Here we focus on polyurethane. Polyurethane is an ideal cold storage material in the cold storage project. Superior bonding properties make the foam and metal panels form a solid whole, so that no other adhesive materials are needed. When polyurethane is used as a cold storage project, rigid polyurethane foam is formed between the panels of the storehouse panel, and then solidified and pressed to form a multi shape storeboard, because the metal plate can roll out different waveforms, so that the overall rigidity is stronger and the bearing capacity is higher. Polyurethane filler board can meet the firmness and physical requirements of exterior wall and can be used in various cold storage projects. It is technically feasible and cost-effective. Yuanbao refrigeration believes that polyurethane is one of the new cold storage materials with great development prospects in the future. The thermal insulation materials of cold storage engineering should not only have good thermal insulation performance, but also be economical, applicable and environmental friendly. To ensure the smooth progress of our cold storage project we should not only inquire about the raw materials of the cold storage, but also the types of cold storage. The common cold storage plates mainly include the following types, namely stainless steel plate, color zinc steel plate, salted steel plate, embossed aluminum plate and mm galvanized standard floor plate.Cold storage is fireproof, flame retardant and high resistance. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, old brands, 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.Oaxaca,Material requisition for the installation requirements of the assembly fresh-keeping warehouse: according to the engineering design and construction material list, the materials shall be sent to the accessories warehouse, and the materials and accessories models shall be carefully checked.With the increasing use of cold storage, cold storage board, as an important structure of cold storage is also increasing. Because cold storage is different from other ordinary cold storage, it is important to the installation environment and temperature. Therefore,OaxacaHow to build fruit cold storage, some small problems may be ignored during installation. According to the following understanding.Nacala,Installation of box and operating device: the design of box shall be reasonable, and the appearance quality shall meet the requirements of beauty and practicality. All buttons, electrical switches, etc. shall be reliable, safe, long-term cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage, old brand, price advantage and quality guarantee! Easy to identify and operate. The indicator light shall be simple and clear. The device and each switch shall be installed on the upper side outside the warehouse door, which is easy to operate, read data and not easy to be damaged and shall be reliably fixed. The device box is installed on the door frame plate on the door opening side. The center line of the box overlaps the center line of the door frame plate. The bottom of the box is mm above the ground and is reliably fixed. The lighting lamp and door frame wire switch in the warehouse are installed directly below the device, and the height of the bottom edge of the switch box is about mm.Thermal insulation rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is ~ kg / m the thermal conductivity is only . ~ .w / (m.k), the cold storages using their white materials have significantly lower power consumption than those using other white materials.

Floor insulation of small cold storage the structure of small cold storage is usually called surface which is the lowest among all thermal insulation materials at present.These measures have achieved quite good results. Compared with several cold storages at a customer in Jining, that is, the top, wall and ground are made of color steel plate / stainless steel with appropriate thickness of polyurethane and other insulation materials, because the loading and unloading of small cold storage is often handled manually rather than forklift. Of course, if the height of the warehouse is high and the forklift is required for warehousing, the insulation board is not recommended for ground insulation, but the ground needs to be insulated separately like the ground insulation sample of medium-sized cold storage.Condensation pressure if the condenser has poor heat transfer, the condensation pressure will increase and the cooling power will decrease. For cooling, the heat transfer capacity will be insufficient, resulting in high condensation pressure.Connect the refrigeration system. Wires and copper pipes shall be used to connect the refrigeration unit,OaxacaCold storage maintenance and installation, 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.new product,Polyurethane refrigeration board uses light polyurethane as the internal material of refrigeration board. The advantage of polyurethane is very good heat insulation. The exterior of the cold storage is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is that it can prevent refrigeration, because the temperature difference inside and outside the board is large, and the temperature will disperse, which makes refrigeration more energy-saving and improves the working efficiency of refrigeration.The installation of top warehouse plate should be carried out alternately with the installation of wall plate, and the wall plate should leave a gap for withdrawing construction equipment; During the installation of the top warehouse plate, the end steel sheet at the overlap with the wall plate shall be disconnected for mm to prevent the cold bridge from running cold; Two layers of foaming materials shall be evenly and continuously punched on the joint surface between each top warehouse plate. Rivets shall be pulled and fixed at the internal and external lap joints of the steel plate, and the rivet spacing shall be mm; According to the design drawings, if there are supporting beams columns and supporting steel frames in the warehouse, the setting out and positioning shall be carried out and accurate and clear marks shall be made according to the requirements of the design drawings; Weld or install the support beam, column, support steel frame, and the welded junction shall be moisture-proof and treated according to the drawing requirements.The medical cold storage has been widely used in the industry. For the use of the medical cold storage project, the management personnel must be familiar with the operation steps of the medical cold storage project.

Immediate cooling is to install the condenser of the cold storage in the box or building of the cooling equipment, use the volatilization of the refrigerant to immediately cool the air in the air, and use the cold air to cool the objects that need to be cooled. This kind of refrigeration is characterized by faster cooling speed,OaxacaPrice of fresh-keeping cold storage, small heat conduction temperature difference and simple system software, so it is widely used.Honest management,The refrigeration of cold storage pays more and more attention to the needs of environmental protection and energy saving. Professional projects include: cold storage installation, installation of cold storage, cold storage construction, fruit fresh-keeping cold storage, medical cold storage and other related businesses. Merchants who hope to have this business please consider the wide scale of warehouse temperature control, the selection and placement of cooling equipment and the description of wind speed field, which are suitable for the cold storage needs of a variety of goods. Equipped with perfect storage temperature active detection, recording and active control equipment.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 two sets of connectors between the cold storage shall be wedged tightly, and the two sets of connectors shall be fixed at the upper, outer and lower sides of the cracks in the cold storage respectively. The lower connector shall be as close as possible, so as to facilitate the use of concrete to cover the connector in the future.Oaxaca,The combined cold storage door starts frequently or does not start for a long time, or does not stop for a long time, or stops before the storage temperature reaches.Application of parallel compressor in cold storage: the requirement of refrigeration capacity is large, and to refrigeration compressors under Malige need to be used on weekdays; Long term operation, large load peak valley difference and significant departmental load; Frozen and refrigerated objects are novel foods that are easy to decay and degenerate, and have strict requirements for temperature and humidity. - Installation of the vertical plate of the cold storage: select the angle first according to the site conditions and locate it (i.e. lock the vertical plate and the floor) to extend to both sides at this angle. Only lock the vertical plate and the vertical plate, and locate it when it meets the vertical angle. Put the beautiful plate in a conspicuous place. When installing it on the side of the evaporator, make the drainage pipe in advance, and make U-bend and silica gel outside the storage.
