During the use of cold storage, attention shall be paid to the collision and scratch of the storage body to avoid the depression and corrosion of the storage plate, which will seriously reduce the local thermal insulation performance of the storage body.The quick freezing storehouse of vegetables and fruits is not suitable to use exhaust cooling, but use fan to supply air for refrigeration, because the gas in the quick freezing storehouse needs to be circulated and dispersed regularly to avoid carbon oxide poisoning caused by high concentration of carbon oxide in local areas. Therefore, in the quick freezing warehouse, the refrigeration equipment needs to be used together with the air conditioning equipment. The selection of refrigeration equipment is different from that of low-temperature freezer and ordinary quick freezing warehouse.Zaragoza square,During the welding of refrigeration pipeline, a blowdown outlet shall be reserved to blow the sewage from high and low pressure with nitrogen in sections. After the sectional blowing is completed, the whole system shall be blown until no dirt is found. The blowdown pressure is .MPa. - precautions for vertical plate of cold storage: vertical plate displayDiyarb Najm,The selection of equipment for the construction of equipment cold storage is closely related to the size, type and budget of the cold storage.The equipment is built according to the application requirements of low-temperature distribution. It is reflected in the following points: a low-temperature hall, a closed platform, an electric sliding refrigerated door, an anti-collision flexible seal, 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.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,Zaragoza squareCold storage installation manufacturer,Zaragoza squarePharmaceutical warehouse management system, 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.

It is equipped with temperature compensation to automatically adjust the water temperature. The water temperature of ultrasonic atomization is - degrees. If our humidifier is connected with the warehouse there is no temperature compensation, even in the work, the water temperature is lowBecause our large-scale fresh-keeping warehouse is generally composed of many thermal insulation boards, and the gap between each board is the place that needs maintenance. During construction, these gaps will generally be sealed with sealant, but if it is found that there are seal failure departments in the fresh-keeping warehouse during use, it is necessary to lay some foam on the floor of the cold storage tank.Where is it,More and more people begin to build cold storage, and most people choose to use cold storage for cold storage construction. Why? Why do people choose cold storage for construction? What are the advantages of cold storage? The following is a detailed introduction.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.There are many kinds of cold storage. According to the material, it can be divided into color steel plate, stainless steel plate and salted steel. Among them, color steel plate has strong anti rust ability, but stainless steel plate has strong anti rust ability, while salted steel has both beautiful appearance and anti rust ability. According to the layout, it is divided into flat plate and wave plate. The former is flat after the surface material is formed, the thickness of stainless steel is .mm and mm, without color requirements; The thickness of salted steel plate is .mm, without color requirements; The thickness of PE paint baking board is .mm, .mm ivory white, titanium white and white gray. The most important thing for the cold storage is the applicable temperature of the cold storage. It is divided according to the insulation thickness of the storage plate. The thickness of the sky floor of the mm storage plate is mm,Zaragoza squareInstallation price of large cold storage, and the thickness of the vertical plate is mm and mm which is suitable for the insulation conditions of - ℃ ~ - ℃; mm storage plate: the thickness of the ceiling plate is mm and the thickness of the vertical plate is mm, which is suitable for the thermal insulation conditions of ℃ ~ - ℃. The thickness of the ceiling plate and the vertical plate of mm storage plate is mm, which is suitable for the thermal insulation conditions above ℃. In fact, there are many other classification methods of cold storage. Determined by the current processing technology, it can be divided into standard plate and non-standard plate according to the width and size range of warehouse plate, including standard plate vertical plate width wa = mm, heaven and earth plate width WB = mm, vertical angle plate W = mm, W = mm, compressor overload WB and W.

Cold storage, lack of refrigerant, low pressure too low, excessive air intake, compressor jamming.technological innovation,What should be considered in building a cold storage? In these aspects, food cold storage is a systematic project of artificial refrigeration to ensure food quality and reduce food decay in a low-temperature environment. Refrigeration technology affects the design of food cold storage, meets the needs of refrigeration technology, convenient production, energy saving and cost reduction. What problems should be considered in the construction of food cold storage?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, and the exhaust temperature will also increase.The structure of contemporary cold storage is in the development trend of prefabricated building cold storage. It is made into prefabricated components of cold storage including steam barrier and heat insulation plate to ensure on-site assembly. Its advantage is that the project construction is convenient, rapid and movable,Fault phenomenon: high current or tripping during unit startup, and problems of user air switch; Input voltage is too low; The star angle conversion interval is too short (it should be ~ seconds); Hydraulic cylinder failure (no reset); Intake valve failure (too large opening or stuck); Loose wiring; Host failure; Main motor fault; TR time relay is broken (relay unit).During the cold storage commissioning, special personnel shall be assigned to ensure that the surface of the cold storage plate shall reflect evenly without condensation and cold running; Sealing conditions of joints and holes; Whether the warehouse door and delivery port are not tightly sealed and timely deal with the problems of insulation and seal failure such as degumming and air leakage.Floor insulation of medium-sized cold storage the structure of medium-sized cold storage is what we often call the surface, that is, while the ground needs to be insulated separately. At present, the common operations in the market are: laying the ground with XPS extruded board, laying moisture-proof and steam isolating SPS materials above and below the extruded board respectively, and then pouring concrete or reinforced concrete.
