USAInstallation and design of cold storageWhat are the selection criteria

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; amp; gt; 100 mm; The electrical box can be fixed on the building wall or on the angle steel frame.

Cork board: cork board can be said to be a relatively primitive kind of cold storage. The thermal conductivity of cork board is relatively low, and it is easy to obtain, so it is not difficult to process, so it is generally used as the insulation board in some ordinary cold storage. If you want to pursue better thermal insulation performance, you have to look at the following materials.

USA.For the installation of refrigeration unit, oil separator shall be installed for semi sealed or fully sealed compressor, and an appropriate amount of oil shall be added in the oil. When the evaporation temperature is lower than - 15 ℃, gas-liquid separator and an appropriate amount of refrigeration oil shall be added.

Energy saving and power saving: the design cost of quick freezing warehouse mentioned above is very low but it has a great impact on the cost of quick freezing warehouse and later use cost. The electricity bill is often an important expenditure item in the later stage. The design scheme of the show can greatly reduce the power consumption of the quick freezing warehouse. The selection of the back sunny side of the quick freezing warehouse, the tightness of the quick freezing warehouse door, and the temperature difference between the adjacent cold storage rooms should not be too large are all issues that we need to consider. There are also some tips, such as the use of air curtain machine on the quick freezing warehouse door. We remind users to use parallel units in quick freezing warehouse as far as possible and start them reasonably.

.The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following 6 points: a low-temperature hall, a closed platform, and a platform height conditioning equipment (lifting channel) are built to complete & ldquo; Door to door & rdquo; Type loading and unloading operation has become a symbol of modern cold storage.

Because polyurethane sheet has excellent thermal insulation performance an anti-collision flexible seal, it can reduce the thickness of building envelope and increase indoor use area under the same thermal insulation requirements.

Floor insulation of small cold storage the structure of small cold storage is usually called surface, 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, loading and unloading, 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.

The new cold storage material is made of rigid polyurethane or polystyrene foam insulation sandwich panel, which is made by high pressure foaming process and can be made into various lengths and specifications to meet the different requirements of the users.

Frequently check and determine whether the working voltage of switching power supply meets the regulations, and the working voltage shall be 220V & plusmn; 10％. When the wholesale of fresh-keeping warehouse equipment is not needed for a long time, the main switching power supply of the freezing warehouse shall be disconnected, and it shall be ensured that the fresh-keeping warehouse equipment will not return to moisture and will not be polluted by other chemical substances such as ash.

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.

Information recommendation.There are two kinds of refrigeration in the cold storage group: immediate refrigeration and simple refrigeration.

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.

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.

In order to maintain a constant low temperature in the cold storage,USAFreezer manufacturer, attention should be paid to the installation of cold storage panels in Guizhou: the floor, wall and flat roof of the cold storage are laid with a certain thickness of thermal insulation materials to reduce the incoming heat from the outside. In order to reduce the absorption of solar radiation, the surface of the external wall of the cold storage is painted white or light color. Therefore, cold storage building is different from general industrial and civil buildings, and has its unique structure. Cold storage buildings should prevent the entry of air and the diffusion of water vapor.

Welcome calls .Reasonably adjust the cold storage evaporator and defrost in time: Generally speaking, every 1 ℃ increase in the evaporation temperature of the cold storage can save energy by 2 ~ 5. Therefore, on the premise of meeting the refrigeration process of the product, the liquid supply can be adjusted to increase the evaporation temperature as much as possible.

Scrubbers are often used in controlled atmosphere warehouses. The scrubber is more complex and requires spraying device, so it is less used. The type of air washing device to be used depends on the equipment and environmental conditions. In winter, the outside temperature is low, so ventilation is appropriate, while the controlled atmosphere storage and are different.

Technical assurance measures for the installation of cold storage: during production in the production workshop, the production shall be carried out in strict accordance with the operation rules specified in ISO9002 quality operation, 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.

USA.The quick-frozen warehouse is easy to load and unload. All the plates and walls of the quick-frozen warehouse are produced by molds. You can choose tens of millions of products. Professional cold storage installation, installation of cold storage, cold storage construction, fruit preservation cold storage, medical cold storage and transaction safety are guaranteed. Through internal concave convex groove connection,USAFruit preservation cold storage money, loading, unloading and handling are convenient. The installation period is short. Small and medium-sized cold storage can be delivered in 2-5 days, The library body can be combined, separated or increased or decreased according to the needs of users.

Features of quick freezing warehouse: the quick freezing technology is advanced,USAInstallation of industrial cold storage, the frost free quick freezing method is adopted the famous brand compressor and refrigeration accessories are configured, and the automatic frost is adopted. The method can only be used by microcomputer. The refrigeration system adopts green refrigerant, which belongs to the international advanced refrigeration technology in the 21st century.

Fault phenomenon: fan motor overload, fan deformation; Fan motor fault; Fan motor thermal relay fault (aging); Loose wiring; Cooler blocked; Large exhaust resistance. Fault phenomenon of cold storage: the dryer does not operate, the compressor line is disconnected, the fuse is blown, the thermal relay acts, the high-voltage switch acts the compressor is locked, and the environment
