elevation of the wallboard can be correct. After the position of the wallboard is correct, weld the angle iron on the plate beam and fix the inner and outer corners. When welding the angle iron parts, the angle iron parts of the warehouse plate shall be covered with a shield to avoid the high temperature of the welding ground baking the warehouse plate and welding slag on the warehouse plate during electric arc welding.Zwitter steft,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, 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.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.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.
