When installing the polyurethane insulation board, the adhesion between the panel of the polyurethane insulation board and the thermal insulation material is short and often high.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, because a large number of items need to be insulated, 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.Famagusta,Whether the warehouse can drill through the wall. The construction and installation of cold storage shall be like the installation of air conditioner, and the external unit shall be connected with the unit in the cold storage.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.Shedertzee,Installation of unit electrical box: the unit electrical box shall be installed near the unit; Vertical installation. If the unit is installed on the top of the warehouse, the distance between the box bottom and the top of the warehouse must be & amp; gt; mm; The electrical box can be fixed on the building wall or on the angle steel frame.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, small heat conduction temperature difference and simple system software, so it is widely used.The equipment that needs to be installed in the warehouse and put into the warehouse shall be installed in place or placed in an appropriate position in the warehouse; The wall warehouse board shall be installed from the corner of the warehouse body, 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, the eccentric hook shall be loosened once before installation to ensure reliable locking during installation.

In the low temperature environment, especially in the periodic freezing and thawing cycle, the building structure is also vulnerable to. Therefore,FamagustaFresh storage cold storage, the building materials of the cold storage and the structure of each part of the cold storage should have sufficient frost resistance.The location of fresh-keeping warehouse installation shall be in a stable and convenient place; (if it is a local fruit farmer, it should be installed near the fruit source)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, the heat exchange area of the evaporator will be reduced, the heat transfer efficiency will be significantly reduced, and the decline rate of warehouse temperature will be slowed down.Project scope,During the installation of long-span top warehouse plate, if the supporting steel beam has been installed in the warehouse, the top warehouse plate and the supporting steel beam shall be fixed with pull rivets during the installation of each warehouse plate, so as to ensure that each lifting point can be installed at the same time during the installation of the top silo plate; The lifting point shall ensure that there are at least two points along the width direction of each warehouse plate.Step of cold storage design: define the volume of the cold storage warehouse. The size of the cold storage should be based on the design of a large number of agricultural products to be stored for a long time. This volume is calculated based on the essential volume of stored goods accumulated in the cold storage the installation and construction of the lifting layout shall be realized before the installation and construction of the top silo plate, plus the row to row corridors, the indoor space between the pile and the wall, the ceiling and the gap of the packaging house. After the volume of the cold storage is determined, the length and height width ratio of the cold storage shall be determined. Necessary auxiliary engineering buildings and equipment shall also be considered in the design of cold storage, such as working intermediate, packaging and combing room, special tool warehouse, loading and unloading platform, etc.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.

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,FamagustaInstallation of cold storage and quick freezing storage, 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.Quality recommendation,Large space rate of quick-frozen warehouse: for quick-frozen warehouses of the same size, reasonable design schemes store more goods than unreasonable ones. For the fixed size quick freezing warehouse, how to design it to maximize its space rate is often an important problem considered by our designers. In the design scheme of Lukang medical quick-frozen warehouse, we reasonably designed to expand the original storage capacity of boxes to boxes, which increases the space a lot.Heat pump, hot water, refrigeration and other fields. Supporting downstream products include: household air conditioner, multi on-line modular machine, small water ground source heat pump, etc. At present a single scroll refrigeration unit can achieve ~ HP.Moreover, polyurethane does not produce harmful gas at high temperature.Famagusta,When opening and drilling is required for the top warehouse plate or wall plate, the internal and external setting out and positioning shall be carried out according to the drawing design requirements, return hole liquid inlet hole, water supply hole and drainage hole shall be opened with a hole opener. Construction treatment shall be carried out in time after opening and drilling, and the orifice shall be closed with foaming material or sealant to prevent air leakage and cold running; The door, vent and delivery port shall be decorated with wrapped edges and fixed with pull rivets,FamagustaCold storage of professional installation company, with a spacing of mm and mm outside.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, and the decline rate of warehouse temperature will be slowed down.Vent valve or water seal well shall be set at the outlet of flushing (thawing) drainage pipeline. Cold proof measures shall be taken for exhaust valves and water sealed wells in severe cold areas.
