The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.
Grasp the key points. Now let's analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions, when the water vapor with high indoor temperature migrates outdoors, it is impossible to condense in the wall due to the obstruction of the cold storage.
JisrashShughur.The selection of wires shall have a safety factor, and the temperature of the wire surface shall not exceed 40 ℃ during unit operation or defrosting.
The wide, light and thin walls are made of rigid polyurethane foam at the same time as structural materials, making the whole structure have the advantages of light weight, large span and high load. The thinner polyurethane sandwich plate can meet the relevant provisions on building energy consumption limit, which allows the use of thinner plates during construction and saves building space.
.As a coolant, so as to achieve the purpose of cooling.
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.
The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.
With the development of the times, refrigeration devices are becoming more and more common. All aspects of life are inseparable from its use. Families will also be equipped with some simple refrigeration devices. For refrigeration devices such as cold storage, it is very important to select materials with good thermal insulation. Cold storage is a better material selection, and manufacturers need it in the production process of cold storage
The volume of cold storage the size of cold storage shall be calculated according to the volume occupied by the stacking of goods stored in the cold storage, plus the corridor from row to row the indoor space between the stack and the wall, and the gap between the ceiling and the packaging room. After determining the volume, the length width ratio of the cold storage shall be determined. When designing the cold storage, such as working intermediate, packaging and combing room, special tool warehouse and loading and unloading platform, so as to ensure the quality of the cold storage.
Panel types of quick freezing warehouse: color plastic steel plate salted steel plate, embossed aluminum, etc.
Service first.Grasp the key points. Now let's analyze the production and use requirements of the cold storage. There is no condensation in the cold storage. Condensation in the cold storage or in the insulation layer is harmful. During the drying process of the new wall or under winter conditions when the water vapor with high indoor temperature migrates outdoors, it is impossible to condense in the wall due to the obstruction of the cold storage.
Initial operation unit of cold storage equipment: regularly observe the oil level and oil return of the compressor and the cleanliness of the oil. If the oil is dirty or the oil level drops, it shall be solved in time to avoid adverse effects.
It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is 15-20 degrees. If our humidifier is connected with the warehouse, there is no temperature compensation, even if
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 300 boxes to 400 boxes, which increases the space a lot.
Credit guarantee.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, 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.
The controlled atmosphere warehouse is mainly used for the storage and processing of fruits. It can keep the low temperature of fruits in the cold warehouse and make the storage time longer. The walls of the cold warehouse are equipped with heat insulation panels, and the bottom is equipped with quick boards to prevent moisture and heat from the outside, Today, we'll take you to know some precautions about how to store fruits in the cold storage: disinfection treatment before fruits are put into the fruit preservation cold storage: the cold storage should be disinfected before fruits are put into the fruit preservation cold storage. Sulfur is used for disinfection. Generally, kg of sulfur can be used for disinfection of 100 cubic meters, and then use sawdust to ignite and close the doors and windows. Don't open the doors and windows within two days. The storage volume of fruits should not be too large every time. It's good if the daily purchase volume is about 10%.
Able to withstand the harsh local climate and its changes. Neither high temperature nor severe cold climate will cause irreversible damage or deformation to the external insulation system. The drastic change of the surface temperature of the external wall, such as the sudden shower after a long time of exposure, or shading during exposure, will not cause damage to the surface of the cold storage.
JisrashShughur.Polyurethane spraying is widely used in large and medium-sized refrigerators. Different well-known brands are produced at different prices, and the product quality is relatively large. However, it is not high-quality or good goods. This is the result of long-term cooperation.
During operation, the water temperature will still drop, and the humidification amount will be reduced by 70% at 5 ℃.
The efficiency of the compressor is low, and the refrigerating capacity can not meet the load requirements of the warehouse: due to the long-term operation of the compressor, the cylinder sleeve, ring and other parts are seriously worn the long-term cold storage installation, installation, construction, fruit preservation, medical cold storage and other brand products, the designated products are complete, the quality is guaranteed, and the sealing performance will be reduced accordingly with the increase of the matching clearance, The gas transmission coefficient of the compressor will also be reduced, and the refrigeration capacity will be reduced. When the refrigerating capacity is less than the heat load of the warehouse, the temperature of the warehouse will drop slowly.
