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.
The selection of cold storage is very important for cold storage, because cold storage is different from ordinary cold storage. The temperature in cold storage is usually low, and the air temperature, humidity and environmental requirements are relatively high. When selecting cold storage, attention must be paid to the selection of cold storage with better temperature. If the selection of cold storage is not good, the temperature in the cold storage is difficult to, which is easy to cause the deterioration of products in the cold storage, or the refrigeration compressor in the cold storage often works, wasting more resources and increasing the cost.
Antigua-and-Barbuda.After years of service, the refrigeration oil inside the compressor should be replaced. The oil, copper, iron and impurities caused by wear are mixed in the refrigeration system, which thickens the refrigeration oil, deteriorates the fluidity and performance, reduces the effect takes a long time, increases the burden on the compressor, and the current will increase relatively compared with the new machine, only with sufficient cold storage installation skills can we ensure that the cold storage is more energy-saving and power-saving after installation, and is not prone to failure, convenient use and management and long service life.
Floor insulation of small cold storage the structure of small cold storage is usually called surface, that is, 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.
Another reason is that there are many refrigerants in the system. In this case, find the leakage point first, focus on the connection of each pipeline and valve, repair the found part, and then fill in sufficient refrigerant.
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.
Before the installation of the controlled atmosphere warehouse we should also know how long the time demand for freezing goods is. After the installation of the controlled atmosphere warehouse, it can be divided into fresh-keeping warehouse, cold storage, frozen storage and quick-frozen storage. The first thing for the fresh-keeping warehouse is to store regular items, the first thing for the cold storage is to store items below zero, and the first thing for the frozen storage is items around zero, The freezing time code takes 24 hours. If it is put into the quick freezing warehouse, it only takes 2 to 10 hours to reach the phenomenon of quick freezing. In the process of depositing goods, if the temperature is too low, it will affect the normal temperature of the deposited goods. The high price cold warehouses of various specifications are installed, installed constructed, fruit fresh-keeping cold warehouses, and medical cold warehouses are supplied in time, High cost performance, has become the preferred brand for many wire products, welcome to buy! It will also affect the shelf life.
Requirements for the cold storage time of the device: the cold storage of the refrigeration system using ammonia as refrigerant shall be supported in the place with low population density around.
quality.1 - precautions for floor installation of cold storage: the floor shall be installed flat, the uneven part shall be leveled with materials, and the locking hook between the plates shall be locked to ensure that the warehouse surface is flat without hollow feeling. (note that if this drainage system is installed outdoors in the north, the drainage pipe shall be insulated).
The polyurethane insulation board shall be connected by plug-in notch connection, because it has higher strength when connecting in this way.
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, 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, 4110 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, the span between the top storage plate supports (lifting points) shall comply with the following provisions: the polystyrene top storage plate (100mm thick) has a very large span of 3M, and the polyurethane top storage plate (100mm thick) has a span of 5m.
query.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.
Nowadays the application of fresh-keeping storehouse is more and more extensive. It is closely related to our daily life. Fresh-keeping storehouse is mainly to ensure the freshness of food.
The butt joint between the top warehouse plate and the end of the top warehouse plate shall be treated to prevent air leakage and cold running. After all the top warehouse plates are installed, the butt joint shall be filled with foaming material, and the 80mm wide color steel plate shall be sealed at the butt joint with pull riveting.
Antigua-and-Barbuda.Emergency measures during the use of the medical cold storage project, it may also encounter power failure or power failure. In fact, most medical cold storage projects will be equipped with emergency equipment, so that the medical cold storage project can achieve the effect of normal power supply. Once the automatic temperature or humidity monitoring system is abnormal, the cold storage door should be closed in time, So as not to expose more air conditioners, resulting in corresponding problems in the quality of stored products. The medical cold storage project also has a self rescue system in time. If the temperature of the cold storage exceeds the limit, the system cooling system will also be turned on. When the temperature returns to normal, it will be automatically turned off.
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, medical cold storage and transaction safety are guaranteed. Through internal concave convex groove connection, loading, separated or increased or decreased according to the needs of users.
Goods in and out frequently, throughput
