Curva How much is the cold storage installed per square meterIndustry Research Report

the production shall be carried out in strict accordance with the operation rules specified in ISO quality operation

Technical assurance measures for the installation of cold storage: during production in the production workshop, self inspection and inspection application shall be carried out to ensure that the factory pass rate is, and unqualified products are not allowed to leave the factory.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.Curva ,Electrothermal defrosting: the electrothermal element defrosts the controlled atmosphere reservoir. The management system of controlled atmosphere storage is simple, easy to operate, easy to realize automation, but it consumes more power.All 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.Heidelberg ,The common phenomenon of quick freezing storehouse is that the temperature of quick freezing storehouse can't drop down or drops slowly. Now, a simple analysis is made on the reasons for the slow drop of temperature: the cold capacity loss of quick freezing storehouse is large due to poor thermal insulation or sealing performance; the poor thermal insulation performance is due to insufficient thickness of thermal insulation layer of pipeline and warehouse thermal insulation wall, resulting in poor thermal insulation and thermal insulation effect, It is mainly caused by improper selection of insulation layer thickness in design or poor quality of insulation materials in construction.The door of the combined cold storage is not tightly closed. Please adjust the distance between the hinge on the door and the door lock and the storage body.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.

Reasonable space: the power consumption of the cold storage is calculated according to the cold consumption of the cold storage, which usually includes two parts: the cold consumption during cargo cooling and refrigeration; It is the cooling consumption of the refrigeration room itself and operation management.Protective fence shall be set around the door of the controlled atmosphere storage with eye-catching signs.Regular oil discharge, descaling and air discharge: when there is a .mm thick oil film in the evaporator coil, in order to maintain the set temperature requirements, the evaporation temperature will decrease by ℃ and the power consumption will increase by more than ; When the scale on the water pipe wall in the condenser reaches mm the condensation temperature will rise by ℃ compared with the original temperature, the power consumption will increase by about . It can be seen that it is coldassets,The overall construction achievements of the cold storage project have been put into use, and the service life can reach years.The cold storage board uses light polyurethane as the inner material of the cold storage board. The advantage of polyurethane is that the thermal insulation performance is very good. The exterior of polyurethane cold storage board is composed of SII, PVC color steel plate and stainless steel plate. The advantage of this is to prevent the temperature transmission of cold storage board due to large internal and external temperature difference, and corresponding protection measures shall be taken for the installed equipment.

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, its installation quality will directly affect the temperature of cold storage. As an important structure used in the cold storageDuring the installation of cold storage board in cold storage, the cold storage board should pay attention to the details of its installation, find out the problems that are easy to be ignored, and avoid the wrong installation, which will affect the use of the cold storage or the whole installation process,Curva Design and construction of cold storage, so as to waste resources and increase the cost.Actual factors affecting the increase of exhaust temperature of fresh-keeping warehouse: low intermediate cooling efficiency, or too much scale in the intercooler of fresh-keeping warehouse affects heat exchange, the suction temperature of the later stage must be high, the butt joint shall be filled with foaming material, and the mm wide color steel plate shall be sealed at the butt joint with pull riveting.Curva ,The construction of cold storage in site selection bears the circulation of low-temperature goods. Therefore, the transportation convenience of cold storage construction site should be given priority in site selection, such as proximity to roads,Curva How much is the cold storage, railways, etc. At the same time, the location of the cold storage should avoid large pollution sources and direct sunlight, and the construction of the cold storage should have good drainage and ventilation conditions.Polyurethane foam foam dimensional stability: cold storage polyurethane foam in severe temperature changes or at a relatively low temperature will appear dimensional changes (as contraction), the size changes often reflect bubble cracking or falling off, and these will inevitably affect the normal use of cold storage. In addition to regular simulation of performance testing,Curva Price of small installed cold storage, more emphasis is placed on the selection of high quality materials: special energy polyether compound use, so that the foam body mesh structure, greatly improving the foam low temperature resistance. At present, polyether commonly used in spraying materials contains a large number of functional components, and a large number of linear structures formed after reaction are difficult to be stable at low temperature; The use of the energy crosslinking agent also greatly improved the dimensional stability of the foam. The selected polyether adopts catalysis in the production stage, and the reaction is complete, so that the polyether maintains a high reaction rate (that is, it can react completely with black material); Some manufacturers in order to achieve foam appearance does not produce deformation phenomenon and add a hole component to foam material, reduce the bubble closed hole rate, achieve the effect of stable size, but it has sacrificed the thermal insulation performance of polyurethane cold storage insulation material foam.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.
