General quick-frozen warehouses are mostly cooled by refrigeration mechanisms,Lezhe Fruit and vegetable cold storage, and those with very low gasification temperature are used as coolant to evaporate under low pressure and mechanical conditions, so as to absorb the heat in the warehouse, so as to achieve the purpose of cooling and reduction.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.Lezhe ,If the refrigerator has been used for more than months or the high / low voltage switch often fails, or the refrigeration capacity is reduced, please arrange staff to clean the condenser. If the ultra-thin light box is repaired according to the above instructions for many times,Lezhe Which specialty of cold storage installation, and the refrigerator fault still sounds for a long time, please ask the maintenance personnel of the refrigerator to repair it.When the cold storage is used for the first time or shut down for a long time, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.ChegutuKg 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, polyethylene and polyphenylene grease. The density of thermal insulation material foamed by polyphenylene is thin, 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, but poor heat insulation. Therefore, the polyurethane sandwich board with very good performance belongs to the polyurethane sandwich board. Although it is slightly higher, the polyurethane board has very good thermal insulation performance and does not absorb moisture.We must often use insulation board in our life. It's just the structure of the refrigerator, but the refrigerator, as a in the home, still has some use environment. In the market or marine transportation, the environment of cold storage insulation board is not so optimistic. Professional cold storage installation, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage quality assurance. During the preferential activities, new and old customers are welcome to consult. The environmental differences inside and outside the cold storage insulation board are very large, so the temperature in the cold storage is strict. In such cases, the cold storage insulation board will have relevant problems, Let's understand that the water vapor pressure outside the plate warehouse of the lower cold storage is higher than that inside the warehouse, and the penetration of the envelope is carried out from outside to inside all year round. R gas in polyurethane is replaced by air and water vapor to damp polyurethane. Over time, moisture becomes more and more serious, and even water vapor condensation occurs, resulting in low thermal conductivity and reduced thermal resistance. In order to avoid and delay polyurethane moisture and prolong the service life of the insulation layer, it is effective to seal the hot side of the insulation layer, that is, to form a vapor barrier layer.A large number of personnel are not allowed to select goods in the warehouse. Close the warehouse door in time. When the warehouse door is opened, pay attention to whether the air curtain is opened or the door curtain is placed properly. Turn off the lights when leaving the warehouse.

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.After evacuation, then run the compressor and add gas from low pressure to sufficient volume.In order to ensure the safety of construction and cold storage operation, the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (mm thick) has a very large span of M,Lezhe Cold storage installation works, so as to cool the refrigerantSimple refrigeration is based on the volatilization of refrigerant in the condenser of the cold storage, and then input the refrigerant into the box or building of the refrigeration equipment to cool the air according to the heat exchanger. This kind of refrigeration has slow cooling speed, large total heat conduction temperature difference and complex system software, so it can only be used in less places, such as brine ice making and cold storage with constant temperature requirements.The assembled cold storage body often adopts double-sided color steel plate of polyurethane thermal insulation material, which has excellent thermal insulation performance, storage and circulation effect and reduces operation energy consumption. Of course, more important is the choice of refrigeration system. For example, at present, the refrigeration system of fluorine refrigerant is still the mainstream, but when selecting the type and power of cooling equipment, it is necessary to calculate the data for the installation of cold storage, and then make a high-quality choice.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, it is strictly prohibited to stack goods in the warehouse. The warehouse must be slowly reduced to the required temperature. For the low-temperature warehouse, it needs to be cooled in stages to avoid sudden changes in the temperature difference inside and outside the warehouse, resulting in the warehouse body.ranking,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.Pressure leak test: the system pressure leak test is the same as the blowdown work sample, which is required to be carried out by air compressor. - 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.Lezhe ,The installation of cold storage board is a link of the cold storage installation project. High price cold storage installation of various specifications, cold storage installation, cold storage construction, fruit preservation cold storage, medical cold storage. Waste merchants, industry, enterprises and power departments are welcome to visit and negotiate! The cold storage body and storage plate include: floor, vertical plate and ceiling plate. The installation of storage plates in different directions and precautions are as follows: enter the construction site, verify the construction situation according to the construction drawings, determine the equipment installation position, and the professional cold warehouse shall be installed. The cold warehouse shall be installed. The cold warehouse shall be constructed. The fruit fresh-keeping cold warehouse and medical cold warehouse shall have high pressure rating, good waterproof performance, fire and high temperature resistance strong overload capacity, corrosion resistance, evenly apply two layers of foaming material on the joint surface of male and female groove, and apply one layer of foaming material when installing polystyrene wall panel. The blanking shall be uniform and continuous; After the wallboard is installed in place pull rivets at the lap joint of the internal and external steel plates of the two wallboards for connection and fixation, and the rivet spacing in the warehouse should be mm; When connecting the library plate in the form of eccentric hook connection, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.Preparation, prepare the project planning of cold storage, and prepare the construction site and construction materials.
